The use of a grinder for cutting various materials, cutting and grinding wood. Is it possible to install a saw blade on a grinder Disc for cutting wood with an angle grinder

An angle grinder, a power tool familiar in working with metal, is also effectively used for processing other materials. Many people put a wood disc on the grinder without thinking about safety.

Is it possible to cut a tree with such a disc and what types auxiliary tool there are Bulgarians, let's figure it out.

There are special wood cutting discs designed for this job, but this is rather an exception. In addition, such a disk is not suitable for every angle grinder.
Let's consider several options.

Saw blades, blade and chain hybrid for chainsaws

These cutting discs can be used to cut boards up to 40 mm thick, with extreme care. Rules, non-observance of which lead to injuries:

The saw blade has metal base and a chainsaw chain fixed around the perimeter

1. It is strictly forbidden to remove the protective cover if the diameter of the disc exceeds the dimensions of the casing - your angle grinder cannot be used.
2. corner Grinder should run at the speed indicated on the disk. Otherwise, the chain may jump off and its components may fly apart.
3. Safety goggles and thick gloves are required. It also does not hurt to wear thick canvas clothes.

IMPORTANT! Use normal discs for circular saw, on an angle grinder is strictly prohibited.

The same applies to diamond cutting discs for concrete. For cutting work wooden products they are useless and dangerous. Firstly, the work efficiency is extremely low, especially considering the cost of the disk. Secondly, you can simply burn the workpiece.

And finally - such a disc can jam in the cut at any moment, and you will get hit by the grinder's body. Here is an example of a disc for a grinder, with which you can saw a tree with extreme care.

The design of the circle provides protection against jamming with the help of side teeth that expand the width of the cut. The disk has a diameter of 115 mm, and its dimensions allow you to work without removing the protective cover.

The wood disc fits completely under the protective cover

Some homegrown "masters" fit standard circular saw blades under, the work is done with the protective cover removed. Most often, such experiments end tragically. The unfortunate master receives severe injuries, and a fatal outcome is also possible.

At the same time, the construction markets are full of offers of saws for a grinder for wood. Sellers will assure you that in the hands of a professional, the use of such a tool is completely safe. This statement is true as long as these very hands are safe and sound.

Wood is a specific heterogeneous material that requires special wheels to work with. Discs for grinders for metal are categorically not suitable for cutting wood! Otherwise, the disk may be destroyed during operation.

The saw blade for wood for a grinder is the same as for a circular saw, but of a smaller diameter. In most cases, discs with a diameter of 115 mm and 125 mm are used, which can be bought in our online store.

Attention! Working with a saw blade is extremely dangerous and requires skill with an angle grinder and great care. When sawing, it is possible for the blade to jam in the wood, which will lead to the tool being pulled out of your hands and serious injury. It is categorically impossible to cut wood with a grinder "on weight". The tool must be securely fixed to the table.

Choosing a saw blade for a wood grinder

When choosing a saw blade for wood, pay attention to the shape of its teeth, which can be alternately beveled, straight and trapezoidal. In our online store you can buy wood circles for a grinder with variable beveled teeth with a diameter of 115 and 125 mm. They are suitable not only for sawing wood, but also for cutting aluminum and laminate.

Another factor to pay attention to is the number of teeth on the disc. The higher the tooth frequency, the cleaner the cut will be.

It's like a fairy tale about a unicorn, everyone has heard about it, but no one has seen it with their own eyes. The public of construction forums and authors of similar articles on the Internet is divided into two camps. The former say that in their life they sawed more than one cubic meter of wood with a grinder, the latter give strong arguments in favor of the fact that after such work you can miss your fingers or limbs, or even worse. Is there a disc for a wood grinder and if so, what does it look like and is it safe to work with it?

The author of this article kindly asks you not to consider this material as a guide to action. corner Sander is not intended for working with wood, even those manufacturers that produce discs and cutters for wood write on their official websites that it is extremely unsafe to cut wood with a grinder. But we all know that people rarely think about their health in the first place.

Cutting with an abrasive disc

Yes, it’s possible to cut a tree with a metal disc, to be honest, I myself, working at a construction site, have done it more than once. What can be said? Well, firstly, the speed of work with this method is low. Secondly, the smell of burnt wood even on outdoors within a radius of 10 meters you are provided. And thirdly, the thickness of the sawn board should not exceed four centimeters. This is not to say that the abrasive disc is not a wood disc for a grinder, its main purpose is to cut metal. As for the pros, in my opinion it is: the absence of sawdust, and a smooth, even cut.

