Cutting circle on wood for a grinder. Nozzles for a grinder for woodworking. Never put a saw blade on a grinder

An angle grinder, which is commonly called a grinder, is not intended for processing wooden products. Even with proper selection of working circles, such operations are unsafe for health. Manufacturers producing discs for wood grinder 125 refer to this aspect in operational conditions, but not all people pay attention to this warning.

Working discs for angle grinders

In modern industry for the grinder, several types of discs are provided:

  1. Abrasive wheels, which are divided into grinding and cutting wheels, are quite fragile if they are not used for their intended purpose. The range of operations for which they are designed is performed perfectly.
  2. Discs with diamond-coated that are used to process building materials and hard rocks. Subdivided into solid and segmented. Segmented discs are more suitable for grinders for metal.
  3. Working circles for circulars, which experts do not recommend using in the processing of wooden products. It is better to choose saw blades adapted for the grinder, which are also popularly called a milling cutter.
  4. Chain discs for grinders. Although outwardly they resemble shots from horror films, they cope with wood operations. the best way. They consist of a circle, along the edges of which a chain is applied like on a chainsaw. High-quality steel allows you to perform various operations with lumber, or rather, milling, modeling, stripping and cutting holes in logs.

When choosing wood discs for a grinder, you need to pay attention to the following points:

  • the diameter of the circles should not exceed the diameter for which the grinder is designed;
  • select the main details should be only those that are allowed for manipulation with the tree;
  • sometimes you have to remove the protective cover, which is unsafe.

Therefore, you should try to select only those working circles that are provided for these tools, taking into account the diameter of the grinder and the material. Experimenting with power tools at high speeds may result in injury.

The nuances of using each type of circle

Diamond wheels can be called universal because they are suitable for almost any material. For processing building stones and other hard rocks, this disc is ideal. But segmented diamond-coated wheels are not used for metal processing, and they will not cope with wood either. Lumber usually hides many surprises in the form of knots and structural heterogeneity.

Metal abrasive discs 125 may be used to cut through wood. But at the same time:

  • the thickness of the material should not exceed 4 cm (and it will have to be cut on both sides);
  • it is necessary to take a break regularly to check the circle;
  • change it at the slightest sign that the part has led;
  • change a worn disk in a timely manner.

And you should also be prepared for smoke and the smell of burnt wood. It can take more circles to process lumber than a steel plate.

The use of circular discs for an angle grinder 125 is dangerous to health and life. Although there are advisers on how to adapt a circle for a circular grinder, it is better to refuse such recommendations. If only because the speed of rotation on the angle grinder is higher, because of which there is a danger of breaking the circle and increased vibration of the power tool. Circular circles are very fragile, and during their use on the grinder, there is a possibility of injury from flying fragments.

In such cases, it is better to use a milling cutter for a circular saw. It is distinguished by the shape of the tooth and the presence of special expanders, which eliminates jamming, minimizes the appearance of a reverse impact and the occurrence of vibration.

For processing lumber, it is best to use chain discs for wood. The tool steel used for their manufacture is able to withstand loads and not shatter into fragments.

The service life of such a circle with a chain is several times longer than that of a cutter, in addition, it can always be sharpened. But the price of chain discs for a wood grinder 125 or 230 exceeds 2 thousand rubles.

Safety first!

Convenience in the use of angle grinders in operations with wooden material overshadows safety.

However, you can minimize the risk by observing some conditions:

  1. When working with a grinder, use safety glasses and overalls.
  2. The protective cover must not be removed.
  3. Do not use a defective wheel in work, as well as discs on which there are even the most minor defects.
  4. When working with a grinder, you should hold the tool with both hands.
  5. It is impossible to lay the grinder until the rotating part stops completely.
  6. The cord from the tool should be at a distance from the working circle.
  7. Refrain from planned actions with a grinder if you feel unwell and in a state of intoxication.
  8. Use wheels that are strictly suitable for the diameter of the tool and designed to work with the selected material.

These rules will help to avoid unnecessary injury when using the grinder in woodworking.

When choosing working discs for a grinder when buying, you should remember that it is better to spend a significant amount once, but to purchase a circle with a chain for a long time. It will help to perform many operations when working with lumber, as well as raw logs.

