Is it possible to install a saw blade on a grinder. Wood disc for a grinder: choosing the right tool Disc for an angle grinder for wood

When working with wooden surfaces, the question arises whether the disc is suitable for angle grinders when working with wood. Today, the grinder is used when performing various operations, because it was made universal tool.

With the help of such a device you can grind, polish, cut, saw and perform many other functions. She copes well with such material as wood, but before work you need to study some recommendations.

In this article we will talk about the disks for angle grinders, their types and attachments used when working with wood. There are many of these accessories for angle grinders and they all differ in purpose and characteristics.

Initially, you need to decide on the tool with which you plan to cut wood. It is known that discs are produced for standard sizes of angle grinders. The smallest diameter is 115 mm, but such a tool is used in extreme cases.

The main advantage of such a grinder is its compactness, but it is extremely inconvenient to work with such a tool for a long time. The best option for woodworking is a grinder with a 125 mm disc. It is this size of the circle for wood that is the safest, and therefore it has become widespread.

To work with angle grinders on wood, a special disk is required. It is strictly contraindicated to cut wood with abrasive or diamond wheels. This will not help to cope with the task, but rather lead to the destruction or overheating of the tool.

It is forbidden to work as an angle grinder with installed disks that are intended for circulars. Because it poses a threat to human health and life.

When choosing a circle for a wood grinder, it is important to pay attention to the inner diameter of the shaft, which, according to the standard, is 22.2 mm.

Older models of angle grinders may have a different shaft diameter, so this point is important to consider when buying the appropriate circle.

The optimal circle for woodworking has following parameters: 125x22.5 mm. Bulgarians for discs from 150 mm and above are not recommended for wood, as the risk of serious injury increases. It is better to use tools for cutting or grinding wood under 125 or 115 circle diameters.

Not only power tools, but also hand tools are a serious danger if safety rules are not followed. The nozzle on the grinder for cutting wood in this case is no exception.

Choose the right circle for the tool: according to the diameter of the outer and landing, and also depending on the type of wood.
Select the appropriate operating mode for the tool.
Do not use wheels that show obvious signs of damage.
Resort to application individual means protection.

It is not necessary to carry out work without the use of a protective cover, with the exception of carrying out manipulations for peeling, grinding and polishing wooden surfaces. It is especially dangerous to work with saw wheels. It is strictly forbidden to resort to installation on angle grinder discs from a circular or other instruments.

For angle grinders, you can only use consumables that are directly intended for it. In conclusion, it should be summed up and noted that grinder wheels for woodworking are no less popular than abrasive wheels. After all, the use of such consumables greatly facilitates the work of a person, and also saves time.

saw on wood for a grinder;
cutting discs;
planes;
grinding.

Each of these parts must be used for its intended purpose.

A saw blade for wood for a grinder consists of a metal circle with a chain attached to the edge. The design of special sawing tools is similar to those used for chainsaws. But are made saw blades from tungsten carbide.

When a disk for a grinder on a tree hits a solid obstacle in the wood - knots, resin, metal, its base rotates without breaking the chain. With chain nozzles, it is quite easy to clean the logs from knots and bark, to give them the necessary initial shape.

The thickness of the circle should be within 2 mm.
The depth of the cuts made can be within 20 mm.
Cutouts can be empty or filled with copper.

With the help of a saw blade for wood for an angle grinder, you can solve a fairly large number various tasks associated with construction, repair work, furniture production and landscaping of the backyard territory.

Saw blades for wood for grinders, visually practically do not differ from circles for circular saw. But they are made of a completely different metal. Until recently, these products were rare, now there are quite a lot of high-quality tungsten carbide wood wheels on the market.

Important: in no case, do not even try to set the circle from the circular to the grinder. Theoretically, this can be done through an adapter, but circular discs are designed for low speeds and in the grinder, in the vast majority of cases, they warp or simply scatter.

saw blades trademark Rapide are made from high quality tool steel and are highly wear resistant. The carbide teeth of this blade are equipped with tungsten carbide tips and are precision ground.

Rapide 180mm saw blades for wood have 36 or 60 alternately set teeth, which, after long-term use of the blade, can be sharpened using special equipment.

This design allows you to successfully cut chipboard, MDF, laminated panels, hard and soft woods, getting a very clean and even cut. The Rapide 180mm saw blade has special temperature slots that serve to cool the blade and prevent it from overheating.

The inner diameter of such a circle - the seat - is 22.2 mm, which corresponds to seat angle grinder (grinder). Outside diameter circle - 180mm and the use of a circle of this size is provided for angular grinder exclusively corresponding diameter - 180mm.

The use of this disc on any other power tools not specified by the manufacturer, or on angle grinders of a different diameter, is extremely dangerous and may result in serious injury.

One of the important advantages of Rapide saw blades is their ability to be used for various types of cuts - both for transverse and longitudinal. The manufacturer recommends a permissible number of revolutions up to 80 meters per second.

The 180mm wood cutting disc for a grinder is quite popular among professional craftsmen for various carpentry work, sawing branches, logs and cutting firewood. This circle is often used in the manufacture of furniture, the manufacture of any structures or buildings from wooden beam.

Characteristics of the saw blade for wood 180 mm:

Producing country	Germany

Material handling	MDF, Wood, Hardwood, Softwood, Chipboard
outer diameter	180.0 (mm)
Inner diameter	22.23 (mm)
Number of teeth	60 / 36
Amount in a package	1 PC.)

Chain saw blades for wood: application advantages

AT this case the saw circle is performed using a chain from a chainsaw. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency.

