Chain drive on the grinder. How to choose a wood saw blade for an angle grinder? Grinding wheels for grinders on wood: rough grinding

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, the processing of the heterogeneous structure of 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. Design of special saw tools similar to those used on 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 differs significantly from the design of disks for circular saw. Usually they have side teeth that protect the nozzle from jamming. Differ cutting tools by 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 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.

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 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 relief surface of a wooden product is complex, then petal discs with a radial arrangement of abrasive strips are used.

Usage sandpaper or skins on a special nozzle allows you to grind quite large areas 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. 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.

Universal wood discs for grinder Graff Speedcutter

Wood disc for grinder Graff Speedcutter- this is Circular Saw with three teeth, which is intended 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 grinding various breeds tree. 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 be a serious hazard if the instructions for use are not followed. specific situation. 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 funds personal protection

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.

If it is necessary to carry out woodworking work, many people think about using a grinder as the main tool for work. In general, an angle grinder can be used, but its scope is limited. So, with the help of angle grinders, it is possible to carry out grinding, polishing and peeling of wood. Now special nozzles used when working with wood have become very popular, but not all of them can be used.

To understand whether handle wood grinder, you need to study the device and the types of nozzles existing for it and what characteristics they have. So, any circle has its own diameter.

The most compact is 115 mm, which is more often used for grinding and simple processing. The most common diameter is 125 mm, it is not heavy, it is used for grinding and cutting workpieces. Nozzles from 180 to 230 mm are used in the tool high power and are more often used in professional construction.

Types of disks are usually divided according to production technology and purpose (for metal, for stone).

Abrasive coated discs

Is universal disc- with his help can cut and grind both metal and stone. abrasive coating consists of corundum, electrocorundum or silicon carbide. Among the advantages of these circles are:

Cooling of consumables due to the porous structure of the disk.
During the work is not blunted.
Wide range and low cost.

The disadvantages include:

The formation of a large sheaf of sparks during work.
Strong burnt smell when cutting workpieces.
Rapid wear.

The most common version of the attachment for the grinder, which is used when working with stone and metal. There are three types of diamond discs:

Solid. Solid disc with continuous rim diamond coating. Designed for wet metal cutting.
Segmented, in which the cutting edge is divided into segments. Used for dry cutting.
Turbodisk with cutting edge in the form of a wave, in connection with which the contact area with the workpiece is reduced, which ensures the natural cooling of the wheel. Can be used for both wet and dry cutting.

The diamond blade is wear resistant with very precise cut line, does not smell of burning, and the number of sparks during operation is minimal. Disadvantages include relatively high cost and low heat resistance.

The use of diamond and abrasive discs when working with wood is fraught with breakage of the grinder, and replacing them with circles used in circular saws or milling cutters is prohibited - these nozzles are designed for low speeds. The use of such circles in angle grinders can lead to breakage of the tool itself, so a new type of nozzle is becoming increasingly popular: a cutting disc for wood for a grinder, the use of which is theoretically allowed in woodworking.

Wood discs for angle grinders

Visually, they resemble a cutter, there are also discs with a chain surface. The most standard is saw blade on wood for a grinder 125 mm in diameter, with an increase in diameter, the risk of injury and mutilation during work increases. The optimal thickness is 2 mm, and the cutouts should be rounded towards the shaft. There are three types cutting discs on wood for grinders, which differ in the shape of the teeth:

Trapezoidal fit for cutting chipboard medium density.
Variable beveled teeth are versatile and are well suited for occasional applications where material type and thickness are not known in advance.
Straight teeth are used for soft woods such as softwoods.

Wood sanding discs

For peeling work, a flap disc is used, working surface which consists of several strips of sandpaper of various grain sizes. This nozzle provides soft grinding, however, remember that you need to work with well-dried wood.

In addition to petal, the so-called sticky disk. It is a nozzle on which you can stick sanding paper of various grain sizes. The connection takes place with the help of a special adhesive paste applied both to the circle and to the sandpaper. Using a Velcro disc, you can process both wood and workpieces made of metal and stone.

There are special nozzles for brushing - the process artificial aging wood. They are brushes with metal, synthetic and sisal bristles, the choice of which depends on the stage of processing. So, metal brush suitable for primary peeling of the workpiece, synthetic bristle is intended for intermediate grinding, finishing polishing is performed with a sisal brush.

In conclusion, it should be noted that the angle grinder is not structurally intended for sawing wood and using carbide discs. There are special tools for this: circular saws, milling cutters. They have a lower speed, and the use of cutting discs for wood for grinders systematically leads to injuries, including those incompatible with life. It is possible to consider angle grinders as a tool when working with wood only in the case of grinding work.

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 under standard sizes Bulgarians. 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 options: 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.
Use personal protective equipment.