Circular saw blade and its improved counterpart

The vast Internet is full of video materials on how to turn a circular disc or a diamond disc for concrete into a disc for working with wood. You can argue for a long time about whether it is worth doing or not? Even without considering himself helluva lot smart person, I would not conduct such experiments. And that's why:

• a circular saw blade is not designed for high speeds, yes, it is carbide, but no less fragile. A single chipped tooth can pose a great danger to a person.
• the edges of the toothed disc are not smooth, crashing into a tree, the grinder will vibrate and crash into the branches of the workpiece. this operation may cause the operator to lose control of the tool.
• increased chance of a kickback

There is an adapted disc for a wood grinder on sale, the manufacturers claim that due to the shape of the tooth and special expanders that are on the cutting part of the disc, all of the above concerns about tool jamming disappear. One of the manufacturers is the company Rotarex, in its assortment you can find both grinding and cutting discs for grinders. Below is an image of a circular disc and a grinder disc from Rotarex, which is universal. They can cut not only wood, but also aerated concrete.

Chain disk for wood grinder

At first glance, it may seem that this is a device for a horror movie, but judging by the reviews of the owners, this disc is safer than the analogues presented above. It is a solid circle, along the edges of which there is a chain from a chainsaw, everything is made of high-quality tool steel. The main purpose of such a disk: milling, modeling, stripping wood from bark and cutting cups in a log for log cabins. It is also possible to cut with such a disk, given that the width of the cut will be about eight millimeters, since the thickness chain disc is six millimeters. Speaking of diameters, there are 125 and 230 discs for sale. The service life of such a disc will be many times longer than that of others, since it can always be sharpened with a file. The price for them ranges from two to three thousand rubles, and even more will come out with delivery from another region.

Remember safety!

Whatever disc you work with and whatever material you cut, you should always remember that compliance with safety regulations can save you not only health, but also life. And before you get started, read the following points:

• not work in state alcohol intoxication;
• when working, use safety glasses and overalls;
• never remove the protective cover;
• it is forbidden to use a defective cutting disc or a disc with some, even minor, defects;
• when working with a grinder, hold it with both hands;
• the electrical cord must be at a distance from the rotating disk;
• do not put the tool down until the blade comes to a complete stop.

There are a lot of ways to cut a tree, one of them is to make a cutting disc out of paper. How effective this is, of course, is up to you to judge, but note that this is one of the safest options.

Angle grinder (angle grinder)

A wide range of power tools on the Russian market is designed to facilitate different types handmade. If in professional field purchase specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on an expensive tool that, after doing a certain job, may not be useful at all. The most popular power tool is the 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. Such a grinding attachment for a grinder is best used to remove a layer old paint. Suitable for lacquered finish which cannot be removed manually. It can be a wooden floor painted several times or a window sill. The design of abrasive discs consists of a disc and metal bristles made of elastic wire. Nozzles are available with different location steel bristles. Depending on achievement desired effect the villi can be placed along the entire perimeter of the disc parallel to the instrument or perpendicular to the segment - as in a conventional brush.

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

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

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

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 petals sandpaper, which overlap each other like fish scales (three-quarter overlap of the previous row). With this arrangement of the petals, the abrasion of the nozzle occurs much more slowly.

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

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

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

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

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

How to choose sanding attachments for an angle grinder

Circles should be selected according to the main parameters:

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

For each angle grinder model in without fail should be selected grinding head, only in this case will the safe performance of work be guaranteed and high-quality processing surfaces. Before you start working with a grinder (wood sanding), you need to make sure that the disk is properly fixed. Move corner car on the surface it is necessary to smoothly and not allow vibration of the tool.

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

The cost of circles for woodworking

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

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

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

Initially, you need to decide on the tool with which you plan to cut wood. It is known that discs are produced under standard sizes Bulgarians. The smallest diameter is 115 mm, but such a tool is used in extreme cases. The main advantage of such a grinder is its compactness, but it is extremely inconvenient to work with such a tool for a long time. The best option for woodworking - 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. When choosing a circle for a wood grinder, it is important to pay attention to the inner diameter of the shaft, which, according to the standard, is 22.2 mm.

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

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

Varieties of grinding wheels for wood

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

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

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

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

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

Varieties of cutting wheels for wood

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

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

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

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

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

What you need to know when working with angle grinders

Not only power tools, but also hand tools are a serious danger if safety rules are not followed. The nozzle on the grinder for cutting wood in this case is no exception. At the work of the angle grinder With woodworking discs, it is important to pay attention to the following points:

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

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

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