I welcome you, my dear readers of the blog Andrei Noak. Many people ask the question on the forums whether it is possible to cut boards with a grinder? Therefore, I decided to fully understand this issue with you.

The angle grinder is a versatile tool. The Bulgarian is suitable for a whole range of jobs, replacing a whole range of tools for metal, often doing work even better and more accurately. This can boast all the processes produced by the disk on the metal. But how are things with the tree and chipboard? Is it safe? Today I want to figure out how to do it right at your own peril and risk.

They are discs that are produced by layering several different covers. To improve the abrasion characteristics of the treated surface, the initial layer is made of rubber, sometimes replaced with hard plastic. The layer of the second level of the nozzle allows to ensure the fit of the plane of the working part to the surface to be ground, it is made from foam rubber. The main working layer is a sheet of sandpaper.

The use of grinding plates allows you to work with high-quality painted surfaces. It is also possible to polish the rough surface in a rough way.

Petal-type discs are suitable for the same purposes, only in rough grinding it turns out faster. This type of disc is sandpaper attached to the working surface of the disc.

To remove the paint is best to take a special device with the functions of stripping. The steel cup, with fastened steel fibers from hard wire, perfectly wears, in addition to grinding wood.

Stripping tools

When you will use the nozzles already described, remember that the grinder circle may leave irregularities that are not visible after processing, but may appear after applying the paint. To avoid this effect, use a vibrating machine to level out the effect of roughness due to a circle.

The grinding operation is the simplest and safest operation that can be done by the grinder. In any case, follow the rules of TB.

Cutting wood, is it worth it?

Young people are always interested in whether it is possible to cut boards with a grinder? I will answer immediately, no! Although such an operation is permissible by many, it is worth taking it very carefully, because any violation of caution, disregard of the rules of TB, can lead to a disk rupture, followed by departure of particles in an unpredictable direction.

Why can't a newbie do this? Naturally, following the law of meanness, this direction can be directly your face, or other parts of the body. The speed developed by the torsion of the disc of a grinder can give a flying fragment a great acceleration.

Let's take a look at the most frequent and fraught mistakes of beginners:

• Using a grinder without a casing, taking off allows you to better control the direction of the cut, but completely removes all insurance against breaking the disc or flying chips;
• The use of non-standard disk for grinders, most often beginners try to use a heavy circular, which is also dangerous and can lead to irreversible consequences;
• Grip tool in the wrong place can provoke the sliding of the grinder from the hands.

Shocking photos on the Internet and equally scary eyewitness stories on forums confirm the danger of using grinders for sawing wood. These people, whose noncompliance with TB has led to amputations, serious injuries and even death.

The following information contains comprehensive tips to prevent accidents, like those inexperienced guys.

It is for the grinder there is a special disc on wood, designed for sawing wood at high speed. On sale such a circle is not as common.

Do not remove the protective cover! It is the only obstacle between your skin and the circle spinning at great speed.

Large grinders will not perform high-quality sawing. Because of the sawing of hard wood, they can break free of hands, since at the speed of the grinder, grasping a tooth of a circle behind tightly pressed wood fibers is unlikely.

Gloves at work - a mandatory requirement. Best of all get a fixation device. This will turn the grinder into a full-fledged machine, protecting you completely from tearing out, in the case of high-quality installation design.

Do not use cutting wheels with large teeth, with them the probability of the grinder clinging, especially for, becomes even lower. The possibility of pulling out grows at times.

With adjustable number of turns on the device, set the minimum value. Unfortunately, most Bulgarians simply do not have this feature.

You should put the tool at a right angle, you can cut the workpiece relative to the plane to be cut. Any bias can be dangerous. The inclinations of the apparatus are also highly discouraged.

If there is a button lock, do not use it. In a critical situation, you can not turn off the device, trying to minimize the damage.

