We choose nozzles for a grinder for wood processing - types and characteristics. Wood cutting disc for grinder: choosing the right tool Diamond wood cutting wheel for grinder

Bulgarian or angle Sander allows you to process various materials, including wood. If it becomes necessary to cut metal, they resort to using an abrasive disc on a grinder. If you need to cut a brick or ceramic tiles, then diamond discs come to the rescue, due to their high strength and durability. What to do if you need to saw or grind wood? To do this, you will need to purchase a special disc for a wood grinder.

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 wheels. This will not help to cope with the task, but rather lead to the destruction or overheating of the tool. 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.

It's important to know! Older models of angle grinders may have a different shaft diameter, so this point is important to consider when buying the appropriate circle.

The optimal circle for woodworking has following options: 125x22.5 mm. Bulgarians for discs from 150 mm and above are not recommended for wood, as the risk of serious injury increases. It is better to use tools for cutting or grinding wood under 125 or 115 circle diameters.

Varieties of grinding wheels for wood

When choosing attachments for a grinder for woodworking, you should know that there are not only cutting discs but also grinding. To grind wood with an angle grinder, a petal nozzle is used. The working surface of such a consumable consists of several layers sandpaper, which has different degrees of roughness. The lower the roughness, the softer the sanding can be. Flap wheels allow you to carry out not only grinding, but also polishing work, which depends on the degree of granularity.

In addition to petal, there are also such types of nozzles that are very popular - these are sticky discs. They are known for their versatility, as they allow quick replacement using a special Velcro. The cost of such consumables is much lower than that of the first option, but at the same time they have a shorter service life.

Grinding and polishing discs for the grinder must be of high quality, which affects not only the quality doable work but also on the safety of the master. The quality of wood processing is influenced by such a factor as the degree of its dryness. Processing raw wood is prohibited, as the result of such manipulations can be unpredictable.

If it is required to carry out peeling work, which is often carried out as an initial processing, then special peeling nozzles are used. They are mainly used for those purposes to remove a layer of paint from a painted surface. Such nozzles are metal plates, inside of which there is a metal bristle made of wire.

It's important to know! It is not difficult to carry out grinding or polishing wood with a grinder, but it is important to observe safety precautions.

Varieties of cutting wheels for wood

If you need cutting discs for a grinder for wood, then you should initially pay attention to such parameters as the diameter of the circle, the depth of cut and the characteristics of the teeth. Depending on the wood material, a wood saw blade with the following teeth must be used:

1. 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.
2. Wood discs with straight teeth are recommended if technological process provides work with coniferous and soft breeds of wood.
3. 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.

Features in working with saw blades are due to the following factors:

• 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.(!)

It's important to know! When working with saw blades or cutting discs for wood grinders, you should be especially careful and careful. Without special need and experience, it is better not to carry out such work or replace them with other tools.

What you need to know when working with angle grinders

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. When working with angle grinders for woodworking discs, it is important to pay attention to the following points:

1. Choose the right circle for the tool: according to the diameter of the outer and landing, and also depending on the type of wood.
2. Select the appropriate operating mode for the tool.
3. Do not use wheels that show obvious signs of damage.
4. Resort to application individual funds protection.

It is not necessary to carry out work without the use of a protective cover, with the exception of carrying out manipulations on peeling, grinding and polishing wooden surfaces. It is especially dangerous to work with saw wheels. It is strictly forbidden to resort to installing discs from a circular saw or other tools on the angle grinder. For angle grinders, you can only use consumables that are directly intended for it.

In conclusion, it should be summed up and noted that grinder wheels for woodworking are no less popular than abrasive wheels. After all, the use of such consumables greatly facilitates the work of a person, and also significantly saves time.

Angle grinder (angle grinder)

A wide range of power tools on the Russian market is designed to facilitate different types self made. If in professional field purchase specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on an expensive tool that, after doing a certain job, may not be useful at all. The most popular power tool is the angular Grinder(UShM). The scope of its application is not limited to metal processing - grinding wood with a grinder is done using special nozzles.

For those who do not know "Is it possible to process wood with a grinder?" this article will be helpful. For grinding and polishing 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 intended. The most requested are:

• Roughing circles. Such a grinding attachment for a grinder is best used to remove a layer 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.

• Cordbrushes are a coarse abrasive coated disc designed for rough sanding and removing roughness on a 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. Its working surface is equipped with a large number of 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.

Sanded finish on different stages processing may remain a little rough or will be perfectly smooth 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. The universal nozzle for the grinder for grinding wood appeared on the market relatively recently and is distinguished by a special design and high functionality. Draft work is intended to be carried out by replaceable discs with the 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);
• type of segment (suitable for special nozzles for processing wooden 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 study wooden surface for the presence of fungus, cracks and irregularities. A video is provided to help beginners who want to know "How to properly grind a tree with a grinder".

For each angle grinder model in without fail the grinding attachment must be selected, 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. It is necessary to move the angle grinder on the surface smoothly and not to allow the tool to vibrate.

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.

If you are trying to understand whether it is possible to saw a tree with a grinder, then the answer to this question is unequivocal: it is possible. But many will not do this, because. too many injuries people get precisely from using the grinder as a saw for wood, which is correctly called an angle grinder.

