What disk to grind a tree with a grinder. Corner grinder or “Bulgarian”

How to cut a tree with a grinder correctly

A Bulgarian is a universal tool that is designed for grinding, polishing and sawing concrete, brick, stone, metal. Initially, the tool is not intended for wood processing. But after installing special nozzles and consumables, it is quite possible to use a wood grinder. The main thing is to choose the equipment correctly.

In the professional sphere, Ushm is rarely used to work with wooden blanks. Typically, masters have a whole arsenal of other tools. But in everyday life, if necessary, woodworking work, buying a set of equipment is impractical. Firstly, various jigsaws and saws can be needed only at once. Secondly, the equipment will cost an expensive. Therefore, it is much easier to purchase special nozzles for a grinder. After installing them, you can cut, cut, and grind a tree with any structure. If earlier with the help of standard equipment it was possible to make only a black cut of the workpieces, today there are nozzles and consumables of the commodity brand of combo, which allow you to perform quality processing. With their help, you can perform wood threads and sample, carry out peeling, cleaning and cutting work.

Characteristics of cutting nozzles

For processing a grinder and a disc saw, specially designed nozzles are needed, with which you can grind, polish and mill the surfaces. Choice for the master.

You can use such circles:

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

The choice of a suitable disk for a grinder

When selecting modern circles for a grinder, it is necessary to build on the properties and main functionality of each of the consumables. Many grinding circles have standard diameters. The most compact model of the tools includes a circle with a diameter of 115 mm, but the basic in the masters is the Bulgarian disk with a diameter of 125 mm. It is widely used among professionals and among craftsmen.

Natural wood is often a specific and heterogeneous structure, in this regard, it is necessary to use special circles. The disk for a grinder, which is designed to process a metal or concrete structure at all can not be used for wood. During its operation, the Ushm may be subject to breakdown and overheating.

When choosing grinding equipment, the size of the installation shaft should be taken into account, as a rule, the standard is 22.2 mm. Therefore, you should always pay attention to the labeling of the disk so that it fully corresponds to the size of the shaft. Nowadays, the dimensions of the circles of the standard saw disk are 125 x 22.2 mm.

Despite the fact that the Bulgarian has a maximum size for a circle with a diameter of 230 mm. The installation of such a overall cutting tool is better not to produce, especially for processing a tree. When using discs of more than 150 mm, the risk of injury increases significantly. Preferred values ​​- 115 x 22.2 and 125 x 22.2 mm. At the same time, through 125 mm of the circle, you can perform a fairly extensive list of tasks.

It is important to have a clear idea of ​​the specifics of the applied types of equipment. This allows the most correct method to select disks for an angular grinding machine in order to ensure safe and effective wood processing methods.

Wood grinding technique by grinder

Starting to process the tree with an angular grinding machine, you must keep two main points in my head:

  • Do not process the surface of the workpiece with the entire area of ​​the grinding disk, since there may be traces of the circle. Only the upper part of the nozzle is used.
  • During grinding, the grinder is led along the wood fibers: this will not remain traces. It is important to find such a support point so that the hands do not get tired.

The general process of grinding wooden surfaces is divided into several separate stages:

  • Preliminary preparation of the coating. All the remnants of the previous paint, varnish are removed with peeling grinding circles. It is also worth making sure that it is they who are polished from the floor or wall, nails, screws do not stick out. The protruding fasteners must be extracted, and if it is impossible. As deep as possible to load into the surface so that they do not affect the work of a grinder.

There are two more mandatory rules about grinding floors. Even if only a small area of ​​the floor is processed by a grinder, it is recommended to take out all the furniture from the room, and the doorways and Windows are hung with a thick film or oilcloth to protect against dust. Any cracks, gestures in the working surface are unacceptable. Only after gluing holes with a special putty on wood and drying can you begin grinding.

  • Primary grinding. It is carried out by large grain disks in the R20-R40 range. If there is no such circle at hand, you can cut and glue a piece. 2-3 passes by a grinder are performed throughout the working area. At this stage, it is especially important to control the pressure on the nozzle: weakly. The processing will turn out not good enough, too much. A large load on the Ushm engine.
  • Thin stripping. Replaceable petal nozzles of varying degrees of grainness are used. From P60 to P80. The master makes 1-2 full passes for the processed wooden workpiece.
  • Putting gaps. After grinding, it is necessary to eliminate all the gaps. First, they are on a nozzle with minimal grain, and after the processed areas are putty. It is worth highlighting two points here. In hard.To.Reach places, you will have to handle places manually. Plus, during the grinding, a lot of dust is formed, and we must not forget to remove it in a timely manner.

The final stages of grinding

The final polishing of the wooden surface is performed by grinding disks made of felt and soft fabric with p100 or p120 markings. A polishing pasta based on wax is previously applied to the tree, and then 1-2 passes along the processed surface area is made. After polishing it remains only to primed the surface. Due to priming, not only the remaining small roughnesses are smoothed out, but the life of the tree is also extended. As a primer for wood, oil paints or alkyd enamels are best suited.

The procedure is done manually with brushes in the following sequence:

  • It is good to wet the brush in the primer, apply to the workpiece, smear through the entire area.
  • Wait until the paint is completely absorbed, and the wood will dry out. At least 2 days.
  • Apply 2 more layers of primer, and the second can only be covered after the first dries.
  • After that, the primer will be completed. Can be applied to the tree of the upper lacquer.

Goluing of the galinded log and timber

Unlike hand.Made log logs, a looped log and a beam have a smooth surface, which causes certain difficulties when processing them with a grinder. One awkward movement. Both deep furrows and recesses that will remain there forever on the surface of the beam or a looped log.

Work by a grinder is not for beginners, it requires certain skills. Ushm. A high.Speed machine and with inept circulation can damage the surface. You can not press the tool to the processed area hard. Grinding must be done with smooth circular movements, holding a grinder at an angle of 45 degrees. Grinding and polishing the beam must be performed at low speeds. Large turns can lead to thermal destruction of the upper layer of wood.

How to grind a grinder

Do not forget that grinding is always associated with a lot of dust. Preparing for grinding, do not forget about yourself! Protective mask and respirator are the best helpers for grinding. You can find such an option where the mask is combined with a good respirator.

The respirator filter will be clogged very quickly, so you need to prepare several pieces for operational replacement at once. Only after careful preparatory work can you start grinding.

Grind the tree

Wood is a unique material. He manually grinds well, but with a grinder you can achieve very good results. Some snobs argue that the grinder cannot be grinded at all, but this is from ignorance and inability.

The main secret is the grinder is used at minimum speeds. If the grinder has a speed switch, then there will be no problems. At large speeds, sandpaper will be very quickly and very tightly clogged with wood. In this mode, it will not be enough for five minutes of work. Optimal speed of not more than 6,000 speeds.

Another secret is not to grind the whole area of ​​the circle. If you grind the entire surface, then circular traces will remain on the wood. So that there are no traces of sandpaper at all or they would be minimal, it is necessary to grind only the upper sector of the circle. Machine movements should be along the wood fibers.

This method can get excellent results when grinding the lining. The board becomes smooth and does not save the traces of the tool. No need to get carried away and change the sandpaper on the circle in time.

Similarly grinds the log house. Here it is desirable that the support plate is thin along the edge. With such a plate it will be easier to polish the narrow places of the adjustment of the logs. Otherwise, this work will have to be brought a chisel.

We work on concrete

If it was not possible to purchase a branded protective casing with a pipe for a vacuum cleaner, then it can be done with your own hands. To do this, take the used bucket of putty or glue with a diameter of a little more than a circle of grinder. Cut the bottom part at the height of a slightly larger collected grinding part.

Cut the hole in the bottom for installation on the gearbox and a hole for plastic plumbing angular discharge. Now we connect the vacuum cleaner hose to the pipe and work calmly.

The grinding circle must be designed for stone processing. Concrete and concrete surfaces are preferable to grind the entire surface of the circle. This will save processing time, and align the surface plane well.

Grinding the concrete floor must constantly control the plane with the help of the construction line, because due to the different density of concrete, you can make recesses. To process the docking seams between concrete filling, it will be sufficient to achieve one combination by level.

It is good to polish the concrete floors and surfaces of the Matrix diamond grinding cup. If the grinder is 150 mm, then a cup of 125 mm.

Grinding metal surfaces

Metal is polished according to different requirements. Most often, the metal is polished for painting or for further polishing. The main tool is recognized as a supporting cup with interchangeable sandpaper. The selection of sandpaper depends on the degree of processing and on the state of the metal.

