Chain disc for a grinder for cutting wood. Grinding attachment for a grinder - how to grind a tree with an angle grinder. The nuances of using each type of circle

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 a circular circle on the grinder. 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 the work on a 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.

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.

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

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

saw;
with diamond coating;
abrasive.

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

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

Note! The use of angle grinders requires compliance with certain rules. One of them claims that it is impossible to use circles of a larger diameter than indicated in the device's passport.

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

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

Types of wood discs for angle grinders: design options

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

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

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

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

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

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

Chain saw blades for wood: application advantages

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

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. The functionality of chain products allows them to be used as peeling tools. They do an excellent job of removing the bark.

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

Cutting disc for wood for a grinder: features

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

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

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

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

USB plates;
wood fiber boards.

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

Grinding disk for wood for a grinder: characteristics

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.

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

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

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

Grinding and polishing discs for wood on a grinder

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

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

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

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

Grinding wheels for grinders on wood: rough grinding

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

peeling;
corsets;
end circles.

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

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

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

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

The use of grinding attachments greatly simplifies the processing of wooden blanks. Such products allow you to restore old furniture by removing paint and varnish compositions from its surface.

Grinding discs for grinders: flap discs

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

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

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

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

Grinding wheel for grinders: soft processing and polishing

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

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

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

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

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

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

Nozzles for wood processing differ in high efficiency and quality. Sequential use of these disks allows you to achieve incredible results. The wood surface after their use can be compared with a mirror.

Safety rules when working with a wood grinder

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

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

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

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

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

Currently, an angle grinder, popularly known as a grinder, is deservedly considered one of the most versatile tools. It is in the arsenal of almost any good owner. With such an assistant, it becomes possible to quickly and effortlessly cut, grind, polish, peel or saw almost any material with your own hands.

The secret of such unheard-of popularity is the simplicity of the instrument. The instruction for the grinder provides for fastening a certain disk or nozzle to a rotating shaft.

After that, depending on the purpose of the disk, you can perform certain work. The scope of application can be varied, but in this article we will focus more on cutting and processing wood.

Tip: according to most experts, it can only be used for fragmentary work. Moreover, this must be done very carefully, the risk of injury is too high.

General characteristics and purpose of disks

The range of this product is simply huge, in each sector there are dozens of types of products. But all this mass can be divided into several main areas.

Disk types

Wheels or discs with an abrasive coating are designed for grinding and polishing various surfaces. Since the wood is not polished, a wood grinding disc for a grinder is used in this sector.
Diamond-coated wheels are more used in construction, they are segmented and solid. With their help, especially durable materials are cut, such as stone, concrete monolith and, in some cases, metal. For carpentry, such products are not used.

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, this product was a rarity, now there are quite a lot of high-quality wheels for wood made of tungsten carbide 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.

Regardless of the purpose, all circles have several standard diameters. The smallest wood disc for grinder 115 mm. But the most popular is a wood disc for a 125 mm grinder.

Wood is a specific material, so you should not take circles for it designed for cutting concrete or metal.. These materials require high strength and high speed, in a tree such a circle can simply get stuck, which will lead to its destruction or burn your grinder.
The shaft diameter in all modern angle grinders for wood is standard and is 22.2 mm. But, in the recent past, there were several gradations, so you should pay attention to the markings. For example, a wood saw blade for a 125x22.2 mm grinder can be installed through a nozzle on a thin shaft of an outdated machine, but if the shaft is thicker, your circle will be useless.

Important: the maximum diameter of a manual angle grinder is 230 mm. So, even if you manage to find a wood disc for a 230 mm grinder, then it is better to refuse to install and use it. The fact is that the larger the diameter, the higher the likelihood of injury, especially when working with wood.

cutting wheel

In view of the fact that this tool is characterized by high speed and cannot be rigidly fixed in the hands, for such circles, high-strength tungsten carbide is taken, and therefore the price for them is solid.

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.

What is a “grinder” at the present time, even a schoolboy knows, 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. Wood grinder disc - types, general characteristics and standard sizes, as well as safety measures for use and a review of prices for popular models - this is the topic of this editorial article site

Depending on the type of discs used, the “grinder” in skillful hands can be used at various stages of working with wooden blanks: from sawing to grinding

"Bulgarian" was not originally intended for sawing wood, especially for workpieces of considerable thickness and hardwood. This is due to the design features of 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 for professional use, it is most correct to use tools originally designed for sawing wood, which are circular and circular saws.”

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 regard, different types of similar products have different general characteristics, 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. A distinctive feature of the “less dangerous” type models is the presence of jamming protection provided by the set of teeth.

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

Ask a Question

“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 metal products (nails, self-tapping screws, etc.) that 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.

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:

Safety measures when working with a grinder on wood

When performing work on wood processing using an angle grinder, the safety measures are the same as in cases of using metal and other materials. However, due to the physical properties of wood, which have already been written about above (softness and viscosity), it is necessary to take them into account, and in this regard:
