Grinding disc for a wood grinder: types and selection rules. A wood cutting disc for a grinder: an indispensable assistant, or a dangerous device? Metal cutting disc for wood for grinders

It's like a fairy tale about a unicorn, everyone has heard about it, but no one has seen it with their own eyes. The public of construction forums and authors of similar articles on the Internet is divided into two camps. The former say that in their life they sawed more than one cubic meter of wood with a grinder, the latter give strong arguments in favor of the fact that after such work you can miss your fingers or limbs, or even worse. Is there a disc for a wood grinder and if so, what does it look like and is it safe to work with it?

The author of this article kindly asks you not to consider this material as a guide to action. An angle grinder is not designed to work with wood, even those manufacturers that produce discs and cutters for wood write on their official websites that it is extremely unsafe to cut wood with a grinder. But we all know that people rarely think about their health in the first place.

Cutting with an abrasive disc

Yes, it’s possible to cut a tree with a metal disc, to be honest, I myself, working at a construction site, have done it more than once. What can be said? Well, firstly, the speed of work with this method is low. Secondly, the smell of burnt wood even on outdoors within a radius of 10 meters you are provided. And thirdly, the thickness of the sawn board should not exceed four centimeters. It's not saying that abrasive disc is not a wood disc for a grinder, its main purpose is to cut metal. As for the pros, in my opinion it is: the absence of sawdust, and a smooth, even cut.

Circular saw blade and its improved counterpart

The vast Internet is full of video materials on how to turn a disk for a circular or diamond disc on concrete in a disk for working with wood. You can argue for a long time about whether it is worth doing or not? Even without considering himself helluva lot smart person, I would not conduct such experiments. And that's why:

disk circular saw not designed for high speeds, yes, it is carbide, but no less fragile. A single chipped tooth can pose a great danger to a person.
the edges of the toothed disc are not smooth, crashing into a tree, the grinder will vibrate and crash into the branches of the workpiece. this operation may cause the operator to lose control of the tool.
increased chance of a kickback

There is an adapted disc for a wood grinder on sale, the manufacturers claim that due to the shape of the tooth and the special expanders that are on the cutting part of the disc, all of the above concerns about tool jamming disappear. One of the manufacturers is the company Rotarex, in its assortment you can find both grinding and cutting discs for grinders. Below is an image of a circular disc and a grinder disc from Rotarex, which is universal. They can cut not only wood, but also aerated concrete.

Chain disk for wood grinder

At first glance, it may seem that this is a device for a horror movie, but judging by the reviews of the owners, this disc is safer than the analogues presented above. It is a solid circle, along the edges of which there is a chain from a chainsaw, everything is made of high-quality tool steel. The main purpose of such a disk: milling, modeling, stripping wood from bark and cutting cups in a log for log cabins. It is also possible to cut with such a disk, given that the width of the cut will be about eight millimeters, since the thickness chain disc is six millimeters. Speaking of diameters, there are 125 and 230 discs for sale. The service life of such a disc will be many times longer than that of others, since it can always be sharpened with a file. The price for them ranges from two to three thousand rubles, and even more will come out with delivery from another region.

Remember safety!

Whatever disc you work with and whatever material you cut, you should always remember that compliance with safety regulations can save you not only health, but also life. And before you get started, read the following points:

not work in state alcohol intoxication;
when working, use safety glasses and overalls;
never remove the protective cover;
it is forbidden to use the wrong cutting disc or a disk with some, even small, defects;
when working with a grinder, hold it with both hands;
the electrical cord must be at a distance from the rotating disk;
do not put the tool down until the blade comes to a complete stop.

There are a lot of ways to cut a tree, one of them is to make a cutting disc out of paper. How effective this is, of course, is up to you to judge, but note that this is one of the safest options.

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 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 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. 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 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 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. 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 seat angular grinder(Bulgarians). 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, Soft wood, 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. 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 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.

finishing

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 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.

Usage sandpaper or skins for 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.

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 work of 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.

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.

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 of 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 remove 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 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 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 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. It is assumed the possibility of successful leveling of wood, with the addition optimal shape 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 sanders are the most commonly used consumables. 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 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. 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.

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. 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.