During grinding, it is necessary to work only part of the disk. There should not be unprocessed areas on the surface.

Heycafe H1 Coffee Grinder Overview

Processed surfaces of ordinary steel, it is advisable to cover with a primer. The moisture contained in the air can very quickly cover the metal, and cause the appearance of rust.

Nuances of work on wood on wood

Professionals rarely use a grinder precisely for working with a tree, for this there are special devices and tools-a ribbon grinder, electric saw, electric pill. But in everyday life, if there is a need to perform woodworking work, buying a whole set of expensive tools is impractical, then a grinder with a nozzle for grinding wood comes to the rescue.

Cut

The Bulgarian is not the most popular tool for sawing wood, since it is a material with a fibrous structure. With insufficient fixation and the slightest fluctuation and a change in the angle of cutting, the fibers are rising, relaxed, chips, defects and scraps of sawdust and chips are formed, form.

How to use Your Angle Grinder on Wood

The cutting nozzle is justified only if the maximum stable fixation of the Ushm on the cutting table is. Using a grinder, you can only make a rough, not accurate cut, since it is impossible to organize all the conditions for accurate work. To fix the material, tool and see the place of cutting hard.

Grinding and polishing

Bulgarian is great for grinding. The work is carried out according to the following algorithm:

  • Preparatory work. Gross grinding is originally carried out using a roller nozzle. It has the appearance of a bowl with a twisted wire located around the entire perimeter (outwardly similar to a brush with metal bristles). At this stage, the old layers of paint and varnishes are removed from the board.
  • Preliminary (rough) grinding. The remains of the coating, bulging fibers and other defects are removed from the surface of the material. Work is carried out using grinding circles for wood grinder. At this stage, the preparation of the material for painting is carried out.
  • Final (thin) grinding. Used for wood that will not be painted. For work, a nozzle for grinding wood with an abrasive minimal grain. Zero is used for work.
  • Polishing. The engine is made at low speeds, fabric circles are used as an abrasive.

In order to carry out all the processes as conveniently and efficiently as possible, it is necessary to choose the right nozzle from the entire variety of their modifications.

Is it possible to cut a tree with a grinder? Secrets of specialists, how to do it right

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

Corner type grinding machine. Universal tool. The grinder is suitable for a whole spectrum of work, replacing a number of metal tools, often performing work even better and more precisely. This can boast of all the processes produced by the metal disk. But how are things with wood and chipboard? Is it safe? I want to figure out today how to do it at my own peril and risk.

Advantages of using a grinder for working with wood

The tool has a powerful engine, which allows it to easily cope with all breeds used in domestic housing construction and production. As a rule, we are talking about working with a beam, board and woodworking blanks. Even the minimum power of 500-700 watts will be enough to process standard lumber. But here another question arises: “Is it possible to cut a tree as such or logs with a grinder?»This will depend on the size of the nozzle, but it is in solving such problems that a chain saw is more likely to suit. The Bulgarian, in addition to performance, justifies itself in terms of functionality. Modern compact models weigh a little, but at the same time have a wide set of systems for adjustment, safety and management of equipment. The operator can individually configure the device in the depths of the cut, the number of revolutions, use the soft start and other possibilities.

When is it better to cut trees?

Emergency trees can be cut at any time of the year.

If it is not emergency, then The best time of the year for its cutting is determined based on the purpose of wood.

If the wood is turned into chips and scattered through the garden, then it makes no difference when it is cut, but it is better to bring down a tree in winter to obtain a business forest or even firewood.

Time choice for sanitary deforestation depends on many factors, the main of which are the tree breed and the type of disease. Therefore, only an experienced forester will be able to more accurately set the time for deforestation.

Disadvantages of wood processing by grinder

The main argument against the use of an angle grinding machine in working with wood. Safety. There are certain ergonomic nuances associated with the uncomfortable direction of the cut, but specialists from such tactics of the saw often stop the risks of injuries. Why is it dangerous to cut a tree with a grinder? Compared to the same jigsaw or circular saw, the angle.Grinding machine does not have a stopper. A device that physically stops the cut when a critical point passes through. In other words, when the planting area or the center of the cutting disk approaches the surface of the workpiece, the likelihood of a hook and leaving the tool from the hands increases. This can happen completely unexpectedly, as well as the direction of the rejection of the grinder. The second nuance is associated with the nozzle itself. For example, it is strictly forbidden wheels with attacking segments, since they can collapse in the process. But today manufacturers also produce special equipment for servicing soft building materials.