If the wheel is needed for a one-time use, you can opt for a milling cutter. Such a disc can also be used in working with aerated concrete and other materials. The cost of the cutter is lower than the chain cutter, but also exceeds the price of the abrasive device.

The most extreme case is the purchase of a cutting abrasive disc. But you should be prepared for strict observance of safety precautions: there is no need to swallow smoke and “enjoy” the aroma of burnt wood. In any case, such savings can cause irreparable harm to health, as well as lead to additional costs.

Bulgarian, being a universal tool for a home master or a professional, is used when performing many operations for cutting materials, grinding, peeling various surfaces etc. Sooner or later, every owner of this tool asks the question: is it possible to work on wood with a grinder, and what nozzles are needed for this?

The only woodworking operations that can be done with angled grinder(angle grinder) without fear is grinding and roughing, and then, using special nozzles. Cutting wood of course will work, but it is strictly forbidden! The Internet is full of shocking photos showing what the use of an angle grinder as a cutting tool for wood leads to.

The main arguments that can be made against the use of angle grinders for sawing are as follows.

  1. This machine is not designed for sawing wood.
  2. Since the wood has a viscous and soft structure, the saw blade can jam in it. As a result, the grinder is often pulls out of hand, and it flies in an unpredictable direction (in the leg, on the arms, in the stomach, etc.), causing deep wounds to a person or amputation of fingers. Even fatal cases have been documented.
  3. When cutting wood, it happens very quickly saw blade heating which causes it to lose strength. At the slightest distortion or excessive pressure, it can fly apart. Since the spindle speed of the angle grinder is high, the fragments of the tool scatter at the speed of shrapnel and enter deeply under the skin of a person. The user is lucky if the fragments do not fly into the head or eyes.
  4. Despite the risk of using saw blades with teeth, some angle grinder users ignore this fact and continue to install circular discs with large teeth or improved carbide tips. If, when cutting wood, a hard knot or the remainder of a nail gets into it, then the tooth or solder breaks off, clings to the next saw tooth and is thrown out at the speed of a bullet. The consequences can only be guessed at.
  5. Ignoring all the warnings, angle grinder users install a circular saw on the machine. larger diameter than a protective cover. This is the most dangerous option for using angle grinders.

Based on the foregoing, sawing a tree with an angle grinder is possible only at your own peril and risk, and then if this is a single or infrequent operation.

If you have to cut a tree constantly, then it is better to purchase a special machine for this purpose, or use a jigsaw. In extreme cases, the grinder can be used as a drive and make a circular out of it, fixing the apparatus rigidly on the frame.

What are the circles for cutting wood

Despite the danger of using angle grinders for cutting wood, tool manufacturers still produce saw blades for it.

Circular saws

The photo below shows "dangerous" saw blade for the grinder, although its diameter corresponds to the protective casing of the grinder with a maximum working tool of 180 mm. There are saws with soldering and a smaller diameter.

On the next photo you can see a less dangerous version of the circular saw. It provides protection against jamming, and it is implemented due to a small set of teeth in different directions.

Chain saws

A saw blade made using a chainsaw chain reduces the risk of injury when the tool jams. This nozzle is designed in such a way that the chain fixed on the inner disk (base) has non-fixed landing.

If the chain is jammed in the material being processed, the base continues to rotate, and the tool does not pull out of the hands.

These chain discs for the grinder have many modifications, and with their help you can cut branches in the garden, as well as use them for rough cutting of thin boards.

In addition to cutting, the chain disc can also be used how rough, for example, for removing the bark, as well as for cutting cups in log cabins and modeling.

Saws with few teeth

Also for the grinder, in order to increase the safety of working with wood, tool manufacturers produce cutting discs with a small number of teeth.

Small diameter discs can have 3 teeth, and large diameter discs can have 4, as shown in the following photo.

These discs for grinders remarkably cut wood both along the fibers and across. In addition, with the help saw blade you can cut grooves, make various cuts and spikes in the workpiece. But when working with an angle grinder, one rule should be followed: you need to install a cutting disc of such a diameter on the grinder, for the use of which it is designed by the manufacturer, that is, do not exceed its dimensions. Circles of smaller diameter can be set.

Tungsten Carbide Discs

Tungsten carbide discs for angle grinders have appeared on the market not so long ago and have made a kind of revolution in the field of woodworking.

