Disc for grinder on wood: general characteristics and types. Cutting circle. Grinding and peeling works. Grinding discs for grinders in woodworking Homemade wood disc for grinders

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

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

• saw;
• With diamond-coated;
• abrasive.

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

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

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

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

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

Types of wood discs for angle grinders: design options

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

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

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

Saws with a small number of teeth. This kind of circles was invented specifically in order to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones - 4. This group also includes cutting discs for a grinder on wood 125 mm. 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. Distinctive feature such products - the absence of teeth. The edge of the disk consists of segments that are characterized by high strength.

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

Chain saw blades for wood: application advantages

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

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

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

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

Cutting disc for wood for a grinder: features

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

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 for specific situation nozzle. 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 universal option cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.

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

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

• USB plates;
• wood fiber boards.

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

Grinding disk for wood for a grinder: characteristics

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 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 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 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 wooden materials varying degrees density.

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

Grinding wheels for grinders on wood: rough grinding

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

• peeling;
• corsets;
• end circles.

Grinding wood with a grinder using a peeling product is most often used to remove a layer 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, it is possible to select the right tool corresponding to one or another variant of grinding.

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

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

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

Grinding discs for grinders: flap discs

After rough processing, 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 necessary action. To perform grinding, you can use a common nozzle - a petal circle.

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

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 at once grinding wheels on wood. This will enable you to quickly rough cleaning, 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 petal circle it is recommended to practice on wooden parts.

Grinding wheel for grinders: soft processing and polishing

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

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

Grinding disc for wood grinder of this type has one advantage - ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so using such discs is quite convenient. Sticky nozzles can be easily purchased on the construction market or ordered on the Internet. 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 speed angle grinder contributes to uniform polishing of wood.

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

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

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

Safety rules when working with a wood grinder

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

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

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

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

corner Sander - universal fixture, 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.

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 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.

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 are consumables. 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).

Angle grinder (angle grinder)

Wide selection of power tools Russian market designed to facilitate different types self made. If in professional field the purchase of specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on an expensive tool, which, after performing certain work, may not be useful at all. The most popular power tool is the angle grinder (angle grinder). The scope of its application is not limited to metal processing - grinding wood with a grinder is carried out using special nozzles.

For those who do not know "Is it possible to process wood with a grinder?" this article will be helpful. To perform grinding and polishing of wooden products or large surfaces of the array, you will need to purchase the appropriate nozzle - a circle. For grinders different sizes nozzles are selected, designed for a certain speed of rotation. Special discs designed for wood processing must be carefully selected. The disc must match the dimensions of the tool; a special nut is used to secure it.

When working with angle grinders, it is necessary to strictly observe safety precautions and use only factory wheels that are suitable for a particular model of power tool.

Wood processing grinder

Coarse wood grinding discs for angle grinders

There are several varieties of circles that differ in shape, material of manufacture and purpose. As a rule, the wood blank must first be subjected to a rough surface treatment, after which it is subjected to fine or final detailing of the coating with abrasive segments.

For such work, a special attachment for a grinder for grinding wood is designed. The most requested are:

• Roughing circles. This grinder attachment is best used to remove a layer of old paint. Suitable for lacquered finish which cannot be removed manually. It can be a wooden floor painted several times or a window sill. The design of abrasive discs consists of a disc and metal bristles made of elastic wire. Nozzles are available with different location steel bristles. Depending on achievement desired effect the villi can be placed along the entire perimeter of the disc parallel to the instrument or perpendicular to the segment - as in a conventional brush.

• Cord brushes are a disc with a coarse abrasive coating designed to perform rough grinding and removing irregularities wooden surface. With the help of this tool, the wood blank acquires its final shape. Productivity of works in comparison with the usual manual tool is much higher.

• End discs. Nozzles are used when you need to align the product from the end. Such processing requires oblique cuts and the edges of the workpiece. The execution technique is identical to the file, but the abrasive is more effective than hand tool. When working with a segment, it is important to have skills and then such a simple tool can completely replace moulder cutter in terms of edge processing.

With the help of a grinder for polishing wood, you can completely restore furniture covered with varnish and paint. After this stripping, the thickness wooden base practically does not decrease, but the newly painted furniture will look beautiful and impressive.

When performing grinding work with a grinder, the choice of tool is not so significant compared to the presence of well-dried wood and the absence of cracks on the surface.

Grinding wheels for gentle processing and their areas of application

To perform wood grinding with a grinder, nozzles of a universal design and with a special gentle coating are used. Such mechanical restoration intended for the production of certain works:

• The petal disc is used for grinding the array. The design of this segment corresponds to its name. His working surface equipped large quantity trapezoidal sandpaper petals that overlap each other like fish scales (three-quarter overlap of the previous row). With this arrangement of the petals, the abrasion of the nozzle occurs much more slowly.

This is the most common type of attachment for a grinder for wood grinding, which performs a soft surface treatment, and the tool itself is less traumatic. To achieve the desired degree of processing and High Quality the disc is selected according to the grain size. The size of the abrasive determines how quickly and efficiently the irregularities on the wooden surface will be removed.

The polished coating at different stages of processing may remain a little rough or be perfectly even without the slightest flaws and hooks. The final result can be achieved with a consistent transition from abrasive discs with a coarse-grained fraction to segments for finer processing. Therefore, you will need several discs per angle grinder for grinding wood, which will change in stages.