Despite all the tips and rules, the process of sawing a tree with the help of a grinder can be so random that the observance of all these precautions cannot be guaranteed to protect the master. This is due to the fact that the Bulgarian is not the target tool for performing such tasks.

Therefore, if you have any alternative opportunity to refuse to use this tool in favor of a stationary machine - immediately make a decision to use it, even if its transportation takes a lot of time and effort. In any case, health, as well as your own life is more expensive.

The advice of many specialists is the categorical rejection of this tool for this purpose. If there is a large amount of work, then the choice should fall on the jigsaw, which will never be superfluous in the economy.

Milling with the help of the grinder

Another operation that has been successfully performed by many experienced craftsmen with the help of this tool is milling. Unlike a frezer, you will not be able to perform really high-quality processing. However, to make a groove, as well as cut the part of a small size - it will turn out quite tolerable.

Again, this operation is dangerous. I have already written recommendations for a general action with the help of this tool, so please follow them. The grinder needs a thick and high-quality milling cutter. Immediately dismiss the possibility of using self-made nozzles, give your choice to the old brand, insured from chips and faults.

Even with all the tips, the novice alone should not be taken for milling without the supervision of a more experienced master. As mentioned above, accidents constantly occur with the masters of their craft, given the instability of the tool.

For quick stripping of large areas used grinding nozzles for a drill. The benefits of this tool are hard to overestimate. Disk, brush, rubber conic, pan, kratsovki - all these brushes are made for quick cleaning and processing of metal, walls, natural stone and other hard surfaces.

The scope of this tool is very wide. For smoothing small irregularities of the stone, cleaning the walls from the layers of old lime and paint, use rigid metal brushes that will easily clean any area in a short time. Their cleaning surface consists of wire and has high wear resistance, while maintaining rigidity for a long time.

For polishing, processing and removing shallow rust from the surface of thin-walled metals, use kratsovki, wrist and cup nozzles on the drill. They are similar in design, and thanks to good balancing, these tips can work with fairly large areas. These nozzles are used for rough grinding of plastic and cleaning wood structures from paintwork materials.

Often, for the primary (coarse) area stripping use conical brushes. They have a thick and very hard metal pile, which increases their productivity, but leaves rough traces of processing on the surface. They are used for removing large layers of rust, grinding stone, removing slag, etc. Various versions of these brushes are used to work with grinders and grinders.

Disk brushes have a flat shape and are used as grinders nozzles, drills and grinding grinders. Disk brushes with woven steel pile are used for rough work, and brushes made of thinner steel wire for surface finishing.

Rubber nozzles on drills and grinders are used to grind various surfaces from residual defects and to impart a final form to the workpiece. For different materials, use different density rubber nozzles, which greatly increases the efficiency and speed of work.

STAYER company is engaged in the production of metal grinding nozzles for drills, grinders and grinding machines. On sale, on the pages of our online store, there are various types of metal brushes that differ in their level of rigidity, size and scope of application.

Wood has always been the most common material for the production of furniture, the arrangement of floors and the construction of buildings. It does not lose its position today, primarily due to its environmental friendliness. In the process of processing wood, it is often necessary to grind it, most often for this stage of work, special nozzles for grinders are used.

Description

The Bulgarian belongs to the category of universal tools and is equipped with various tools presented in a wide variety. For their manufacture, a rigid base is used, on which abrasive elements with different grain sizes are fixed.

Circles are selected in accordance with the intended materials and tasks. Fine-grained nozzle on the grinder for sanding wood is necessary to obtain a smooth surface at the final stage of work. Elements with a large grain are used for roughing boards and logs.

Varieties

The circles can have different diameters; for a standard tool, elements are suitable whose size is within 180 mm. Polishing can be done with felt, cloth, spongy elements or with several types of emery paper. In the process of processing, small abrasive compositions and pastes are also used, without which it is impossible to do if it is necessary to obtain a perfectly flat surface.