The universal disc has no teeth. Instead of the latter, there are segments around the circumference of the nozzle. cutting disc its appearance is similar to a diamond wheel for cutting concrete. With the help of a tungsten carbide wheel for an angle grinder, you can very easily cut wood of any hardness and viscosity. In addition, he is not afraid of nails, screws and other metal inclusions that may be in the workpiece on his way.

This is the safest wood saw blade for an angle grinder.

Its price on the Internet is about 700 rubles. But when you consider the possible consequences of using circular saws, this is a low price for safety.

Wood sanding attachments

For wood processing, in addition to cutting wheels, there are specially designed for installation on angle grinder nozzles, which can be used for peeling, grinding, brushing and milling wooden surfaces.

Peeling nozzles

If you need to remove a layer of paint or other coating from a wooden surface, you can install a peeling nozzle on the grinder. Available for sale a large number of various nozzles for peeling works. They differ in shape, design, and in the types of work that can be performed with this tool.

The photo below shows disc nozzles. with spikes or chips with which you can easily remove upper layer wood, grind the end of the board, etc.

The next cutter, due to the fact that the spikes on it are located on a flat plane, allows leveling various wooden surfaces. For example, if 2 boards on the floor at the end connection are on different height. With this nozzle, the defect is easily eliminated, and the boards are joined in the same plane.

There are also peeling nozzles twisted wire. They can be made in the form of a metal cup with a wire inserted into it.

Or in the form of a disk with coils of wire clamped in its central part.

These brushes are used if you need to quickly peel old paint from a wooden surface or rust and paint from metal.

The next photo shows a brush with a smaller diameter wire, and it is used for finer roughing work on wood and metal.

In addition to stripping, this cork brush is often used for brushing wood, that is, giving it the effect of aging. If this effect is to be applied on large surfaces, in professional field, then for brushing it is better to use special manual machines with wide brushes.

Sanding and polishing tips

For grinding various surfaces, including wood, a special nozzle for angle grinders is commercially available, consisting of metal base, which is attached with Velcro emery grinding wheel . The nozzle is screwed onto the grinder shaft and tightened with an open-end wrench.

Often it is equipped with an adapter for fixing it in a drill or drilling machine chuck.

The grinding wheel is not used for polishing surfaces. Instead, they are installed on the nozzle felt discs that are fastened with Velcro.

It is also often used for sanding wooden surfaces. petal emery wheel. It is called from so because it consists of many petals fixed on its plane, made of sandpaper. The grit size of the latter can be selected based on the requirements for the treated surface. For rough sanding, emery with a large grain is suitable, and for finishing - vice versa.

The better to grind a tree - with a grinder or a grinder - depends on what you are going to prepare the wooden surface for. If under application regular paint, you can use a grinding wheel. If for varnishing, then the grinding wheel installed on the grinder cannot be used, since it will give small radial scratches on the surface of the wood, which will clearly appear after applying the varnish. In this case, longitudinal grinding is used for grinding. belt grinder(the emery belt moves longitudinally) or vibrating, where the same emery wheels are used.

Safety measures when working with a wood grinder

If you still decide to use the grinder as a tool for cutting wood, then you should remember some safety measures that cannot be ignored.

  1. Before installing the tool on the angle grinder, it must be disconnected from the power supply.
  2. Under no circumstances do not remove the protective cover from the angle grinder. This is the only barrier between the circular saw and your skin. In some cases, it will be able to protect your face from flying tool fragments.
  3. When working with a grinder on wood and not only the use of protective gloves is a must.
  4. Do not use large and powerful angle grinders for sawing wood. If the saw jams, you will not be able to hold the tool in your hands.
  5. Do not use saw blades with teeth large sizes, since the probability of them catching on the hard fibers of the wood increases many times and, accordingly, the probability of pulling the tool out of the hands increases.
  6. LBM must have speed controller to be reduced to a minimum. If there is no regulator in the device, then it is better not to risk your health. In extreme cases, the regulator can be made by hand, and installed in an extension cord socket.
  7. The grinder should be kept during sawing strictly at a right angle. From any slightest distortion, the circular saw can collapse.
  8. In no case should you fix the start button of the device, because in an emergency you will not be able to stop the tool and minimize injuries.