A chain drive on a tree for a grinder is also considered the safest. Using this attachment greatly reduces the chance of injury if the tool jams.

If the disk hits a solid element of the tree (for example, a knot) during operation, then the chain is not destroyed. This is done by turning the base. Such nozzles are very popular when it is necessary to clean the trunk of a tree from bark and knots.

Wood saw blades for angle grinders with a chain are used for various kinds of work. With their help, you can remove tree branches, as well as cut boards of small thickness. Functionality chain products allow you to use them as peeling tools. They do an excellent job of removing the bark.

With the help of a saw blade, you can make an even cut parquet board, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material to be processed with such a nozzle should be no more than 4 cm. Otherwise, the device is likely to overheat.

Various manufacturers produce and cutting wheels on wood specifically for angle grinders, for example, a Bosch cutting wheel. Their design is significantly different from the design of discs for circular saws.

cutting tools

bevelled;
straight;
in the form of a trapezoid.

The first version of the shape of the teeth is considered universal. It is suitable for all types of wood with small amounts of work. When sawing wood from soft varieties, it is quite possible to use discs for a grinder on wood with a straight tooth. Trapezoidal teeth are capable of processing quite solid products from wood: chipboard, fiberboard, OSB boards.

In addition, cut-off wheels vary in diameter. The minimum size is 115x22 mm. The most commonly used circles with a diameter of 125 mm, they are universal and suitable for a wide range of jobs.

Maximum possible size- 230 mm. But the latter option is undesirable to use when working with wood, as the likelihood of injury increases. Depending on the size chosen, the depth of cut in the wood will also be different.

Universal or beveled wood saw blades for grinders are best used if it is planned to carry out work rarely in extreme cases, and any type of wood can be used as processed materials.
Wood discs with straight teeth are recommended if the technological process involves working with coniferous and softwoods.
The trapezoidal shape of the tooth is suitable for cutting medium-density chipboard. Most often, such a tooth is universal and suitable for sawing hardwoods.

A cutting disc for wood for an angle grinder 125 mm is classified not only by diameter and, accordingly, the depth of cut, but also by shape, frequency and number of teeth.

If you plan to use a wood saw blade for a 125 mm grinder from time to time, and you don’t know what kind of wood, you will need to cut it. That the best option there will be a circle with variable beveled teeth.

For cutting conifers, as well as for any other soft wood, products with straight teeth can be used.

A wider range of uses for a trapezoidal tooth. A wood saw blade for a grinder 125x22.2 mm with trapezoidal teeth, capable of cutting a medium-density chipboard. It also handles bilaminated particle boards, USB boards and medium density fibreboards with ease.

different kinds

cord brushes;
end circles;
petal nozzles;
emery circles;
cutting nozzles.

Rough processing of wood is carried out with the help of special cord brushes. End discs are designed to level the edges of parts, which is often required when miter sawing workpieces. They make a great file replacement. The widest range sanding attachments- at the petal circles.

Depending on the size of the abrasive grain, the wood surface can be cleaned with varying degrees grinding. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved.

The system of trapezoidal petals, which are stacked with a three-quarter overlap on each other, wears rather slowly. If the embossed surface wooden product complex, then used petal discs with a radial arrangement of abrasive strips.

Using sandpaper or sandpaper special nozzle allows you to grind quite large areas wooden surfaces. The ability to quickly change the sanding cover makes these tips versatile. When deleting old coatings often use peeling nozzles.

Typically, this is a wire brush attached to metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for fixing the bristles on the perimeter of the disc.

When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, they must be cleaned to healthy wood.

Grinding disk for wood for a grinder: characteristics

With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out peeling work of varying degrees of complexity. The modern market offers a wide range of such nozzles. They are classified according to several indicators: form, design and purpose.

Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove the excess part of the tree from the end surface of the board. They may have special spikes or crumbs.

Roughing discs on wood for grinders are also used to level the surface of the boards. Such circles are equipped with special spikes, which are placed on a flat plane. This feature is very useful, as it allows you to polish the boards from which the flooring is constructed.

On sale you can find peeling products consisting of twisted wire. They are usually called korshchekami. Such attachments for a grinder for woodworking are of two types, depending on the features of their structure. The first option provides for the presence of a base in the form of a glass to which the wire is attached. The second type is a disk with a wire fixed along the edge.

Brushes are used to eliminate paintwork materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.

Note! For wooden parts it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types wood.

Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give wood unusual view, artificially age it.

However, with the help of a grinder with a peeling wire nozzle, only small volumes of wood can be processed. Thus, for brushing in industrial scale this item is not recommended.

Grinding is one of the most popular processes for which angle grinders are used. With the help of such a tool and a set of nozzles, it is possible to carry out rough and gentle processing of metal, stone and wooden surfaces.

As a rule, grinding precedes polishing of workpieces. The nozzles that are used in this case may consist of sandpaper or felt material.

The petal disk for the grinder was widely used. This tool consists of a circle (base), along the edges of which sandpaper petals are fixed. They may have different grain sizes. This indicator is selected depending on the nature of the work.

The use of a petal wheel allows for roughing workpieces from different materials. It can also be used for fine sanding. For finishing, fine-grained petals are used.

Today you can find another variety grinding discs to Bulgarian. Some abrasive products are fixed to the base with a special Velcro. To use such a circle, it is necessary to screw it onto the tool spindle.

Polishing is the softest wood treatment. For polishing work, which relate to the finishing stage of turning a particular material, special felt discs are used.