Velcro disc

Such a product is used not only for polishing wood, but also for grinding metal elements. Nozzle on the grinder for sanding wood is made in the form of a disk, which is applied a special adhesive paste. It is used together with sanding paper, the reverse side of which is also covered with an adhesive layer. So, the material is mounted on the base and remains in place throughout all phases of work. A circle may have a different density and thickness. Soft products are used for polishing; this is because if they are rigid, they can lead to the appearance of grooves on the surface with careless use. That is why finishing fine work should be performed with the help of elements having a soft base.

Plays no less a role than the grinder, the degree of grain directly affects the quality of the surface. Rough processing is first performed with a large grain, then the grain size gradually decreases. There are special products whose surface is similar to ordinary paper, they are necessary for the finest processing.

Petal circle

This grinding nozzle on the grinder resembles a disk equipped with velcro, but the cost of processing using such elements increases markedly due to the impossibility of reusable use.

The circle has a plate-shaped form, elements are fixed on its basis. Grains with different sizes are used, but coarse-grained products are most common, as the flap disc is mainly used for roughing metal and wooden surfaces.

It should be noted that in the process of work nozzles for grinders are often clogged, this is especially noticeable on the elements with fine grain. Because of this, they are not suitable for removing the paint layer. In order to prolong the period of disk operation, it is necessary to limit the rotation frequency when performing processing. Also, when working with a wooden surface, it is not necessary to exert excessive efforts; otherwise, furrows and holes may appear on the material.

Steel brushes

Grinding nozzle on the grinder of this type is presented in several variations. It is used for various bases and differs in a design, and also thickness of a wire. It is suitable for removing paint, welding scale and corrosion.

Rough cleaning is carried out using brushes with a flat shape and corrugated wire, the diameter of which is about 0.3 mm. Also twisted brushes are often used, they are resistant to abrasion and sufficient rigidity, due to the fact that the wire is twisted into small bunches. They are indispensable for processing large areas and require minimal effort.

Wire nozzles for brass grinders are suitable for fine work, they are made of thin wire with a diameter of not more than 0.2 mm and allow you to get a perfectly cleaned surface.

The most popular steel brushes bowl-shaped with twisted wire. Working with them requires considerable effort, but they easily remove layers of rust and paint.

Wall chaser

Nozzle on the grinder for chroming is characterized by the presence of a flat sole and a design with an increased width, making it possible to adjust the depth of the holes. It is complemented by a special pipe to remove dust, which is connected to a hose from a conventional vacuum cleaner.

Before the sale of such products engaged large firms, they were made from scrap materials at home. Today they are represented in all shops of related products, and their purchase will be cheaper than buying a separate wall chaser. The nozzle on the grinder should be supplemented by the first of which is fastened with a conventional nut. To fix the second, a special fastener is used with an additional ring, which is often included. If it is not available, the product can be machined independently on a lathe. Since a lot of dust appears in the process of shaving, it is necessary to use a household or construction vacuum cleaner, it is enough to connect the hose to the nozzle - and you can work with the tool.

Chainsaw Attachment

The Bulgarian is a convenient universal tool that can be made from an ordinary chainsaw with the help of a special nozzle. There are various types of similar products that are made for devices from different manufacturers. It should be noted that during their operation there is a high risk of disk breakage caused by the difference in speed. To reduce the likelihood of injury during work, it is necessary to use a protective cover and, if possible, reduce the speed of rotation of the chainsaw. Also should be taken into account the factor that the engine tool is not designed to hit the construction dust, because of what it can overheat and fail.

How to choose

To get a perfectly smooth surface, you must use different nozzles for grinders, which have different degrees of graininess. Accordingly, you need to purchase sets of products or pick up a few circles, suitable for coarse and fine cleaning. They can be found in any construction market and in a store selling products for construction and repair.

Korschtki are not the best option for wood, as they lead to the appearance of chips on the surface.