Angle grinder - 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.

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

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

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

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

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

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

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

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

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

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

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

    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 casing, 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 saves time.

    The following types of circles for wood can be distinguished:
  • saw on wood for a grinder;
  • cutting discs;
  • planes;
  • grinding.

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

A saw blade for wood for a grinder consists of a metal circle with a chain attached to the edge. Design of special saw tools similar to those used on chainsaws. But 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.

    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.

With the help of a saw blade for wood for an angle grinder, you can solve a fairly large number of different tasks related to construction, repair work, production of furniture and landscaping of the backyard territory.

Saw blades for wood for grinders, visually practically do not differ from circles for 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 are designed for low speeds and in the grinder, in the vast majority of cases, they warp or simply scatter.

saw blades trademark Rapide are made from high quality tool steel and are highly wear resistant. Carbide teeth this disk are equipped with tungsten carbide tips and have high-precision sharpening.

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

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

The inner diameter of such a circle - the seat - is 22.2 mm, which corresponds to seat 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 types of cuts - both for transverse and longitudinal. The manufacturer recommends a permissible number of revolutions up to 80 meters per second.

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

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.

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

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

    Usually they have side teeth that protect the nozzle from jamming. Differ cutting tools by number and shape of teeth:
  1. bevelled;
  2. straight;
  3. 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.

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

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

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

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

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

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

    This type of circles allows you to use the machine for its intended purpose. For finishing and polishing wooden surfaces, various types of nozzles can be used:
  1. cord brushes;
  2. end circles;
  3. petal nozzles;
  4. emery circles;
  5. 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 wood surface can be cleaned with varying degrees grinding. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved.

The system of trapezoidal petals, which are stacked with a three-quarter overlap on each other, wears rather slowly. If the 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 works 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.

Roughing discs on wood for grinders are also used to level the surface of the boards. Such circles are equipped with special spikes, which are placed on a flat plane. This feature is very useful, as it allows you to polish the boards from which the flooring is constructed.

On sale you can find peeling products consisting of twisted wire. They are usually called korshchekami. Such attachments for a grinder for woodworking are of two types, depending on the features of their structure. The first option provides for the presence of a base in the form of a glass to which the wire is attached. The second type is a disk with a wire fixed along the edge.

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

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

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

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

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

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

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

Use petal circle 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 type of grinding discs for grinders. 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 low 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.

    The main points that are necessary when working with disks for an angle grinder - angle grinder on wood:
  1. Correct circle size.
  2. Installing a wood disc for a grinder.
  3. Select the appropriate operating mode for the machine.
  4. Refusal to use damaged circles.
  5. Use of personal protective equipment.
  6. The nozzle size should be installed without problems under the protective cover of the machine.

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

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

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

    So, how to carry out the polishing and grinding process when processing wood? What tools do you need to be successful?
  • Brush cord. These tools are ideal for rough grinding tree. 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.
  • Petal sanding attachments- this is the most popular option used Supplies. The characteristic of the tool determines the possibility of processing various workpieces, including natural wood.
  • Felt circle - allows you to achieve minimal roughness, processed products. The basis is pressed wool, fine-haired, semi-coarse-haired and coarse-haired. Felt working tool allows not only to carry out quality processing wood, but also to give a perfectly smooth surface, comparable to a mirror.
  • A wheel for a grinder designed for grinding is often compared with a disc of the same name. It is important to note that the Velcro circle is 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 using angle grinders must be done with protective gloves. Sawing and cutting discs for wood are best used on medium (in terms of power) devices.

This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.

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

Any Bulgarian without fail must be equipped with a speed regulator, which must be moved to the minimum position. While working with cutting discs for an angle grinder it is very important to observe 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.

The Bulgarian is associated with an ordinary user with a tool for metal, concrete, brick. This is not the whole area where angle grinders are used. She can work with wood. There are special discs for the grinder. For sawing, milling, grinding wooden blanks, several types of cutting wheels are used. Each is designed to perform a narrow-profile task. Universal variant does not exist.