And also in the tool market you can find circles, the working part of which consists of thick fabric. Nozzles for polishing grinders are very popular when working with wood, as their use allows you to bring the surface of the material to the smoothest possible state.

If you decipher the abbreviation angle grinder, then it is clear that it is the finishing that is the main purpose of the grinder.

cord brushes

They are mainly used for primary (rough) grinding of wood, when it is required to smooth out the irregularities of the sample.

End disks

The names speak for themselves. Such nozzles process the final parts of wooden blanks (cuts). Especially effective if you have to deal with angular (oblique) cuts.

Petal nozzles

The most used grinding devices for the grinder.

Nozzle for grinder for brushing wood

Many masters believe that metal brushes used to clean rust, oxides only of steel products. In refutation of this fact, brass wire products are popular in wood processing. Relatively not high price, increased resource during operation, make the brush a direct competitor of abrasive nozzles.

The main purpose is to remove the paintwork from the surface of the material. It should be understood that the top layer of paint can be removed by exposure to temperature, the brush is used when working in hard-to-reach places.

It is also possible to brush wood with a grinder with a brush. The process implies artificial aging surfaces in the manufacture of unique interior products. The surface is processed with soft particles of wood, irregularities and temporary rings stand out against the general background.

Rules for working with the tool

Any tool can be a serious hazard if the instructions for use are not followed. specific situation. Bulgarian for cutting wood in this sense is no exception.

Correct circle size.
Installing a wood disc for a grinder.
Select the appropriate operating mode for the machine.
Refusal to use damaged circles.
Use of personal protective equipment.
The nozzle size should be installed without problems under the protective cover of the machine.

If this does not work, do not remove the protection. When working on wood with an angle grinder, it is necessary to use only special circles on wood for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or a damaged tool.

In order to avoid the destruction of the disk on wood for the grinder, the speed of the grinder must correspond to that indicated on the surface of the circle. Before starting work, it is worth checking the wood disk for defects and damage.

If they are present, then it becomes dangerous to use. When working with the tool, eye and hand protection must be used. It would be best to use tight overalls.

Brush cord. These tools are ideal for rough wood sanding. The possibility of successful leveling of wood is assumed, with giving the optimal shape to the product.
End discs allow easy turning of workpieces. In most cases, such work is required for bevel cuts. The operation of the end disk resembles the interaction of the workpiece with the saw.
Flap sanding attachments are the most popular variant of the applied Supplies. The characteristic of the tool determines the possibility of processing various workpieces, including natural wood.
Felt circle - allows you to achieve minimal roughness, processed products. The basis is pressed wool, fine-haired, semi-coarse-haired and coarse-haired. Felt working tool allows not only to carry out quality processing wood, but also to give a perfectly smooth surface, comparable to a mirror.
A wheel for a grinder designed for grinding is often compared with a disc of the same name. It is important to note that the Velcro circle is a versatile tool with a wide range of applications.
Various woodworking tools certain tasks, but grinding wheel sometimes surprises with its versatility and high level efficiency.
The chain disc for wood is one of the most productive, but rough ways of processing natural material.

When choosing equipment, it is desirable to take into account not only the diameter, but also each accompanying informative designation. The inscriptions will allow you to determine the purpose of the tool and follow the recommendations during operation. Marking discs, circles and nozzles for grinders is a guarantee of a successful result.

A modern grinder is a convenient and effective tool. For high-quality work, special nozzles and discs are required to effectively process wood, metal and any other material of interest.

Safety rules at work

The use of angle grinders for wood processing requires a serious approach. Wrong work with a grinder can lead to injury, so before using it, experts advise you to pay attention to some rules for operating the device.

For example, before replacing one nozzle with another, you need to disconnect the angle grinder from the network. How to change the disk on the grinder? To answer this question, it is necessary to determine the type of circle. Some products are installed without removing the main nozzle. However, in most cases, it is required to unscrew the flange holding the element.

Note! In no case should you remove the casing, which is used for protection, from the grinder. In the event of a wheel breakage, this element will protect your face and other parts of the body from injury from splinters.

Processing wood material using angle grinders should be carried out with protective gloves. Sawing and cutting discs for wood are best used on medium (in terms of power) devices.

This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.

For sawing logs and boards, it is recommended to use nozzles that have fine teeth. The smaller their dimensions, the less effort will be required to cut. Among other things, it reduces the likelihood that hard wood fibers will meet in the path of the disc.

Any Bulgarian without fail must be equipped with a speed regulator, which must be moved to the minimum position. When working with cutting discs for a grinder, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.

Angle grinder can be used for wood processing, however, before use, you should study technical features various nozzles. Products that are used for grinding and polishing do not carry any danger and are easy to use.

Blades for sawing wood material require careful selection. During operation, it is necessary to observe the safety regulations and not deviate from them.

The grinder, or angle grinder (angle grinder), is a very popular tool that is versatile. It is used in the execution of most construction works. Many people are interested in the question of whether it is possible to cut a tree with it. To process this material, it is necessary to choose the right wood disc for the grinder. There are many varieties of nozzles, differing in characteristics and purpose.

The range of nozzles for this tool is quite wide. Products are classified according to their purpose, depending on which 3 main groups of circles for angle grinders can be distinguished:

saw;
With diamond-coated;
abrasive.

Saw. They are similar to standard saws, but are made from other materials. The most common option is tungsten carbide discs. They are not suitable for woodworking.

Diamond coated. This group of circles for the grinder is the most extensive. The high popularity of diamond-coated nozzles is due to a wide operational spectrum. With the help of such circles, it is possible to process metal parts, as well as elements made of stone and concrete. For a tree, such disks are not used.