With your own hands or order?

High-quality sawing chipboard is difficult to manually produce due to the large size of the sheets. The dimensions of the standard slab are 2440 × 1200, and this is not the limit. However, if you work quite often with chipboard or MDF, it makes sense to get an expensive tool and work as a pleasure. If you need to cut only a few sheets, you can go in two ways:

Cut the slabs yourself using the available manual tool;

Order a chipboard cut in a specialized workshop.

What to choose, solve only you, and we will consider each of these options.

What disk for a grinder to cut a tree?

As already noted, a special equipment for angle grinders is presented on the construction equipment market, which are planned to process wood blanks. Usually these are adaptive discs with expanders in the cutting area and a special form of teeth. This design focuses on lowering the probability of wedge. Over, for wood, you can find both cut.Off and grinding circles. Another option for an acceptable nozzle for such purposes is chain equipment. But in working with her, it is necessary to take into account a wide capture of drank, about 8-10 mm. A chain disk with a grinder can be sawing a tree with a maximum depth of 125-230 mm. These are standard formats for an angle grinding machine, but the workflow will differ in a low level of vibrations and the lack of risk of leaving the tool from the hands.

How to choose a saw?

Wood hacksaw is presented on the market in different versions. How the products may differ:

A saw-cut with a change in one of these parameters can radically change its characteristics. Also, sitting comfortably in the hand of one master, it will not work at all at all. These factors must be taken into account when choosing a tool for different purposes.

The size of the teeth

This parameter affects the quality and speed of work. For the convenience of determining the size and number of teeth, the TPI designation indicates the number of teeth in one inch was introduced. This parameter can be seen in the description of a manual saw on wood, often the value is applied to the canvas.

  • Kryuzovka wood with a large tooth gives a rough saw at a high speed of work. It will come in handy for cleaning the territory from branches, sawing boards for firewood and other events where you can do with rough ends of products and trunks. For such tools, choose the size of the tooth TPI 3 6.
  • For products that must be sawed carefully and evenly, a hacksaw with a small tooth with TPI 7 9 is suitable. This is used for sawing fiberboard, chipboard, laminate, in repair work. The performance of such a tool is much lower than that of a large.Toothed.

The carpentry hacksaw is chosen, first of all, by the size of the tooth. So, for a regular tree, small and large, and for “delicate” materials such as fiberboard, you need a shallow saw. In stores, you can now find such designations: “for wood”, “for drywall”, and t.D. Their main difference is the size of the teeth, optimal for cutting each of the materials indicated on the label.

Loofing technology of boards

In everyday life, the most often has to polish boards. Elements of furniture, wall and flooring, etc.D. Regardless of which type of device is used, the technology is always approximately the same.

Training

Before you fabricate the tree, you need to prepare for work. Do the following:

  • Prepare sandpaper with different granularity. Mandatory options. Grain 40, 80, 120 and 180. Fine work will require another 150 and 240.
  • Clean wood from dirt and garbage. If necessary, wash and dry. Working on a wet tree is not worth it, even if a wet type of grinding is chosen. This increases the risk of damaging the surface of the tree and its structure.
  • Process with an abrasive with grain 120 (and if the defects are not too noticeable. 150). The purpose of this stage is to remove adhering dirt and glue, as well as old coatings, including paintwork.
  • Grinded with sandpaper with grain 180 or 240. This stage prepares wood for applying a finishing coating.

Primary grinding

First you need to skip the tree in the framework of primary grinding before moving on to a thinner work. This is done like this:

  • Use sandpaper with large grain. Best. 40 or 80. If you use a smaller abrasive, then at this stage it will be very quickly worn out.
  • Clean the surface of wood dust.
  • They process the same grain again.

Thin grinding

At the next stage, thin polishing of the tree is carried out:

  • Use an abrasive material with a grain of at least 120. At the same time, it should be borne in mind that the sandpaper will wear very quickly.
  • Provide the Rapid movement of sandpaper. If you are polished manually, then at this stage it is difficult. To achieve the desired result, the abrasive must move really quickly.

Often this stage is the last. After thin grinding, the tree is already suitable in order to cover it with paintwork. But if you need a better result, then it makes sense to continue.