It is selected depending on the available tool. This item is of particular importance, since the use of unsuitable elements, can lead to breakage of the grinder. The cost of products varies depending on the manufacturer, size and type.

Before you buy circles with Velcro, you need to take into account some features. Since the operation of the tool is characterized by a large number of revolutions, the grinding head on the grinder becomes very hot and can ignite. The best option are discs with many holes that provide cooling products. You also need to monitor the state of the sandpaper and choose segments with a large thickness, since its surface is quickly erased, after which the disk itself is used.

The Bulgarian is a multifunctional tool, with the help of it one can not only cut or grind metal. The list of works is decent, respectively, for each type of work has its own nozzles. Let us examine what they are and in what works are applied.

Velcro polishing discs

Thanks to such discs, you can grind or polish wood, metal, stone and other types of surfaces. The base is a platform (as a rule with a diameter of 125 mm, although there are more, 150 and 180 mm) on which various disks are mounted with the help of special fasteners - stickies. For such sites there are sandpaper discs with which you can easily grind wood or metal. They look like this (note, for the grinder it is better to take without holes, the discs with holes go already for vibration grinders):

The graininess of sandpaper discs is different, starting with coarse (p40) and ending with the smallest (p180-220). They are sold in a set of 5 pieces, the approximate price of 60 rubles. A more detailed article about them.

In addition to sandpaper sheets, polishing discs can also be attached to the base, most often they are made of felt (polishing felt as it is also called). Also fasten with velcro. It is possible to polish metal or plastic, plexiglas, marble and other surfaces with such circles. The metal is polished using GOI paste, which is applied to the felt circle. Looks like this:

Also there are purely polishing nozzles of sheep wool, which are also attached to the velcro. A photo:

This is the finest polishing, to give a mirror shine. It is worth noting that polishing is best done grinder, which has an adjustment of speed. Such tips can also be found in magazines, just ask a wool circle with Velcro for grinders:

Petal circles

A great tool with which it is very convenient to sand wooden surfaces. The disk consists of layers of sandpaper, which are superimposed on each other around the entire circumference. If you need to grind a log house to make the tree smooth, then a petal circle will be very useful. Of course, you can use the sticky nozzles, but the flap disc will last much longer.

The size range is very extensive, ranging from 115 mm for a small grinder and ending with 230 mm for a large angle grinder. With one such circle, up to 10 square meters of wooden surface is processed. The cost of one circle with a diameter of 115 mm 40 rubles, 150 mm is already more expensive, within 60 rubles. They are described in more detail.

Korshchetki - nozzles of wire.

Peeling rust from metal is not an easy task, especially if it is done manually. Therefore, specially developed for the grinder korshcheti - wire brushes, disc and cup, with which you can clean the rust easily and without much physical cost. Take a look at this picture - tips for the grinder are two upper right - a cup and a disk.

In addition to rust, you can also peel off the old paint with iron (most often used in car services to prepare cars for painting). Some masters even try to work on wood, for example, when it is necessary to strip old paint from a window. I do not recommend doing this, after wire processing, the tree becomes “hairy” and chips stick out everywhere. What kind of subsequent painting can we talk about? Therefore, if you need to strip, for example, the old paint from the tree, use the nozzles of sandpaper.

Diamond flexible grinding wheels - the so-called "turtles"

Professional tips on the grinder exclusively for polishing stone, most often they are used for polishing marble and granite. That is, it is a natural stone. Of course, they can also be polished and porcelain. Most often used by engravers to process marble and granite monuments, they look like this:

The grain of "turtles" starts from 30 (the largest) and ends with disks 1500, 3000 and BUFF (for mirror polishing of granite). Such flexible polishing discs are most often used in memorial companies for processing monuments (when a figure is being cut out of the plate, and sections are polished to a mirror shine).

As you can see, the list of nozzles is pretty decent, so the home master will surely choose one that will help to do the housework quickly, efficiently and without much physical expense.