Note! The use of angle grinders requires compliance with certain rules. One of them states that you can't use circles. larger diameter than indicated in the device passport.

Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.

These products are differentiated by one more sign - dimensions. The modern market provides a wide selection of products, the dimensions of which vary from 115 to 230 mm. The 115 mm wood grinder disc is the most compact and is used for fast and accurate cutting of material. It is worth noting that the largest discs are not suitable for working with wooden surfaces.

Types of wood discs for angle grinders: design options

Many experts do not recommend using a grinder for cutting and processing wood. This is due to the principle of operation of the device and the characteristics of the material itself. However, the variety of discs for angle grinders is growing every year. They can be divided according to the features of the work into several types.

Circular saws. Such wood circles for grinders are used, as a rule, for more technologically advanced equipment, but many install them on angle grinders. They are divided into two types: large diameter soldered and more compact, without soldering.

Chain. Ideal for working with wood materials. Many people are interested in the question of whether it is possible to saw a tree with a grinder. There is no single answer to it, however, chain products are maximally adapted for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. Such a design has many advantages. This nozzle is most commonly used for smooth cutting boards. With it, you can process other materials: chipboard, fiberboard, plywood.

Saws with a small number of teeth. This kind of circles was invented specifically in order to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones - 4. This group also includes cutting discs for a 125 mm wood grinder. These products do their job well. They can be used to cut wood along and across the grain. In addition to standard functions, such discs are used to organize grooves in workpieces.

Segmental (material - tungsten carbide). Such products appeared relatively recently, but have already gained immense popularity. A distinctive feature of such products is the absence of teeth. The edge of the disk consists of segments that are characterized by high strength.

Useful information! With the help of a segment nozzle, you can work with wood of any strength and viscosity. It is highly safe and is able to withstand even metal inclusions present in some blanks (self-tapping screws, nails, etc.).

Chain saw blades for wood: application advantages

In this case, the saw circle is made using a chainsaw chain. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency. A chain drive on a tree for a grinder is also considered the safest. Using this attachment greatly reduces the chance of injury if the tool jams.

Wood saw blades for angle grinders with a chain are used for various kinds of work. With their help, you can remove tree branches, as well as cut boards of small thickness. The functionality of chain products allows them to be used as peeling tools. They do an excellent job of removing the bark.

With the help of a saw blade, you can make an even cut of parquet boards, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material to be processed with such a nozzle should be no more than 4 cm. Otherwise, the device is likely to overheat.

Cutting disc for wood for a grinder: features

For the manufacture of such products are used special material- tungsten carbide. This is explained by the following: when working with a grinder, there is a possibility that it will break out of your hands, so the material of the circle must have high strength characteristics. The use of tungsten carbide can significantly increase the safety of work, but the cost of such products is quite high.

Disks this type may have a different arrangement of teeth. A variety of types of products on this basis allows you to choose the most suitable nozzle for a particular situation. The shape and frequency of the teeth also play a very important role. The most common wheel size for working with wood is 125 mm. If you decide to choose the most versatile version of a cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.

Useful information! Wheels that have straight teeth are best for working with soft woods. Softwood boards are also processed using such nozzles.

These products may have teeth that resemble a trapezoid in shape. They are characterized by a wider operational scope and are used for cutting boards with an average density. With this wheel, you can cut the following materials:

USB plates;
wood fiber boards.

Saw blades for wood for this type of grinder have some design features, which are determined by their purpose. For example, during operation, products easily overheat, so they have special slots that can be empty or filled with copper. Such a measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots can be different, but not more than 2 mm. As for their depth, it does not exceed 20 mm.

Grinding disk for wood for a grinder: characteristics

Peeling discs for wood for grinders are also used to level the surface of the boards. Such circles are equipped with special spikes, which are placed on a flat plane. This feature is very useful, as it allows you to polish the boards from which the flooring is constructed.

Brushes are used to remove paint and varnish materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.

Note! For wooden parts, it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types of wood.

Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give the wood an unusual look, to artificially age it. However, with the help of a grinder with a peeling wire nozzle, only small volumes of wood can be processed. Thus, for brushing on an industrial scale, this element is not recommended.

Grinding and polishing discs for wood on a grinder

Grinding and polishing wood is carried out using special nozzles that are used for grinders. Such products include a metal base on which the grinding wheel is fixed. Fastening is usually done with Velcro.

To use such a wood attachment for a grinder, it is necessary to fix it with a key (open-end) on the tool shaft. Quite often, it is implemented complete with a special transition element, thanks to which it becomes possible to quickly attach to the drill chuck. In turn, polishing requires the use of a more gentle material. Therefore, nozzles of this type are equipped with felt discs. Their fixation is also carried out with Velcro.

Another option for a grinding wheel for a grinder is a petal one. Its design fully justifies its name. It consists of a large number of sandpaper petals, closely spaced to each other. If desired, you can select the desired paper grain, which allows you to process wood materials of varying degrees of density.

Despite the fact that the grinder is not considered the preferred tool for woodworking, sanding attachments are very common. It is worth noting that grinding in this way is not suitable for smooth surface treatment, since even the most gentle options for angle grinder discs leave small scratches on the wood. If you decide to perform this process as efficiently as possible, then experts recommend purchasing a special device - a grinder. Angle grinders are usually used for materials that will subsequently be painted with paint.