Putty

Stage of putty is not mandatory. It is carried out if, after thin grinding on the wood, visible defects remain. Do this:

  • Take the most fine.Grained of existing sandpaper (180 or 240).
  • They work manually, even if the rest of the stages were carried out using a grinder.
  • The appearance of dust is periodically vacuumed or swept away with a brush.

This stage is required in the manufacture of furniture or dishes. But before painting, they can neglect.

Finished grinding

This stage is carried out before staining wood. Its basic principles are as follows:

  • Seek to remove all visible defects.
  • They select the sandpaper of any granularity. Depending on how smooth or rough the coating should be.
  • Can work both grinds and manually.

The result of the finish grinding should be a surface completely suitable for coating or varnish. And also some processes may differ. It all depends on what you need to polish and why.

After all, you can grind boards for a fence, children’s toys, a house from a profiled timber or log house. And accordingly, each process should be approached wisely.

Grinding a tree with a grinder of the nozzle: the purpose of grinding circles or disks, grinding with cup grinders of 125 mm diameters

Bulgarian belongs to universal equipment in demand in the construction market. For corner grinding and polishing wood on the axis of the tool, replaced discs are fixed. Grinding and polishing circles are available in many varieties and are divided by the type of abrasive surface.

A grinder or an angle grinding machine is a tool that is often used in construction and during repair work. If the house needs a small repair, buying powerful and expensive construction equipment does not make sense. But such a machine will be useful and relatively inexpensive. The versatility of a modern tool is its main advantage: with the help of Ushm they saw and cut, grind and level surfaces. The principle of operation of the grinder is simple: operations are performed by rotating nozzles.

Disks are divided into three types. Sharpening, cutting or grinding (peeling). Operations are different in terms of purpose and complexity, sometimes one machine has to process materials that are different in hardness, as a rule, these are stone and steel joints, as well as a tree. Updated and processed wooden parts, Windows, floors and furniture are subjected to grinding.

The nozzle on a grinder for grinding wood is a replacement circle similar to a similar circular saw. The peeling cutter for primary grinding is made of durable metal, has cloves and is selected in diameter for each Ushm. The size of the teeth is determined by the thickness of the wood layer. The shape of the tooth matters. Variables are suitable for all wood species, and trapezoidal is used only for soft varieties. The material can be processed with disks with straight cloves.

Saw wood before processing with other, sawing cutters. They are monolithic, made of high.Strength sheet steel. Some varieties are performed with spraying on the teeth.

How to grind a grinder

Do not forget that grinding is always associated with a lot of dust. Preparing for grinding, do not forget about yourself! Protective mask and respirator are the best helpers for grinding. You can find such an option where the mask is combined with a good respirator.

The respirator filter will be clogged very quickly, so you need to prepare several pieces for operational replacement at once. Only after careful preparatory work can you start grinding.

Processed surfaces of ordinary steel, it is advisable to cover with a primer. The moisture contained in the air can very quickly cover the metal, and cause the appearance of rust.

Than and how Grind wood

When conducting different types of repair, at the time of production of furniture or wooden things, wood rock is often grinded. There are many ways, the use of which allows you to polish wood. They have their advantages and shortcomings, some predict the introduction of a hand tool.

You can grind woody rock:

  • When using Ushm, there is an option to bring the condition of the tree to the desired state. The grinder has an abrasive material represented by a circle;
  • The ordinary drill is also used if you set the target to bring the surface of the tree to a suitable state;
  • Planning grinding machine can be the main design if you set the target to polish wood;
  • Ribbon grinding machines are used to polish wood using abrasive material;
  • Grinding using a hand tool is also performed.

Contrary to the fact that the natural material under consideration has a sufficiently higher hardness of the structure, many grinding methods are used, we will talk about some in details.

What are circles for cutting wood

Wood processing using a grinder is a safe process, unlike cutting. The process is very traumatic, the tool is not intended for cutting wood. Soft woods are treated with nozzle on a grinder with extreme caution, t.To. The tool can jam and tear out. The process of cutting at high speeds involves a high temperature effect on the disk material, as a result of which it can simply fly into small pieces.

Not paying attention to the fact that the Bulgarian is not suitable for cutting wood products, manufacturers offer various cutting discs for use. It is recommended to use a grinder as a stationary station when sawing wood.

Circular saws

Nozzles in the form of a circular saw are dangerous when using Ushm. The diameter of the circle must be selected based on the parameters, the size of the tool in order to be able to use a protective casing.