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.

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 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.

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 the help of a saw blade for wood for an angle grinder, you can solve 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 a 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.

Rapide saw blades are made from high quality tool steel and are highly wear resistant. Carbide teeth this disk are equipped with tungsten carbide tips and have high-precision sharpening.

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 the seat of an 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 kinds cut - both for cross, and for 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.

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.

By using saw blade you can make a straight 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 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.

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.

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 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.

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.

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 works varying degrees of complexity. 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.

Use petal circle 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 discs

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 not high price, increased resource during operation, make the brush a direct competitor of abrasive nozzles.

The main purpose is to remove 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 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 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.

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. Work 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.
Various woodworking tools certain tasks, but the grinding wheel sometimes surprises with its versatility and high level of 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. 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 of 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 to do.

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 a 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.

Angle grinder is a universal device with which you can work with any material. Perform cutting, peeling and grinding operations. Among the people, she received the name Bulgarian. When handling the tool, you need to carefully select the circles. It depends on the size of the equipment, the rotational speed and the type of surface to be treated.

A variety of discs for grinders

The range of discs for angle grinders is great. When buying, you need to understand well what discs are for grinders. They differ depending on the work performed:

Characteristics and choice of circle

When choosing a circle for an angle grinder, you need to take into account what material will be worked with. In this regard, several factors are taken into account:

Sometimes there is a desire to install circular circle to Bulgarian. This cannot be done. The reasons are as follows:

Cutting disc for wood

The cutting disc for wood for grinders is made of high-strength alloy. When choosing, you need to be guided the following rules:

Hard wood requires the use of an variably beveled wheel.
For softwoods and softwoods, a straight tooth is used.
Medium-hard rocks lend themselves to cutting a trapezoidal tooth.

In progress circles are heating up. It is not always possible to cool them down. Therefore, slots are made from the side of the teeth to the axis. They are 2 mm wide and 20 mm deep. Sometimes they are filled with copper. expansion is compensated. This prevents deformation of the metal.

Rough stages of work

At the first stage, the blanks are peeling. To do this, there are nozzles on the grinder for working with wood:

Gentle discs for wood

These are nozzles universal type. They are used depending on the work performed:

Tool cutter features

The cutter as a nozzle for the grinder is allowed for use, but requires precautions. With its help, you can make grooves, roughly process the ends of the workpiece or saw it. In the process of work, its jamming is excluded, but you need to know at what speed it is allowed to use it. It is important to consider in which direction the cutter is rotated relative to the location of the angle grinder.

The surface quality will be somewhat different from working on milling machine. However, the necessary operations can be done.

Using a chainsaw chain

If put on chainsaw chain on disc, you can cut boards up to 40 mm. In doing so, care must be taken. To avoid injury, you must adhere to the rules:

Do not remove the protective cover. If it interferes with the installation, then the equipment cannot be used.
The RPM value is set according to the one indicated on the disk. Otherwise, the chain will jump off.
Work is carried out in protective glasses and gloves.

If it is necessary to work with wood, it is possible to use attachments for a grinder for wood processing. However, you must first read the instructions. Such work has its own characteristics. If you ignore them, you can easily get hurt.

Quite often, the grinder is used to process various types of material. Some sources claim that it is strictly forbidden to work with this power tool on wood, while others say that it is possible, but only taking into account some nuances. One way or another, an angle grinder is used in carpentry. Therefore, the question of using a wood cutter for a grinder remains relevant.

The saw blade with chain saw chain elements allows you to cut boards up to 40 mm thick, and it is important to be extra careful. Violation of the rules can lead to injury:

Protective covers on the tool must not be removed. With a large diameter discs that exceed the dimensions of the casing, the grinder cannot be used.
work corner grinder necessary in compliance with the speed indicated on the cutting tool. If they are exceeded, the chain may slip, which will lead to the scattering of its constituent parts.
Protective goggles and thick gloves are a must. It is also recommended to work in dense tarpaulin clothing.

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.

This ban also applies to diamond cutting discs for concrete. To work with wooden products they are not safe because they are not designed for that. The efficiency indicator from their use is quite low, considering the cost of disks. And also there is a possibility of charring the product and simply ruining it.

And most importantly, there is a possibility of such a disc jamming at the processing site, which will lead to the tool flying out of the hands and possible injury.

With such a disc for the grinder, which is shown in the figure below, you should work as carefully as possible when processing wooden materials. Its design provides for protection that prevents jamming of the side teeth, which contribute to the expansion of the cutting width. The disk has a diameter of 115 mm, and thanks to its dimensions it is possible to work with the protective cover installed.

