Disc for a grinder on wood: how to choose the right grinding and cutting wheel? Grinding attachment for grinder - how to grind wood with angle grinder Circular saw for wood for angle grinder

When working with wooden surfaces, the question arises whether the disc is suitable for angle grinders when working with wood. Today, the grinder is used when performing various operations, because it was made a universal tool.

With the help of such a device you can grind, polish, cut, saw and perform many other functions. She copes well with such material as wood, but before work you need to study some recommendations.

In this article we will talk about the disks for angle grinders, their types and attachments used when working with wood. There are many of these accessories for angle grinders and they all differ in purpose and characteristics.

Initially, you need to decide on the tool with which you plan to cut wood. It is known that discs are produced for standard sizes of angle grinders. The smallest diameter is 115 mm, but such a tool is used in extreme cases.

The main advantage of such a grinder is its compactness, but it is extremely inconvenient to work with such a tool for a long time. The best option for woodworking is a grinder with a 125 mm disc. It is this size of the circle for wood that is the safest, and therefore it has become widespread.

To work with angle grinders on wood, a special disk is required. It is strictly contraindicated to cut wood with abrasive or diamond circles. This will not help to cope with the task, but rather lead to the destruction or overheating of the tool.

It is forbidden to work as an angle grinder with installed disks that are intended for circulars. Because it poses a threat to human health and life.

When choosing a circle for a wood grinder, it is important to pay attention to the inner diameter of the shaft, which, according to the standard, is 22.2 mm.

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

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

Not only power tools, but also hand tools are a serious danger if safety rules are not followed. The nozzle on the grinder for cutting wood in this case is no exception.

the work of the angle grinder

Choose the right circle for the tool: according to the diameter of the outer and landing, and also depending on the type of wood.
Select the appropriate operating mode for the tool.
Do not use wheels that show obvious signs of damage.
Use personal protective equipment.

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

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

Each of these parts must be used for its intended purpose.

A saw blade for wood for a grinder consists of a metal circle with a chain attached to the edge. The design of special sawing tools is similar to those used for chainsaws. But saw blades are made of tungsten carbide.

When a disk for a grinder on a tree hits a solid obstacle in the wood - knots, resin, metal, its base rotates without breaking the chain. With chain nozzles, it is quite easy to clean the logs from knots and bark, to give them the necessary initial shape.

The thickness of the circle should be within 2 mm.
The depth of the cuts made can be within 20 mm.
Cutouts can be empty or filled with copper.

With the help of a saw blade for wood for an angle grinder, you can solve quite a large number of various tasks associated with construction, repair work, furniture production and landscaping of the backyard territory.

Saw blades for wood for grinders, visually practically do not differ from circles for a circular saw. But they are made of a completely different metal. Until recently, these products were rare, now there are quite a lot of high-quality tungsten carbide wood wheels on the market.

Important: in no case, do not even try to set the circle from the circular to the grinder. Theoretically, this can be done through an adapter, but circular discs designed for low speeds and in the grinder, in the vast majority of cases, they warp or simply scatter.

Rapide saw blades are made from high quality tool steel and are highly wear resistant. The carbide teeth of this blade are equipped with tungsten carbide tips and are precision ground.

Rapide 180mm saw blades for wood have 36 or 60 alternately set teeth, which, after long-term use of the blade, can be sharpened using special equipment.

This design allows you to successfully cut chipboard, MDF, laminated panels, hard and soft woods, getting a very clean and even cut. The Rapide 180mm saw blade has special temperature slots that serve to cool the blade and prevent it from overheating.

The inner diameter of such a circle - the seat - is 22.2 mm, which corresponds to the seat of an angle grinder (grinder). The outer diameter of the circle is 180mm and the use of a circle of this size is provided for by an angle grinder with an exclusively corresponding diameter - 180mm.

The use of this disc on any other power tools not specified by the manufacturer, or on angle grinders of a different diameter, is extremely dangerous and may result in serious injury.

One of the important advantages of Rapide saw blades is their ability to be used for various kinds cut - both for cross, and for longitudinal. The manufacturer recommends a permissible number of revolutions up to 80 meters per second.