Grinding wheels for grinders on wood: rough grinding

Grinding wheels that are used for angle grinders differ in the material of manufacture, shape and operational purpose. The process of wood processing, as a rule, proceeds in two stages. First of all, rough grinding is performed, after which the material is subjected to finishing. For rough polishing, several types of nozzles are used:

peeling;
corsets;
end circles.

Sanding wood with a grinder using a peeling product is most often used to remove a layer of old paint. Sometimes nozzles of this type are used to remove varnish if it cannot be removed manually. Such circles can have a different relief, the characteristics of which determine the efficiency with which the product will function.

Brushes are used for sanding different types of wood. Products that belong to this group are classified according to their design, the direction of the wire bundles and their diameter. Depending on the rigidity, they are also divided into types. If necessary, there is the possibility of selecting the right tool, corresponding to a particular grinding option.

Useful information! For rough processing, a larger diameter wire is used.

End discs for grinding wood on a grinder are used when it is necessary to adjust the size of the part from the end. Often, such products are used for the usual alignment of the side surface with uneven cuts. The principle of operation of the end nozzle resembles the operation of a file. The difference in this case lies in the high efficiency of the angle grinder.

The use of grinding attachments greatly simplifies the processing of wooden blanks. Such products allow for the restoration old furniture, removing paints and varnishes from its surface.

Grinding discs for grinders: flap discs

After rough processing, it may be necessary fine finish. Of course, if the wood is to be further painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases, finishing is necessary action. To perform grinding, you can use a common nozzle - a petal circle.

The design of the petal disc model, as mentioned above, includes sheets of sandpaper that have a trapezoidal shape. Their grain size is selected depending on the type of wood and the specifics of the work. grinding disc on a tree of this kind is one of the most common. It ensures gentle handling of the material and is characterized by a high degree of safety. It is almost impossible to get injured using this disc.

From size abrasive coating on the petals depends on the efficiency and speed of wood processing, as well as its appearance. For maximum smoothness, it is customary to use fine-grained products. Experts recommend using several of these grinding wheels on wood at once. This will make it possible to quickly carry out a rough cleaning, and then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.

The use of such a nozzle requires a certain skill from a person. Therefore, before using the petal circle, it is recommended to practice on wooden parts.

Grinding wheel for grinders: soft processing and polishing

For soft grinding, special discs are used, which appeared on the market not so long ago - just a few years ago. Such circles are characterized by a high degree of functionality and can have different grain sizes.

Useful information! Unlike petal nozzles abrasive particles are fixed with Velcro on the surface of the disc, and not on its end part.

Grinding disc for wood grinder of this type has one advantage - ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so using such discs is quite convenient. Sticky nozzles can be easily purchased on the construction market or ordered on the Internet. Choice desired grit in this case is not a problem. With the help of such devices, you can bring the wooden surface to the desired state.

Polishing, which is carried out after grinding, can be carried out using special felt wheels. Such nozzles provide maximum smoothness of the work surface, which is difficult to achieve using other tools. A large number of revolutions of the angle grinder contributes to uniform polishing of the wood.

Felt discs for the grinder include wool (tightly pressed), which may have various characteristics(depending on need). On the modern market you can find various options for nozzles in their composition:

fine-haired;
semi-coarse;
coarse-haired.

Woodworking attachments are different high efficiency and quality. Sequential use of these disks allows you to achieve incredible results. The wood surface after their use can be compared with a mirror.

Safety rules when working with a wood grinder

The use of angle grinders for wood processing requires a serious approach. Improper work with the grinder can lead to injury, so before using it, experts advise you to pay attention to some rules for operating the device. For example, before replacing one nozzle with another, you need to disconnect the angle grinder from the network. How to change the disk on the grinder? To answer this question, it is necessary to determine the type of circle. Some products are installed without removing the main nozzle. However, in most cases, it is required to unscrew the flange holding the element.

Note! In no case should you remove the casing, which is used for protection, from the grinder. In the event of a wheel breakage, this element will protect your face and other parts of the body from injury from splinters.

Processing wood material using angle grinders should be carried out with protective gloves. Sawing and cutting discs for wood are best used on medium (in terms of power) devices. This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.

Any angle grinder must be equipped with a speed controller, which must be moved to the minimum position. When working with cutting discs for a grinder, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.

Angle grinder can be used for wood processing, however, before starting operation, you should study the technical features of various nozzles. Products that are used for grinding and polishing do not carry any danger and are easy to use. Blades for sawing wood material require careful selection. During operation, it is necessary to observe the safety regulations and not deviate from them.

Bulgarian, being a universal tool for home master or a professional, is used when performing a variety of operations for cutting materials, grinding, peeling various surfaces etc. Sooner or later, every owner of this tool asks the question: is it possible to work on wood with a grinder, and what nozzles are needed for this?

The only operations with wood that can be performed with an angle grinder (angle grinder) without fear are grinding and peeling, and then using special nozzles. Cutting wood of course will work, but it is strictly forbidden! The Internet is full of shocking photos showing what the use of an angle grinder as a cutting tool for wood leads to.

The main arguments that can be made against the use of angle grinders for sawing are as follows.