First of all, this is due to the rather high speed of its rotation, for which most saw blades are simply not designed. But who pays attention to this when you need to do the work, and there seems to be a suitable tool at hand, and there is also a compensator ring for a saw blade for wood right size applied. Moreover, the protective cover is removed for the convenience of work, which is absolutely impossible to do.

But, we won’t talk about injuries, but we’ll talk about how and how you can process (including sawing) a tree with the help of an angle grinder, but first, about the difficulties of working with a grinder with wood.

Difficulties when working with a grinder

We mentioned the discrepancy between the speed of the grinder and the circular saw, but users who have an angle grinder with speed control can say that this factor has been taken into account, and any saw blade for wood is suitable for their tool.

Of course, by setting the number of revolutions of the output shaft of the grinder, corresponding to that indicated on the marking of the saw blade, they significantly reduce the risk of injury during operation, but do not completely eliminate it. This is primarily due to the material itself, or rather its structure and heterogeneity.

Even in different places of the same trunk, the tree has different hardness, not to mention the inclusions of viscous resin, the possible presence of metal that ended up in the thickness of the wood: from pellets and bullets that fell into the tree during a hunt, to a wire ingrown into it, with which branches were tied. Do not forget about the knots that are present in almost all types of wood.

When meeting with the listed obstacles, the saw blade brakes sharply and the angle grinder, by inertia, simply pulls out of the hands, and when passing through a hard section, it rushes forward with a vengeance.

When meeting with metal, there is a high probability of chipping of a hard-alloy tooth, which can be captured by the next one and thrown out at the speed of a bullet. Well, if in the area of ​​​​action of the protective casing.

A person who decides to cut a tree is in even greater danger, because at the same time the grinder must be put on its side, from which the usual and comfortable grip changes, which means that the grip weakens.

Discs for grinders designed for cutting wood

1. Chain discs and cutters based on them.

Structurally, they are designed so that even when biting a chain similar in structure to saw chains for chainsaws, the base can rotate, so the tool will not be pulled out of the hands. These discs are primarily intended for outdoor processing wood: sawing cups in log cabin logs, removing bark, modeling, but you can also saw with them, especially with a size 230 disc, which costs a lot, but compensates for its cost with safe work.

2. Saw blades for wood with a small number of teeth.

To enlarge an image, click on it.

Such discs indicate the maximum speed and should be selected based on the parameters of your tool. Such a large pitch between the teeth compensates for the high speed of the grinder and makes sawing much safer than working with standard saw blades, but metal in wood should also be wary. You can see their work in the video:

In addition to wood, they also cope with plastic and aerated concrete.

3. Tungsten carbide discs.

This is a novelty in the field of tools for angle grinders, which allows you to freely cut wood without fear of metal inclusions, operating at rotation speeds up to 12200 rpm. She is the only one who gives an absolutely positive answer to the question: is it possible to cut a tree with a grinder. You can see for yourself by watching a short video about the operation of this disk:

Needless to say, these discs cut more than just wood.

4. Other tool, more or less suitable for cutting or other wood processing with a grinder.

About all in order:

a) Rotarex manufactures discs for cutting wood. In terms of their performance, primarily safety, they are inferior to those listed above, but are clearly more suitable for sawing wood than circular discs;

b) cutters for wood intended for outdoor processing wood angle grinder, can also saw not thick wood;

c) disk-planer - a nozzle for an angle grinder.

d) a saw for creating wooden sculptures with a configuration of cutting elements remotely resembling links saw chain, not quite designed for sawing, but will cope with it to some extent.

Bulgarian for grinding wood

But this work, incl. on wood, just for this tool. Only a small photo selection of nozzles for angle grinders for grinding is evidence of this.

• for rough grinding.

• the most common type of nozzles for grinding angle grinders, the purity depends on the size of the abrasive grain on the petals.

• easiest way to change grinding wheels using a holder attachment with a sticky base, on which replaceable abrasive wheels with different grains or even polishing bristles are attached.

• polymer abrasive silicon carbide with nylon.

• sanding belt.

And instead of a conclusion. Can a grinder cut wood? Depending on what and depending on what. If you cut a thin dry branch, then there are practically no restrictions, and if you have to do more serious work, see above.

Dear readers, if you still have questions, ask them using the form below. We will be glad to communicate with you;)

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

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

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

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

Abrasive coated discs

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

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

The disadvantages include:

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

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

1. Solid. One-piece disc with a continuous diamond-coated edge. Designed for wet metal cutting.
2. Segmented, in which the cutting edge is divided into segments. Used for dry cutting.
3. Turbodisk with cutting edge in the form of a wave, in connection with which the contact area with the workpiece is reduced, which ensures the natural cooling of the circle. Can be used for both wet and dry cutting.

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

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

Wood discs for angle grinders

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

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

Wood sanding discs

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

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

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

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

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 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 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 wide selection 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. 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.

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

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.

Disks 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. 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 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, it is produced rough grinding, 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.

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, it may be necessary fine finish. 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 grinding wheels on wood at once. 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 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.

Useful 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. Choice desired grit 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. These tips provide maximum smoothness. working surface which is difficult to achieve with 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.

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. 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 angle grinder must be equipped with a speed controller, which must be moved to the minimum position. When working with cutoffs, 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.