The 180mm wood cutting disc for a grinder is quite popular among professional craftsmen for various carpentry work, sawing branches, logs and cutting firewood. This circle is often used in the manufacture of furniture, the manufacture of any structures or buildings from wooden beams.

Characteristics of the saw blade for wood 180 mm:

Producing country	Germany
Purpose	Saw
Material handling	MDF, Wood, Hardwood, Soft wood, chipboard
outer diameter	180.0 (mm)
Inner diameter	22.23 (mm)
Number of teeth	60 / 36
Amount in a package	1 PC.)

Chain saw blades for wood: application advantages

AT this case the saw circle is performed using a chain from a chainsaw. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency.

A chain drive on a tree for a grinder is also considered the safest. Using this attachment greatly reduces the chance of injury if the tool jams.

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

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

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

Various manufacturers also produce cutting wheels for wood specifically for angle grinders, for example, the Bosch cutting wheel. Their design is significantly different from the design of discs for circular saws.

bevelled;
straight;
in the form of a trapezoid.

The first version of the shape of the teeth is considered universal. It is suitable for all types of wood with small amounts of work. When sawing wood from soft varieties, it is quite possible to use discs for a grinder on wood with a straight tooth. Trapezoidal teeth are capable of processing quite solid products from wood: chipboard, fiberboard, OSB boards.

In addition, cut-off wheels vary in diameter. Minimum size- 115x22 mm. The most commonly used circles with a diameter of 125 mm, they are universal and suitable for a wide range of jobs.

Maximum possible size- 230 mm. But the latter option is undesirable to use when working with wood, as the likelihood of injury increases. Depending on the size chosen, the depth of cut in the wood will also be different.

saw blade

Universal or beveled wood saw blades for grinders are best used if you plan to work rarely in extreme cases, and any type of wood can be used as processed materials.
Wood discs with straight teeth are recommended if the technological process involves working with coniferous and softwoods.
The trapezoidal shape of the tooth is suitable for cutting medium-density chipboard. Most often, such a tooth is universal and suitable for sawing hardwoods.

A cutting disc for wood for an angle grinder 125 mm is classified not only by diameter and, accordingly, the depth of cut, but also by shape, frequency and number of teeth.

If you plan to use a wood saw blade for a 125 mm grinder from time to time, and you don’t know what kind of wood, you will need to cut it. Then the best option would be a circle with variable beveled teeth.

For cutting conifers, as well as for any other soft wood, products with straight teeth can be used.

A wider range of uses for a trapezoidal tooth. A wood saw blade for a grinder 125x22.2 mm with trapezoidal teeth, capable of cutting a medium-density chipboard. It also handles bilaminated particle boards, USB boards and medium density fibreboards with ease.

finishing

cord brushes;
end circles;
petal nozzles;
emery circles;
cutting nozzles.

Rough processing of wood is carried out with the help of special cord brushes. End discs are designed to level the edges of parts, which is often required when miter sawing workpieces. They make a great file replacement. The widest range of grinding attachments is for flap wheels.

Depending on the size of the abrasive grain, the surface of the wood can be cleaned with varying degrees of polishing. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved.

The system of trapezoidal petals, which are stacked with a three-quarter overlap on top of each other, wears rather slowly. If the relief surface of a wooden product is complex, then petal discs with a radial arrangement of abrasive strips are used.

Using sandpaper or sandpaper on a special nozzle allows you to grind quite large areas wooden surfaces. The ability to quickly change the sanding cover makes these tips versatile. When removing old paint and varnish coatings, peeling nozzles are often used.

As a rule, this is a wire brush attached to a metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for fixing the bristles on the perimeter of the disc.

When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, they must be cleaned to healthy wood.

Grinding disk for wood for a grinder: characteristics

With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out peeling work of varying degrees of complexity. 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 wood.

Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give wood unusual view, artificially age it.

However, with the help of a grinder with a peeling wire nozzle, only small volumes of wood can be processed. Thus, for brushing in industrial scale this item is not recommended.

Grinding is one of the most popular processes for which angle grinders are used. With the help of such a tool and a set of nozzles, it is possible to carry out rough and gentle processing of metal, stone and wooden surfaces.