Saw blades are classified by diameter. This parameter is taken into account when selecting a nozzle for a specific model of an angle grinder. If the disc diameter is greater than the allowable one, then working with the tool is possible only after removing the protective cover, and this gross violation safety regulations. To avoid problems, cut-off wheels are available in several unified sizes:

  • 115 mm - sanding wood in hard to reach places
  • 125 mm - milling, grinding, debark
  • 150 mm - sawing boards
  • 180 mm - sawing thick boards
  • 230 mm - processing of massive workpieces. An angle grinder with a disk of this diameter is difficult to hold in your hands

Depending on the design, the wood grinder disc is used in several operations:

  • cutting
  • Cleanup
  • Milling
  • Grinding

Let's consider each in more detail, and also determine the nozzles for each type of work.

cutting

A wood grinder disc is rarely used directly in sawing. With it, you can process boards up to 40 mm thick, while observing safety regulations. There are two types of saw blades that can be used to cut a board:

  • Hybrid. It consists of a round metal base and a chain around it from a chainsaw. The nozzle is used when working with thin boards, with small cuts along the length.
  • Disc for circular or hand saw. This is a round saw element with teeth of different sizes located along its outer edge. The pitch and size of the tooth affect its characteristics. The larger it is, the more aggressive the sawing. The smaller, the neater the cut.

A standard circle for a circular or hand saw is cast from solid steel. It is designed for installation in a stationary machine with a hard seat. The angle grinder works at lower speeds, the disc constantly vibrates. This can lead to its destruction, as well as injury to the direct performer of the work and others. Therefore, this type of work is not always safe.


Cleanup

This is a rough job with wood, for which a wood grinder disc is suitable. There are two types of factory-made nozzles for this type of work.

  • The disk is a planer. Practical attachment for the primary processing of logs and ends of irregular boards. It is massive, durable, equipped with three knives. With its help, the tree is cleared of bark. For work, it is not necessary to install a protective cover, since the thick cutting wheel will not collapse.
  • Peeling. It consists of a metal base and a chain for a chainsaw, which trims its outer part. This structure allows you to perform a rough cleaning of wooden blanks from the bark, to even out cracks and chips. Peeling chain circle suitable for cutting wood.


Milling

Angular in progress grinder with wood attachments. Milling wheels in the workpiece cut grooves of different widths. The size depends on the thickness of the nozzle. A perfectly even cut, like on a machine, is over. But cutting out a simple landing socket or groove for a tongue will not be a particular problem.

There are solid and compound nozzles for milling. Compound circles make a wider cut.


Grinding

This is a finishing treatment of wood, designed to remove small bumps and roughness. There are several types of nozzles:

  • Cord brush. The working surface of the relief structure for deep, rough processing of wood. Cordbrush "bites" into the base, smoothing out bumps and chips.
  • End disk. Shaped like a bowl. Work surface - only a narrow strip with outside saw circle. This shape allows you to process end angle cuts, as well as hard-to-reach areas.
  • Petal nozzles for grinding. The most common type for finishing. It consists of a steel base glued with abrasive material. The depth and quality of sanding depends on the grain size of the sandpaper. The smaller it is, the smoother the surface will be at the output.

There are two versions. The first is a disk glued with pieces of sandpaper in the shape of a trapezoid. Each next petal is overlapped. With such a working surface it is effective to process wood. She is slowly fading away. The second is a flap disk, where the abrasive material is located radially. Suitable for processing workpieces in hard-to-reach places.

  • Velcro grinding wheel. It is designed for repeated use. Only the working surface of sandpaper, which is attached to the base with Velcro, changes. Stores sell sandpaper with different size grains. This allows you to use the nozzle, both for rough and fine grinding.






Rules for working with angle grinders

  • Works are carried out only in goggles and gloves. During coarse cleaning wood is better to cover the whole face.
  • It is forbidden to remove the protective cover from the angle grinder.
  • Work is done by holding the tool with both hands.
  • It is forbidden to use a saw blade with a larger diameter than indicated in the technical documentation for the tool.
  • While working with the tool, it is recommended to lean on both feet.

Firms - manufacturers

There are budget cutting wheels Hitachi, Makita, Luga. They grind faster, vibrate more than more expensive ones. The quality of the surface treatment differs from the result of more expensive analogues. Professionals choose Kronenflex saw blades from Klingspor or Bosch. They grind more slowly, practically do not vibrate. Less likely to be destroyed by improper use.