This machine is not designed for sawing wood.
Since the wood has a viscous and soft structure, the saw blade can jam in it. As a result, the grinder is often pulls out of hand, and it flies in an unpredictable direction (in the leg, on the arms, in the stomach, etc.), causing deep wounds to a person or amputation of fingers. Even fatal cases have been documented.
When cutting wood, it happens very quickly saw blade heating which causes it to lose strength. At the slightest distortion or excessive pressure, it can fly apart. Since the spindle speed of the angle grinder is high, the fragments of the tool scatter at the speed of shrapnel and enter deeply under the skin of a person. The user is lucky if the fragments do not fly into the head or eyes.
Despite the danger of using saw blades with teeth, some angle grinder users ignore this fact and continue to install circular saw blades with large teeth or improved carbide tips. If, when cutting wood, a hard knot or the remainder of a nail gets into it, then the tooth or solder breaks off, clings to the next saw tooth and is thrown out at the speed of a bullet. The consequences can only be guessed at.
Ignoring all the warnings, angle grinder users install a circular saw of a larger diameter on the machine than the protective cover. This is the most dangerous option for using angle grinders.

Based on the foregoing, sawing a tree with an angle grinder is possible only at your own peril and risk, and then if this is a single or infrequent operation.

If you have to cut a tree constantly, then it is better to purchase a special machine for this purpose, or use a jigsaw. In extreme cases, the grinder can be used as a drive and make a circular out of it, fixing the apparatus rigidly on the frame.

What are the circles for cutting wood

Despite the danger of using angle grinders for cutting wood, tool manufacturers still produce saw blades for it.

Circular saws

The photo below shows "dangerous" saw blade for the grinder, although its diameter corresponds to the protective casing of the grinder with a maximum working tool of 180 mm. There are saws with soldering and a smaller diameter.

In the next photo you can see a less dangerous version of the circular saw. It provides protection against jamming, and it is implemented due to a small set of teeth in different directions.

Chain saws

A saw blade made using a chainsaw chain reduces the risk of injury when the tool jams. This nozzle is designed in such a way that the chain fixed on the inner disk (base) has non-fixed landing.

If the chain is jammed in the material being processed, the base continues to rotate, and the tool does not pull out of the hands.

These chain discs for the grinder have many modifications, and with their help you can cut branches in the garden, as well as use them for rough cutting of thin boards.

In addition to cutting chain disc can be used and how rough, for example, for removing the bark, as well as for cutting cups in log cabins and modeling.

Saws with few teeth

Also for the grinder, in order to increase the safety of working with wood, tool manufacturers produce cutting discs with a small number of teeth.

Small diameter discs can have 3 teeth, and large diameter discs can have 4, as shown in the following photo.

These discs for grinders remarkably cut wood both along the fibers and across. In addition, with the help of a saw blade, you can cut grooves, make various cuts and spikes in the workpiece. But when working with an angle grinder, one rule should be followed: you need to install a cutting disc of such a diameter on the grinder, for the use of which it is designed by the manufacturer, that is, do not exceed its dimensions. Circles of smaller diameter can be set.

Tungsten Carbide Discs

Tungsten carbide discs for angle grinders have appeared on the market not so long ago and have made a kind of revolution in the field of woodworking.

The universal disc has no teeth. Instead of the latter, there are segments around the circumference of the nozzle. cutting disc similar in appearance to diamond circle for cutting concrete. With the help of a tungsten carbide wheel for an angle grinder, you can very easily cut wood of any hardness and viscosity. In addition, he is not afraid of nails, screws and other metal inclusions that may be in the workpiece on his way.

This is the safest wood saw blade for an angle grinder.

Its price on the Internet is about 700 rubles. But if you take into account possible consequences use of circular saws, this is a low price for safety.

Wood sanding attachments

For wood processing, in addition to cutting wheels, there are nozzles specially designed for installation on angle grinders, with which you can peel, grind, brush and mill wooden surfaces.

Peeling nozzles

If you need to remove a layer of paint or other coating from a wooden surface, you can install a peeling nozzle on the grinder. There are a wide variety of nozzles on the market for peeling works. They differ in shape, design, and in the types of work that can be performed with this tool.

The photo below shows disc nozzles. with spikes or chips, with which you can easily remove the top layer of wood, grind the end of the board, etc.

The next cutter, due to the fact that the spikes on it are located on a flat plane, allows leveling various wooden surfaces. For example, if 2 boards on the floor at the end connection are on different height. With this nozzle, the defect is easily eliminated, and the boards are joined in the same plane.

There are also peeling nozzles twisted wire. They can be made in the form of a metal cup with a wire inserted into it.

Or in the form of a disk with coils of wire clamped in its central part.

These brushes are used if you need to quickly peel old paint from a wooden surface or rust and paint from metal.

The next photo shows a brush with a smaller diameter wire, and it is used for finer roughing work on wood and metal.

In addition to stripping, this cork brush is often used for brushing wood, that is, giving it the effect of aging. If this effect is to be applied on large surfaces, in professional field, then for brushing it is better to use special manual machines with wide brushes.

Sanding and polishing tips

For grinding various surfaces, including wood, there is a special nozzle for angle grinders on sale, consisting of a metal base, on which it is fixed with Velcro emery grinding wheel. The nozzle is screwed onto the grinder shaft and tightened with an open-end wrench.

Often it is equipped with an adapter for fixing it in a drill or drilling machine chuck.

The grinding wheel is not used for polishing surfaces. Instead, they are installed on the nozzle felt discs that are fastened with Velcro.

It is also often used for sanding wooden surfaces. petal emery wheel. It is called from so because it consists of many petals fixed on its plane, made of sandpaper. The grit size of the latter can be selected based on the requirements for the treated surface. For rough sanding, emery with a large grain is suitable, and for finishing - vice versa.

The better to grind a tree - with a grinder or a grinder - depends on what you are going to prepare the wooden surface for. If under application regular paint, you can use a grinding wheel. If for varnishing, then the grinding wheel installed on the grinder cannot be used, since it will give small radial scratches on the surface of the wood, which will clearly appear after applying the varnish. In this case, longitudinal grinding is used for grinding. belt grinder(the emery belt moves longitudinally) or vibrating, where the same emery wheels are used.