As a rule, grinding precedes polishing of workpieces. The nozzles that are used in this case may consist of sandpaper or felt material.

The petal disk for the grinder was widely used. This tool consists of a circle (base), along the edges of which sandpaper petals are fixed. They may have different grain sizes. This indicator is selected depending on the nature of the work.

The use of a petal wheel allows for roughing workpieces from different materials. It can also be used for fine sanding. For finishing, fine-grained petals are used.

Today you can find another variety grinding discs to Bulgarian. Some abrasive products are fixed to the base with a special Velcro. To use such a circle, it is necessary to screw it onto the tool spindle.

Polishing is the softest wood treatment. For polishing work, which relate to the finishing stage of turning a particular material, special felt discs are used.

And also in the tool market you can find circles, the working part of which consists of thick fabric. Nozzles for polishing grinders are very popular when working with wood, as their use allows you to bring the surface of the material to the smoothest possible state.

If you decipher the abbreviation angle grinder, then it is clear that it is the finishing that is the main purpose of the grinder.

cord brushes

They are mainly used for primary (rough) grinding of wood, when it is required to smooth out the irregularities of the sample.

End disks

The names speak for themselves. Such nozzles process the final parts of wooden blanks (cuts). Especially effective if you have to deal with angular (oblique) cuts.

Petal nozzles

The most used grinding devices for the grinder.

Nozzle for grinder for brushing wood

Many craftsmen believe that metal brushes are used to clean rust and oxides of only steel products. In refutation of this fact, brass wire products are popular in wood processing. Relatively not high price, increased resource during operation, make the brush a direct competitor of abrasive nozzles.

The main purpose is to remove the paintwork from the surface of the material. It should be understood that the top layer of paint can be removed by exposure to temperature, the brush is used when working in hard-to-reach places.

It is also possible to brush wood with a grinder with a brush. The process implies artificial aging surfaces in the manufacture of unique interior products. The surface is processed with soft particles of wood, irregularities and temporary rings stand out against the general background.

Rules for working with the tool

Any tool can be a serious hazard if the instructions for use are not followed. specific situation. Bulgarian for cutting wood in this sense is no exception.

Correct circle size.
Installing a wood disc for a grinder.
Select the appropriate operating mode for the machine.
Refusal to use damaged circles.
Use of personal protective equipment.
The nozzle size should be installed without problems under the protective cover of the machine.

If this does not work, do not remove the protection. When working on wood with an angle grinder, it is necessary to use only special circles on wood for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or a damaged tool.

In order to avoid the destruction of the disk on wood for the grinder, the speed of the grinder must correspond to that indicated on the surface of the circle. Before starting work, it is worth checking the wood disk for defects and damage.

If they are present, then it becomes dangerous to use. When working with the tool, eye and hand protection must be used. It would be best to use tight overalls.

Brush cord. These tools are ideal for rough wood sanding. It is assumed the possibility of successful leveling of wood, with the addition optimal shape product.
End discs allow easy turning of workpieces. In most cases, such work is required for bevel cuts. Work end disk resembles the interaction of the workpiece with the saw.
Flap sanders are the most commonly used consumables. The characteristic of the tool determines the possibility of processing various workpieces, including natural wood.
Felt circle - allows you to achieve minimal roughness, processed products. The basis is pressed wool, fine-haired, semi-coarse-haired and coarse-haired. Felt working tool allows not only to carry out high-quality processing of wood, but also to give a perfectly smooth surface, comparable to a mirror.
A wheel for a grinder designed for grinding is often compared with a disc of the same name. It is important to note that the Velcro circle is a versatile tool with a wide range of applications.
Various woodworking tools certain tasks, but the grinding wheel sometimes surprises with its versatility and high level of efficiency.
The chain disc for wood is one of the most productive, but rough ways of processing natural material.

When choosing equipment, it is desirable to take into account not only the diameter, but also each accompanying informative designation. The inscriptions will allow you to determine the purpose of the tool and follow the recommendations during operation. Marking discs, circles and nozzles for grinders is a guarantee of a successful result.

