Saw blades for wood for grinders. Grinding disc for a grinder on wood: types and rules for choosing a chain disc for a grinder

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 angle model. grinder. If the disc diameter is greater than the allowable one, then working with the tool is possible only after removing the protective cover, and this gross violation safety regulations. To avoid problems, cutting wheels 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 saw blades, with which you can cut the 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. Peeling chain circle suitable for cutting wood.

Milling

It is carried out with an angle grinder with nozzles for wood. Milling wheels cut grooves in the workpiece 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. Work surface - only a narrow strip with outside saw circle. 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. Depth and quality of grinding depend on the grain size 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 changes working surface from sandpaper, which is attached to the base with Velcro. 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

Work is carried out only in protective glasses 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.
Do not use a saw blade larger diameter than indicated in technical documentation to the instrument.
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.

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 a 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 - this 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 circles. 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.

the work of the angle grinder

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 funds protection.

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

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. Design of special saw tools similar to those used on 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 must be within 2 mm.
The depth of the cuts made can be within 20 mm.
Cutouts can be empty or filled with copper.

With help saw blade on wood for a grinder you can decide quite a large number of various tasks related to construction repair work, production of furniture 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 by an angle grinder of an 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
Purpose	Saw
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.

chain disc on wood for the 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.

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. Minimum size- 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 technological process provides work with coniferous and soft breeds of wood.
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 the diameter and, accordingly, the depth of cut, but also by the 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 softwood, 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 align the edges of parts, which is often required for oblique cuts of 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 flap discs with a radial arrangement of abrasive strips are used.

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 craftsmen believe that metal brushes are used to clean rust, oxides only steel products. In refutation of this fact, brass wire products are popular in wood processing. Relatively low 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 upper layer 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 involves the artificial aging of 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 grinding tree. 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 universal tool, which has a wide range of applications.
Different tools for working wood perform certain tasks, but the 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 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. 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.

Treatment wood material with using angle grinders must be done 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. While working with cutting discs for an angle grinder it is very important to observe 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.

Wood is a specific heterogeneous material that requires special wheels to work with. Discs for grinders for metal are categorically not suitable for cutting wood! Otherwise, the disk may be destroyed during operation.

The saw blade for wood for a grinder is the same as for a circular saw, but of a smaller diameter. In most cases, discs with a diameter of 115 mm and 125 mm are used, which can be bought in our online store.

Attention! Working with a saw blade is extremely dangerous and requires skill with an angle grinder and great care. When sawing, it is possible for the blade to jam in the wood, which will lead to the tool being pulled out of your hands and serious injury. It is categorically impossible to cut wood with a grinder "on weight". The tool must be securely fixed on the table.

Choosing a saw blade for a wood grinder

When choosing a saw blade for wood, pay attention to the shape of its teeth, which can be alternately beveled, straight and trapezoidal. In our online store you can buy wood circles for a grinder with variable beveled teeth with a diameter of 115 and 125 mm. They are suitable not only for sawing wood, but also for cutting aluminum and laminate.

Another factor to pay attention to is the number of teeth on the disc. The higher the tooth frequency, the cleaner the cut will be.

What is a "grinder" at the present time, even a schoolboy knows - this is an angle grinder designed to work with metal blanks by using special cutting and grinding wheels. The fact that such an electric tool can be used for woodworking is not known to everyone, but only to professionals, so this article is intended to fill this gap in the information available to ordinary users. Disc for a grinder on wood - types, General characteristics and standard sizes, as well as safety measures for use and an overview of prices for popular models- this is the topic of this article of the editorial site

Depending on the type of disks used, the "grinder" in skillful hands can be used on various stages work with wooden blanks: from sawing to grinding

"Bulgarian" was not originally intended for sawing wood, especially for workpieces of considerable thickness and wood hard rock. This is due design features this type of tool and associated with such dangers of use:

when the saw blade is jammed, it is difficult to hold the angle grinder in the hands, which can lead to injury;

Important! Jamming of the saw blade when using a "grinder" for sawing wooden blanks is the most common problem in this type of work, which is due to the softness and viscosity of the wood.

uneven wood structure due to knots can damage the saw blade being used and injure the user.

Despite the potential danger of using an angle grinder as a tool for sawing wood products, manufacturers of consumables, which include grinder discs, produce similar products.

Expert point of view

Ask a Question

“For processing workpieces of considerable thickness and with professional use it is most correct to use a tool originally designed for sawing wood, which are circular and Circular Saw».

The main and most common uses of the “grinder” when working with wood are: its peeling, grinding and polishing, for which manufacturers produce special types of discs.

General characteristics of discs for "grinder" depending on the type

Discs designed for different types of use differ in their design and materials used in their manufacture. In this connection, different types similar products, the general characteristics vary, which requires their separate consideration.

Cutting models

circular– considered “dangerous” saw blades;
chain- are made using links designed for chain saws;
with few teeth- are the safest, compared with circular analogues;
tungsten carbide- the safest type of such equipment.

Note! Circular discs come in two modifications: this is a "dangerous" and "less dangerous" option. Distinctive feature models of the "less dangerous" type is the presence of anti-jamming provided by the setting of the teeth.

Chain modifications are less dangerous when used, as they their design provides for a non-fixed fit saw chain on the surface of the disk.

“When the saw chain is jammed during its use, the disk attached to the angle grinder continues to rotate, the tool does not break out of the hands, allowing it to be emergency stopped.”

Discs with a small number of teeth are of two types:

with 3 teeth- used with small "grinders" with a diameter of up to 150 mm;
with 4 teeth- are used on "grinders" of a large size with a diameter of 230 mm.

A distinctive feature of models made of tungsten carbide is the absence of teeth on the cutting surface of the product. Segments located along the circumference of the disc act as a cutting element.

Important! Tungsten carbide models are able to cut various hardware(nails, self-tapping screws, etc.), which can be in the workpiece without damaging the cutting elements and their integrity.

Grinding discs

For peeling wooden products, manufacturers produce several types of nozzles that differ in design and types of materials used in their manufacture.

By design, such nozzles can be made in the form of:

a disk with spikes or crumbs applied to its surface;
a glass with cutting elements made of twisted wire inserted along its circumference;
disk with wire coils mounted on its surface.

“Scraping attachments are used to remove paint and other coatings applied to a wood surface, as well as to roughen a smoothed wood surface.”

Models for grinding and polishing

To perform grinding and polishing, there are special nozzles used both for wood and for other materials (metal, plastic, glass, etc.).

Nozzles used for such purposes are of two types:

the basis of the design is a metal base, fixed on the angle grinder shaft, and circles made of sandpaper of different grain sizes or polishing materials (felt, cloth, etc.), which, in turn, are attached to the base with Velcro;
petal emery wheel.

Standard disc sizes for "Bulgarian"

In the production of discs for angle grinders, manufacturers operating in our country produce their products in accordance with the following regulatory documents:

Angle grinder - very useful tool, which can be used in various fields of production. 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 special form 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.