Safety measures when working with a wood grinder

If you still decide to use the grinder as a tool for cutting wood, then you should remember some safety measures that cannot be ignored.

Before installing the tool on the angle grinder, it must be disconnected from the power supply.
Under no circumstances do not remove the protective cover from the angle grinder. This is the only barrier between the circular saw and your skin. In some cases, it will be able to protect your face from flying tool fragments.
When working with a grinder on wood and not only the use of protective gloves is a must.
Do not use large and powerful angle grinders for sawing wood. If the saw jams, you will not be able to hold the tool in your hands.
Do not use saw blades with large teeth, as the likelihood of them catching on hard wood fibers increases significantly and, accordingly, the likelihood of pulling the tool out of hand increases.
LBM must have speed controller to be reduced to a minimum. If there is no regulator in the device, then it is better not to risk your health. In extreme cases, the regulator can be made by hand, and installed in an extension cord outlet.
The grinder should be kept during sawing strictly at a right angle. From any slightest distortion, the circular saw can collapse.
In no case should you fix the start button of the device, because in an emergency you will not be able to stop the tool and minimize injuries.

The Bulgarian is associated with an ordinary user with a tool for metal, concrete, brick. This is not the whole area where angle grinders are used. She can work with wood. There are special discs for the grinder. For sawing, milling, grinding wooden blanks, several types of cutting wheels are used. Each is designed to perform a narrow-profile task. Universal variant does not exist.

Saw blades are classified by diameter. This parameter is taken into account when selecting a nozzle for a specific model of an angle grinder. If the diameter of the disc is larger than the permissible one, then working with the tool is possible only after removing the protective cover, and this is a gross violation of safety regulations. To avoid problems, cut-off wheels are available in several unified sizes:

115 mm - sanding wood in hard to reach places
125 mm - milling, grinding, debark
150 mm - sawing boards
180 mm - sawing thick boards
230 mm - processing of massive workpieces. An angle grinder with a disk of this diameter is difficult to hold in your hands

Depending on the design, the wood grinder disc is used in several operations:

cutting
Cleanup
Milling
Grinding

Let's consider each in more detail, and also determine the nozzles for each type of work.

cutting

A wood grinder disc is rarely used directly in sawing. With it, you can process boards up to 40 mm thick, while observing safety regulations. There are two types of saw blades that can be used to cut a board:

Hybrid. It consists of a round metal base and a chain around it from a chainsaw. The nozzle is used when working with thin boards, with small cuts along the length.
Disc for circular or hand saw. This is a round saw element with teeth of different sizes located along its outer edge. The pitch and size of the tooth affect its characteristics. The larger it is, the more aggressive the sawing. The smaller, the neater the cut.

A standard circle for a circular or hand saw is cast from solid steel. It is designed for installation in a stationary machine with a hard seat. The angle grinder works at lower speeds, the disc constantly vibrates. This can lead to its destruction, as well as injury to the direct performer of the work and others. Therefore, this type of work is not always safe.

Cleanup

This is a rough job with wood, for which a wood grinder disc is suitable. There are two types of factory-made nozzles for this type of work.

The disk is a planer. Practical attachment for the primary processing of logs and ends of irregular boards. It is massive, durable, equipped with three knives. With its help, the tree is cleared of bark. For work, it is not necessary to install a protective cover, since the thick cutting wheel will not collapse.
Peeling. It consists of a metal base and a chain for a chainsaw, which trims its outer part. This structure allows you to perform a rough cleaning of wooden blanks from the bark, to even out cracks and chips. The grinding chain wheel is suitable for cutting wood.

Milling

It is carried out with an angle grinder with nozzles for wood. Milling wheels in the workpiece cut grooves of different widths. The size depends on the thickness of the nozzle. A perfectly even cut, like on a machine, is over. But cutting out a simple landing socket or groove for a tongue will not be a particular problem.

There are solid and compound nozzles for milling. Compound circles make a wider cut.

Grinding

This is a finishing treatment of wood, designed to remove small bumps and roughness. There are several types of nozzles:

Cord brush. The working surface of the relief structure for deep, rough processing of wood. Cordbrush "bites" into the base, smoothing out bumps and chips.
End disk. Shaped like a bowl. The working surface is only a narrow strip on the outside of the saw blade. This shape allows you to process end angle cuts, as well as hard-to-reach areas.
Petal nozzles for grinding. The most common type for finishing. It consists of a steel base glued with abrasive material. The depth and quality of sanding depends on the grain size of the sandpaper. The smaller it is, the smoother the surface will be at the output.

There are two versions. The first is a disk glued with pieces of sandpaper in the shape of a trapezoid. Each next petal is overlapped. With such a working surface it is effective to process wood. She is slowly fading away. The second is a flap disk, where the abrasive material is located radially. Suitable for processing workpieces in hard-to-reach places.

Velcro grinding wheel. It is designed for repeated use. Only the working surface of sandpaper, which is attached to the base with Velcro, changes. Stores sell sandpaper with different size grains. This allows you to use the nozzle, both for rough and fine grinding.

Rules for working with angle grinders

Works are carried out only in goggles and gloves. During coarse cleaning wood is better to cover the whole face.
It is forbidden to remove the protective cover from the angle grinder.
Work is done by holding the tool with both hands.
It is forbidden to use a saw blade with a larger diameter than indicated in the technical documentation for the tool.
While working with the tool, it is recommended to lean on both feet.