A modern grinder is a convenient and effective tool. For high-quality work, special nozzles and discs are required to effectively process wood, metal and any other material of interest.

Safety rules at work

The use of angle grinders for wood processing requires a serious approach. Wrong work with a grinder can lead to injury, so before using it, experts advise you to pay attention to some rules for operating the device.

For example, before replacing one nozzle with another, you need to disconnect the angle grinder from the network. How to change the disk on the grinder? To answer this question, it is necessary to determine the type of circle. Some products are installed without removing the main nozzle. However, in most cases, it is required to unscrew the flange holding the element.

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

Treatment wood material with 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(angle grinder)

Wide selection of power tools Russian market designed to facilitate various types handmade. 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 issued with different arrangement of a steel bristle. 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 disk with a large abrasive coating, designed to perform rough grinding and removal of bumps 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 the molding 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.

While doing grinding work grinder 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 work surface is equipped with 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.

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.

For use 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);
landing diameter (setting a circle of a larger size to a smaller one is possible using 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 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".

A grinding nozzle must be selected for each angle grinder model, only in this case will the safe performance of work and high-quality surface treatment be guaranteed. 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:

Name of cities	Price of nozzles for wood, rubles per unit
Name of cities		Abrasive discs for soft grinding	Grinding (cleaning) circles	end	cord brushes
Moscow	from 70 to 900	from 35 to 14900	from 86 to 270	from 33 to 430	from 36 to 5400

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.

Modern angle grinders, better known as grinders, are used for various technological processes during construction and renovation. When choosing a disc for a wood grinder, you need to consider important features not only tools, but also processed objects. As a rule, the device is used for cutting metal. However, a large number of different disks allows you to use it to solve other problems.

First you need to decide on the tool (grinder - the correct name is a chain angle grinder), which is planned to cut wood. It is known that discs are manufactured according to standard sizes Bulgarians. The smallest diameter is 115 mm, but this tool is rarely used. The wide range of power tools on the market is designed to facilitate various types of manual labor. If specialized equipment is simply necessary when working in the professional field, then in everyday life it is not always rational to spend money on expensive hand tools.

To operate the machine with wood, a special drive is needed.. Absolutely contraindicated for cutting abrasive and diamond, carbide wheels. This will not help to cope with the task, but rather lead to the destruction or overheating of the device.

When choosing woodworking universal accessories, you should know that there are not only cutting discs, but also grinding wheels. To clean the tree, use the petal circle for the circular. Working surface such a device consists of several layers of sandpaper, which has a different degree of roughness. The lower the roughness, the softer the sanding. Flap wheels allow you to perform polishing, which depends on the degree of detail.

Grinding wheels and a cutter for a grinder must be of high quality, which affects not only the quality of the work performed, but also the safety of the master. Processing wet wood is prohibited, as the result of such manipulations can be unpredictable.

For roughing operations, which are often used as initial processing, special cleaning agents are used. They are necessary in order to remove a layer of paint from a painted surface.

For processing with a grinder and a circular saw, specially designed nozzles are needed, with which you can grind, polish and mill surfaces. The choice is up to the master.

You can use the following circles:

An abrasive wheel for wood, which is used to work with various surfaces. Depending on the thickness of the circle, it can be cut and polished.
The diamond wheel is designed to work with stone, concrete and other building materials. Such circles are divided into segmented and continuous. The first type, due to better performance and better cooling, provides improved performance. These discs can be used for minor metal cutting.
Regular circle. It should be noted that it is not recommended to use it for sawing wood products without experience. If possible, it is better to use another tool.

If you need to remove a layer of paint from a wooden surface, you must install the nozzle on the grinder. There are many for sale various options. They all differ in form, design and the specifics of the work that can be done with this tool.

The next cutter, due to the fact that the spikes on it are installed on a plane, allows you to level wooden surfaces - for example, if two boards on the floor in the place of the final construction are on different heights. This defect is easily eliminated, and the boards are then in the same plane.

There are circles of twisted wire or in the form of a disk with wire windings clamped in the central part. In addition to this, the circle is often used to change the wood, it gives it a worn look. If such an effect is applied on wide surfaces in a professional environment, it is better to use special hand-held machines with wide parts.