An angle grinder, if you know and correctly use all its capabilities, is a truly universal device that lends itself to almost any material. And if we are talking about processing wood on a large scale, then the “grinder” is much more effective than manual abrasive tools and fixtures. The main thing is to choose the right nozzle. This article will help you understand their main modifications and specifics of application.

Rough cleaning of wood

planer disk

Such a nozzle almost completely replaces this hand tool.

An irreplaceable thing, if it is required, for example, to make a rough processing of a log - when erecting a log house, preparing fence supports, and so on.

Application Features:

In this case, the protective cover can be removed. Such a nozzle is one-piece, and its destruction does not occur. But protection from flying wood chips (glasses, tight clothing, gloves) is required.
It is allowed to work only with a “grinder”, in which a second handle is provided (or installed). The angle grinder must be held when roughing wood with both hands.

Peeling disc

The main purpose of such nozzles is to remove the bark from the wood, to trim the workpiece. If the "grinder" is in capable hands, then with such a device you can make a sample of the material. For example, if you need to cut a bowl. If erected log house, then an angle grinder with such a nozzle perfectly replaces a carpenter's ax.

In some cases peeling disc cutting can be done. True, the cut will be wide, and there will be a lot of waste (chips, sawdust).

Milling

Disks

These nozzles are available in various designs. The main difference between the devices is the size of the abrasive grains.

They are not much different from rasps in terms of specific application. The difference is only in the speed of execution technological operation. With certain skills, it is advisable to use these for finishing wood.

cutters

They are, and specially for wood. The assortment is significant, since nozzles of this type differ in the configuration, location and size of the teeth.

Purpose of cutters:

Selection of grooves.
Edge trimming.
Cup cutout.
Sawing (for wooden blanks of small section).

Application specifics:

When processing wood with such nozzles, it is forbidden to dismantle the protective cover.
Each product has instructions. It clearly indicates for what types of work this nozzle is intended, the recommended speed of the grinder, and so on.

wood sanding

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.

Such nozzles are applied sequentially, so several of them will be needed to process wood. Grinding begins with a disc with a "coarse" abrasive, and gradually the size of its grain must be reduced. Consequently, the devices in the process of working on the "grinder" periodically change.

grinding wheels

The most universal adaptation to the "Bulgarian". It alone is enough for varying degrees of grinding. The nozzle itself is a metal base on which circles with one grain or another are attached. They are easy to change, or as they wear out, or in the event of a transition to another area of work. Therefore, only circles and are consumable. The nozzle itself is used indefinitely.

Application specifics:

Wood grinding.
Parquet scraping.
Edge and end processing.
Cleaning wood before painting.

wood polishing

For these purposes, brushes, disks, circles are used. Their "working elements" can be made of sponge, felt, fine-grained "sandpaper" and a number of other materials.

The article provides examples of only the main types of nozzles for the grinder. There are a lot of products of this class, so it's easy to choose best option devices for processing any wood. The author hopes that the information provided will help the reader in this.

On a note!

Wood processing also means its cutting (sawing). Sometimes, in the manufacture of piece parts, it is necessary to adjust them at the installation site even before starting to grind the sample. Some "craftsmen" (and there are many of them among friends and on the Internet) are advised to use for such operations. It is strictly forbidden! Here are just the main reasons why this should not be done.

"Bulgarian" - a high-speed machine. And although the metal from which the cutting discs are made is durable, in this mode it does not withstand for a long time. More precisely, cutting edges(teeth), which are fixed by soldering. With intensive work, they fall off and scatter to the sides, and with great speed. The consequences are easy to predict.
Not all discs are suitable for installation on angle grinders in terms of size (primarily, outer diameter). So, you have to dismantle the protective cover. The same thing - you can forget about the safety of the employee.
The structure of wood (even hardwood) is quite loose. Therefore, it is highly likely that the saw blade may jam due to constant vibration. How the “Bulgarian” will behave in such a situation, given its power and speed, no one will undertake to predict. But the fact that it breaks out of hands quite easily is unequivocal.
Constant changes in the mode (for the same reason - the viscosity of the lumber) lead to a systematic overheating of the angle grinder engine. With this use, the "grinder" will not serve for a long time.

That is why wood processing with its help is carried out only superficially - rough sweep, grinding, brushing. And for cutting, you should use sawing tools and mechanisms (hacksaw, circular saw, electric / jigsaw, and so on).

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.

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

maybe use of 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.