Firms - manufacturers

There are budget cutting wheels Hitachi, Makita, Luga. They grind faster, vibrate more than more expensive ones. The quality of the surface treatment differs from the result of more expensive analogues. Professionals choose Kronenflex saw blades from Klingspor or Bosch. They grind more slowly, practically do not vibrate. Less likely to be destroyed by improper use.

Angle grinder is a very useful tool that can be used in various industries. It is due to its versatility that it has become widespread both at industrial facilities and at the household level.

Types of nozzles for wood

As a tool for woodcarving, only angle grinders with speed control are suitable. Since the main purpose of the grinder is the grinding of homogeneous materials, then to the processing of a heterogeneous structure wooden materials must be approached very carefully.

The following types of circles for wood can be distinguished:

Wood saw for grinder
Cutting discs
planers
Grinding

Each of these parts must be used for its intended purpose.

saw blades

A saw blade for wood for a grinder consists of a metal circle with a chain attached to the edge. The design of special sawing tools is similar to those used for chainsaws. But saw blades are made of tungsten carbide. When a disk for a grinder on a tree hits a solid obstacle in the wood - knots, resin, metal, its base rotates without breaking the chain. With chain nozzles, it is quite easy to clean the logs from knots and bark, to give them the necessary initial shape.

Cutting discs

Various manufacturers also produce cutting wheels for wood specifically for angle grinders, for example, the Bosch cutting wheel. Their design is significantly different from the design of discs for circular saws. Usually they have side teeth that protect the nozzle from jamming. Cutting tools differ in the number and shape of teeth:

bevelled;
straight;
in the form of a trapezoid.

The first version of the shape of the teeth is considered universal. It is suitable for all types of wood with small amounts of work. When sawing wood from soft varieties, it is quite possible to use discs for a grinder on wood with a straight tooth. Trapezoidal teeth are capable of processing fairly hard wood products: chipboard, fiberboard, OSB boards.

In addition, cut-off wheels vary in diameter. The minimum size is 115x22 mm. The most commonly used circles with a diameter of 125 mm, they are universal and suitable for a wide range of jobs. The maximum possible size is 230 mm. But the latter option is undesirable to use when working with wood, as the likelihood of injury increases. Depending on the size chosen, the depth of cut in the wood will also be different.

Disks - planers for grinders

It is possible to use the angle grinder as a planer. For this, special circles are used - planers. Work with such nozzles is allowed without a protective casing, since solid discs are not destroyed. Many brands of wheels can be sharpened repeatedly. Before use, an additional handle must be installed on the angle grinder to more securely hold the tool with both hands.

Grinding discs

This type of circles allows you to use the machine for its intended purpose. For finishing and polishing wooden surfaces, various types of nozzles can be used:

cord brushes;
end circles;
petal nozzles;
emery circles;
cutting nozzles.

Rough processing of wood is carried out with the help of special cord brushes. End discs are designed to level the edges of parts, which is often required when miter sawing workpieces. They make a great file replacement.

The widest range of grinding attachments is for flap wheels. Depending on the size of the abrasive grain, the surface of the wood can be cleaned with varying degrees of polishing. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved. The system of trapezoidal petals, which are stacked with a three-quarter overlap on each other, wears rather slowly. If the relief surface of a wooden product is complex, then petal discs with a radial arrangement of abrasive strips are used.

The use of sandpaper or sandpaper on a special nozzle allows you to grind fairly large areas of wooden surfaces. The ability to quickly change the sanding cover makes these tips versatile.

When removing old paint and varnish coatings, peeling nozzles are often used. As a rule, this is a wire brush attached to a metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for fixing the bristles on the perimeter of the disc.

When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, they must be cleaned to healthy wood.

Universal wood discs for grinder Graff Speedcutter

Wood disc for grinder Graff Speedcutter is a three-tooth circular saw that is designed for high-speed angle grinders. It is used in models with a maximum rotation speed of 12.2 thousand revolutions per minute.

The three carbide teeth are made of tungsten carbide and set at a 5° angle to the steel base of the tool. Thanks to this design and the special shape of each tooth, the cut surface is very clean and even. A disc is being made for the Graff Speedcutter grinder with a size of 125x22.23x3 mm. The cutting width of the wood is 3.8 mm.

Designed Graff Speedcutter circles for artistic wood carving, cleaning and sanding various types of wood. They are also used when cutting and selecting grooves in wood, its transverse cutting and longitudinal cutting. It is possible to use such nozzles when processing parts made of aerated concrete and gas silicate, fiberboard, chipboard, laminate, drywall.

Rules for working with the tool

Any tool can pose a serious danger if the rules of the instructions for using it in a particular situation are not followed. Bulgarian for cutting wood in this sense is no exception. The main points that are necessary when working with disks for an angle grinder - angle grinder on wood:

Choosing the right circle size
Installing a wood disk for a grinder
Selecting the appropriate operating mode for the machine
Refusal to use damaged circles
Use of personal protective equipment

The nozzle size should be installed without problems under the protective cover of the machine. If this does not work, do not remove the protection. When working on wood with an angle grinder, it is necessary to use only special circles on wood for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or a damaged tool. In order to avoid the destruction of the disk on wood for the grinder, the speed of the grinder must correspond to that indicated on the surface of the circle. Before starting work, it is worth checking the wood disk for defects and damage. If they are present, then it becomes dangerous to use. When working with the tool, eye and hand protection must be used. It would be best to use tight overalls.