For grinding surfaces, there are special attachments consisting of a metal base on which an abrasive grinding ring is fixed. The circle is screwed onto the grinder shaft and tightened with a special key. Often it is equipped with an adapter for mounting in a drill holder or drilling machine.

To choose the right disc, first of all, you need to decide what material to work with.

Can be applied:

Thin blades (1-1.6 mm) are best for cutting thin sheet metal such as car body. When working with thicker corners, they can speed up the cut, but the risk of damage to the disc is greatly increased. In this case, it is safer to use thicker discs.
Rigid - most often used for active processing (cleaning) of welds after welding and gluing metal surfaces before welding. With their help, remove (cut out) braces and protrusions on the metal. They are also used in cases where the metal surface must be cleaned of rust or old paint.
Elastic - mainly used as an alternative to metal brushes. They perfectly clean even a curved metal surface from outdated paint and other similar coatings.
Coarse - used for grinding metal and wood. Even the smallest welds can be smoothed out with large discs (with the largest grit), but are mainly used for finer operations. They remove the faded top layer of wood surfaces, polish wooden beam, rust and outdated metal paint.
Abrasive - for working concrete, diamond blades are somewhat smaller, but they also have a shorter service life. Their use is justified only when it is necessary to perform a small one-time work.
Diamond blades are used for cutting various products made of concrete and stone (paving slabs, steps, curbs, facing stones), as well as bricks of all types.

For working with reinforced concrete and stone materials, turbo diamond blades (both conventional and wave) are best suited. When choosing, keep in mind that a turbo will provide a cleaner cut than a diamond wheel.

If the device has outside diameter only 125 mm, and the grinder is designed for 115 mm, it cannot be installed for the following reasons:

First, the discrepancy between the revolutions of the tool itself and the circle is dangerous for the user.
Secondly, when it heats up and expands, the disc can get stuck, resulting in a jerk.

The number of teeth matters. How less number, the faster the work will be, but the quality of the cut will be less, and vice versa, a larger number increases the cutting time, but the ends of the resulting parts will be smooth.

With a large number of small teeth, the device will work with low efficiency. Large teeth allow you to work faster. The cost of a disk depends on outer dimension, number of teeth, manufacturer. The most expensive model is with a circular saw.

For many reasons, it is better to buy circles from well-known companies. The concept of "quality disc" includes not only the degree of rupture of the disc and its abrasive properties, but also safety.

When choosing a new wheel, it is worth making sure that it is designed for the speed of the grinder. Permissible speed is indicated.

You need to follow the rule: the larger the rasp disc, the slower the speed. In addition, manufacturers protect the user as much as possible by releasing discs with a large (sometimes double) strength. But if the disk is used more than necessary, all these measures lose their meaning.

work with a protective cover;
protect the face and head;
check lumber for nails and screws;
hold the device firmly by hand;
use an additional handle (many hold the device with one hand);
do not allow the tool to heat up, avoiding the risk of smoke.

In addition, if you do not plan to work with a grinder on a large scale, you do not need to buy a lot of discs “in reserve” - since the humidity contained in the air begins to affect the bakelite. The bond strength is markedly reduced. It is better to get the right wood discs for angle grinders (grinders) immediately before work.

The modern grinder is often used to perform various works in the process of repair, construction. Such a tool can be called universal. The grinder easily cuts almost any object, grinds, sharpens, polishes and peels. To do the work with the help of a grinder, it is qualitatively necessary to select the right discs, taking into account the type of tool.

Discs for grinders on wood

Angle grinder (grinder) performs a wide range of different operations with rotational movements of replaceable discs or nozzles. The most commonly used circles for metal, stone, wood. All of them are divided into three main groups:

Cut-off
Sharpening (cleaning)
Grinding (roughing)

Each group has its own types of discs, which are designed for a specific type of work, including wood.

Woodworking discs look like a regular circular wheel, you need to know how to work with them, because careless movements or inattention can lead to serious injuries. The protective cover on the disc serves as a good protection, so it is better not to remove it from the tool and, for your own safety, use a wheel with fine teeth. According to experts, it is best to work with wood nozzles without a strong feed and try to permanently fix the angle grinder using a special device for this.