Some home-grown "masters" practice fitting standard saw blades for a circular saw to an angle grinder. All work is done with protective covers removed. Often the ending of such experiments is rather tragic. Unfortunate masters receive serious injuries that threaten life.

But despite this, the construction markets are full of offers that allow you to purchase. Inexperienced craftsmen are convinced by sellers that when correct use there are no risks associated with such tools. All this is true, exactly until the moment when nothing bad happens.

No professional shops will ever sell a person a grinder disc that may also be suitable for working with a circular. For such sales, if the buyer is injured, the seller may be held criminally liable.

The list of the main reasons why the use of a circular saw to work with an angle grinder is unacceptable:

discs are designed to work at low speeds, the material of such a cutter is quite fragile. In the process of work, there is a possibility of the tool breaking into small pieces or the spalling of the teeth soldered on the disk, which fly off at great speed;
the wood has a rather viscous structure, in connection with this, the bite of the teeth occurs in an uneven way, which leads to vibrations and the mobility of the tool. This can lead to loss of control of the angle grinder and cause serious injury;
jamming of the discs occurs during the working process when processing wood, the tool can be pulled out of the hands. Please note that the included tool with a rotating disc is unpredictable.
uneven loads caused by working on a wooden surface can cause the power tool to overheat, resulting in breakage.

The best solution is to manufacture a stationary sawing machine, on which the grinder will be securely fixed. absolutely simple, you need to prepare only the main components for this equipment. But it is definitely worth it, you will not only reduce the time for processing products, but also protect yourself from bad consequences.

We carry out rough processing of wood with a grinder

But, despite the existing warnings, it seems possible to process a wooden blank with an angle grinder. This requires the use special nozzles which are manufactured in working conditions, and strict observance of safety regulations in the process of working with the tool.

Using planer discs for grinders

Roughing a log house involves the use of special discs that allow you to perform the function of a planer. This kind of wood processing using angle grinder considered one of the safest if you follow the operating instructions. The device is a good alternative to a carpenter's axe.

The nozzle is used without the installation of protective covers, since the fact that it can be destroyed during operation is completely excluded. You cannot use such a disk if it has an upward position.

When using the grinder, it is imperative to provide for the installation of a handle on it, which will allow you to hold the tool with both hands.

It is also necessary to have tight overalls and personal protective equipment that can protect open areas skin. When cleaning wood, you may encounter large chips that can easily injure the skin. One of the positive side effects from the use of such a power tool, ease in chopping chips or large sawdust, if any, is necessary for household needs.

Application of grinding discs

To remove the bark from a tree trunk, and give it a primary shape for blanks, a number of special peeling nozzles are used for corner grinder.

Thanks to this chain circle it is possible to clean the trunks from bark or small knots. And also the required shape is given to the blank material for further processing using more precision tool. Such devices can replace axes for carving bowls in logs for the construction of buildings from a wooden frame.

It is also possible to use this disc as a cutting wheel, but the resulting cut will be jagged and the material loss is too high due to the large thickness of the cut.

Using milling cutters on angle grinders for working with wood

After completing the roughing, you should proceed to the next step in the processing of wooden blanks - milling. For this purpose, some types of special nozzles are used.

The size of the abrasive on the discs can be completely different. Using this cutting tool should take into account its purpose. By means of such mills, it is easy to carry out giving of a final form to preparations. Some craftsmen using such nozzles perform finishing tree and at the same time the results from such work are quite good.

Almost similar types of discs are a mechanized rasp. They are considered relatively safe tools that do not require special precautions and compliance with certain conditions. You just need to take care of the protection of the eyes and respiratory organs.

If you need to perform the usual cutting of wood materials, then it is better to use simple circular, chain and reciprocating saws for this, and not a grinder. Also, the task can be effectively performed with an electric jigsaw.

It should be noted that an alternative to electric tools for sawing boards and logs is homemade equipment. Fabricate to run simple tasks quite simple, so it is not necessary to use dangerous and expensive tools for simple tasks.

Milling a tree with a grinder: which cutters can be used

It requires careful observance of security measures. Similar work with a cutter using an angle grinder belongs to the class of dangerous, but acceptable when correct execution relevant recommendations.

A cutter on a grinder for working with wood is used to make grooves, rough edge alignment, cut out bowls for log cabins, and even for sawing blanks. It is possible to use only those cutters that have a special design that excludes the process of jamming and tilting of the power tool due to the heterogeneity of the wood. When using it, it is recommended that you read the instructions without fail, in particular about sections with maximum revolutions and the direction of movement of the cutter in relation to the position of the angle grinder.

Milling attachments for angle grinders are not inferior in their range to attachments for manual milling devices. Naturally, it is almost impossible to achieve a similar quality of material processing with a grinder, but it is quite possible to make a selection of suitable nozzles in order to give a suitable shape to the product.