To use the petal nozzle, certain skills are required, which means that training before performing responsible work will be simply necessary.

• Wheels for soft grinding. Universal nozzle on the grinder for grinding wood appeared on the market relatively recently and is distinguished by a special design and high functionality. Rough work is intended to perform removable disks with desired grain size, which are attached to the sticky base of the nozzle. In this regard, the abrasive tool received the appropriate name - sticky disc.

The main advantage of a wheel grinder for wood grinding is the quick change of a worn-out removable disc: the whole procedure takes place without removing the main nozzle, which is fixed with a nut. First you need to purchase a sticky attachment for grinding on a grinder, so that later, without any difficulties, you can replace the worn abrasive segment.

How to choose sanding attachments for an angle grinder

Circles should be selected according to the main parameters:

• outer diameter (with large sizes, the processing process is accelerated and the service life is increased);
• bore diameter (circle setting bigger size to a smaller one is possible with the help of a special adapter);
• thickness (the greater the thickness, the longer the segment will last);
• grit (the fraction must correspond to the type of processing: a coarse abrasive for rough work, and a fine one for soft processing and creating a finish coating);
• segment type (suitable special nozzles for wood surfaces).

Reference! The diameter of the shaft in modern angle grinders for wood is 22.2 mm.

What you need to know when working with a grinder

Update floor covering(parquet), furniture or facade of the house, where there are wooden structures or individual elements, is performed using a grinder for grinding, which is equipped with different nozzles. Therefore, it is not surprising that angle grinders for wood polishing are in demand among professionals and in everyday life. But in order to choose the right tool for the job, you need to carefully examine the wooden surface for the presence of fungus, cracks and bumps. A video is provided to help beginners who want to know "How to properly grind a tree with a grinder".

For each model of angle grinder, it is mandatory to select grinding head, only in this case will the safe performance of work be guaranteed and high-quality processing surfaces. Before you start working with a grinder (wood sanding), you need to make sure that the disk is properly fixed. Move corner car on the surface it is necessary to smoothly and not allow vibration of the tool.

When working with an angle grinder for grinding wood, it is unacceptable to use discs of small thickness (high rotation speed and load lead to a break in the circle, which is fraught with injuries).

The cost of circles for woodworking

The price of a tool for polishing a wooden surface is not high, but depends on the material, diameter and thickness. The table shows average cost abrasive tool in major cities Russia:

Handmade requires application quality tool, and an angle grinder with nozzles greatly facilitates the work and speeds up the process of processing a wooden surface.

Many homely owners have home arsenal grinder - this is how the people call the corner grinder. And so, when it becomes necessary to work with a tree: cut boards, cut down branches on trees or prepare firewood; and there is no appropriate electric saw at hand: circular, jigsaw, chain, etc .; some savvy craftsmen say to themselves: “So what ?! After all, there is a Bulgarian! You can totally get by with it!" How right are such resourceful masters? .. This is exactly what our article is about.

Never put a saw blade on grinders!

This is not just the title of an article subtitle, it is a cry from the heart of all power tool sellers. Indeed, they very often come to them with the same request: “Give me a saw blade for a grinder so that the tree can be cut.” And they all unanimously answer in such cases: “They don’t cut wood with an angle grinder! And in general, by definition, it is impossible to put a saw blade on an angle grinder! Why is that? We contacted the developers with this question. cutting tool TM attack and they gave us a comprehensive answer on this topic.

Yes, an angle grinder (angle grinder) is a powerful tool, and it can easily cut both a simple board and a thick log, as long as the saw blade diameter is right. But cutting wood with a saw blade mounted on an angle grinder is, first of all, very traumatic, especially if the protective cover is removed from it. After all, the angle grinder has a very high rotation speed, which creates centrifugal force, which will significantly increase the load on the saw blade. In addition, a circular saw is structurally different from an abrasive wheel - it has teeth, and this circumstance leads to increased vibration, especially if you install saw blades for metal. As a result, such a load will significantly exceed the tensile strength of the circular saw blade, it can simply break during rotation. What this is fraught with, probably, it has already become clear to everyone. And in such a situation, nothing will save from injuries: neither the protective cover of the grinder, nor individual funds cutter protection.

To prove the danger of such disk “castling”, all kinds of tests were carried out. Yes, and in life there were many cases when the "savvy" owner was left without arms or legs. And in 2011 there was unique case, when a certain “economic” Volgograd citizen decided to cut branches from a tree at his dacha with the help of an angle grinder and installed a circular saw blade on it. As a result, he was delivered to the thoracic surgery department with a torn chest. Fortunately for the poor fellow, everything ended well.

Is it possible to install a circle from a grinder on a circular?

The question can be rephrased: can circular saw use as angle grinder? In principle, this is possible. If you install an abrasive or diamond disc, then there is no risk for the cutter in this case. However, the circular is very poorly adapted for such operation. Yes, when you need a straight cut, a saw will do the job. better grinders, but its protection from dust is much worse than that of the latter. Both the cutter itself and the tool are swallowed up with dust - then it will take a long time to blow it through.

In addition, the rotation speed circular saw significantly lower than what is required for effective work circles from angle grinders. For example, if you install a diamond abrasive disc on a circular saw and try to cut ceramic granite with it, then the engine can easily burn out. And the circles themselves will wear out faster. After all, sawy and abrasive discs designed for different angular speeds.

And once again we repeat: do not use saw blades on the grinder! Better buy an inexpensive circular saw!