The most common can be circles on wood - milling cutters, they look like metal circles with teeth, they are specially made for cutting wood. Circles can be different in size, depending on the thickness of the timber, the diameter of the cutter is selected.

For sawing wood, only saw blades and right choice gives a wide range of possibilities. If you know how to use the tool, you can even make cutting at an angle.

Disc production

There are two types of saw blades for a grinder on wood - monolithic and with carbide soldering at the ends of the teeth. If there are such solderings on the saw blade, then they do not wear out so quickly, they do not require wiring, they cut better, but they need to be sharpened only on special machines.

For the production of saw blades, only carbide sheet steel. It guarantees the product high resistance to mechanical damage and temperature fluctuations. In the production process of the saw blade, great attention is paid to the weld, it connects the body of the blade with the teeth, so its quality is always under control.

The speed and frequency of cutting is affected by the number of teeth on the wheel, the greater the frequency of the teeth, the better the cutting of wood will be, but at the same time the speed of work decreases. When there are fewer teeth on the cutter, the speed increases, but the cleanliness of the cut deteriorates.

Influence of disc teeth

The end result of working with wood depends not only on the frequency of the teeth, but also on their shape. Universal saw blades can be called milling cutters with variable teeth, they work well with hard and soft woods. Products with trapezoidal teeth are only suitable for working with soft materials. For draft version fit circles with straight teeth.

When processing precious woods, you need to use thin saw blades, they are great for sawing or processing expensive wood. There are also "thin +" discs, where material is used with an additional chipper, it reduces blocking of the saw during its operation. This saw blade is suitable for longitudinal and cross cutting of wood and other materials. Similar materials from high precision cuts are also used in furniture and woodworking industries.

Features in working with saw blades

When working with a saw blade for wood, special care and skill must be exercised, it is best to put on special form and goggles and gloves. The complexity of working with wood lies in the fact that the tree is easier to cut, so it is necessary to observe control in the operation of the tool. Experts recommend using a tool of low power and speed when working with wood, the best option is 1,000 rpm.

Equally important is the quality of the grinder, as well as the cutter, the final result of the work and its safety will depend on this. It is best to give preference to a proven tool, to hear the opinion of experts in order to be sure of a positive result.

grinding wheels

To perform various works with the help of a grinder, grinding and polishing wheels, They may be:

spongy
Felt
With replaceable sandpaper
Cloth

The material is selected depending on the surface to be sanded. To process wood species, petal grinding wheels are used, they are made of sandpaper, which is fixed on a rigid frame. Sandpaper can be coarse and fine grit, the markings can be seen on the product itself.

If planned make wood smooth, then it is best to use a fine grit wheel, to remove a small layer of wood - medium grit. If you need to remove old paint, then you need to apply a coarse-grained circle.

According to their design, grinding wheels can be petal, movable and solid. Flap wheels give the smoothest surface to wood, therefore they are used as finishing circles.

Conclusion

When working with an angle grinder, you must always follow safety precautions. It is good when the tool is equipped with a persistent handle and a protective cover. Devices are considered safe, in the edge of which there is a chain from a chainsaw, it is specially installed there. In the event that one of the teeth is jammed, the disc rotates idle, and this reduces the risk of injury.

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 a log cabin is being built, 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 the technological operation. With certain skills, it is advisable to use these for finishing wood.

cutters

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

Purpose of cutters:

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

Application specifics:

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

wood sanding

If you decipher the abbreviation angle grinder, then it is clear that it is the finishing that is the main purpose of the grinder.

cord brushes

They are mainly used for primary (rough) grinding of wood, when it is required to smooth out the irregularities of the sample.

End disks

The names speak for themselves. Such nozzles process the final parts of wooden blanks (cuts). Especially effective if you have to deal with angular (oblique) cuts.

Petal nozzles

The most used grinding devices for the grinder.

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

grinding wheels

Most universal fixture to Bulgarian. It alone is enough for varying degrees of grinding. The nozzle itself is 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 quite a few products of this class, so it is easy to choose the best option 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).