There are more expensive modifications of circular nozzles, they implement protection against jamming. The design has diluted teeth in different directions, smaller, the price of such a device is different, but you should not save on health.

Chain saws

A safer design has a chain type of nozzle. A cutting disk in which the chain from the chainsaw excludes the instrument junction and reduces injury hazard during operation. The design has a system that allows the main element that is mounted in the Ushm, and the chain may remain in a motionless state.

Chain discs are distributed in many different modifications, with which it is possible to perform summer cottages or use to harvest small firewood. The chain design disk can be used instead of the peeling, to cut the cups in the log or remove the bark layer.

Small dental saws

Increased safety in wood is achieved by the use of discs with a small number of teeth. Small disks usually have 3 teeth, with a diameter of more than 180 mm. 4 teeth. The presented type of cutting disk is used when cutting both along and across the wood fibers. The saw circle makes it possible to cut grooves, make spikes of various shapes.

It should be understood that when working, a grinder must adhere to the technical regulations. No need to install a larger diameter, bypassing the protective casing, the smaller drives can be used without losing the cutting properties.

Tungsten carbide disks

Carbide of tungsten carbides are made relatively recently, they are popular in the work of the Bulgarian. The universal tool is not equipped with teeth, instead of cutting elements, there are cuts in the disk. The work of the tool is the safest when cutting wood, excludes jamming when the nails or thick rods of wood. Appearance is like a diamond.Cutting disk of concrete, the purpose is indicated on the packaging or instructions.

The price of such a disk is high, but has an excuse. It is worth overpaying for a modified tool than to go bankrupt on the sad consequences of using a conventional file disk.

The danger of work with wood with wood

The only operations with wood that can be performed by an angular grinding machine (Ushm) without fear is grinding and peeling, and then using special nozzles. It will turn out to cut wood, of course, but it is very dangerous. The Internet is full of shocking photographs that indicate what the use of corner grinders leads to a detachment of wood tools.

The main arguments that can be brought against the use of Ushm for sawing, the following.

  • The design of this device is not designed for sawing wood.
  • Since the wood has a viscous and soft structure, the saw disk can jam in it. As a result, the grinder often pulls out of the hands, and she flies in an unpredictable direction (in the leg, hand, in the stomach, etc.D.), causing a person deep wounds or amputation of fingers. Even cases of death are attested.
  • When cutting wood, it occurs very quickly Heating of a saw disk, Why does he begin to lose strength. With the slightest distortion or excessive pressing, it can fly up. Since the spindle of the Ushm spindle is large, the fragments of the instrument fly apart at the speed of shrapnel and deeply enter the skin of a person. The user is lucky if the fragments fly not in the head or eyes.
  • Despite all the danger of using saw discs with teeth, some Ushm users ignore this fact and continue to install circular discs with large teeth or improved with carbide attacks. If a solid knot or the rest of the nail comes in when cutting wood, then the tooth or attacence is broken off, clings to the next tooth of the saw and throws out at the speed of the bullet. The consequences are only worth guessing.
  • Ignoring all warnings, users of the Bulgarians install a larger diameter circuit on the device than a protective casing. This is the most dangerous use of Ushm.

If you have to cut the tree constantly, it is better to purchase a special machine for these purposes, or Use an electrician. In extreme cases, the grinder can be used as a drive and make a circular from it, fixing the device hard on the bed.

Drill for grinding wood

For grinding a wooden house, you can use a regular drill. With this tool, you can quite easily and efficiently perform a small volume of grinding work. However, for large areas, the drill is not recommended to use. Grinding circles are also provided for the drill, in the center of which there is a pin for installation in the cartridge.

There are several types of nozzles for grinding drill:

  • Flat, made in the form of a circle on which grinding paper is glued. Nozzles are tough with Velcro or flexible rubber.Based.
  • Petal, consisting of abrasive petals, like nozzles on a grinder. When working with them you need to be careful. With inaccurate circulation, the petal nozzles can leave transverse lines on wood, which will occur through the varnish coating.
  • Drum nozzles are in the shape of a cylinder. The sandpaper is attached to the nozzle using a bolt. The drum is mainly used for grinding the ends of wooden blanks.

What to pay attention to when choosing a saw wood disk?

The key features on which you should FOCUS on when choosing a saw disk for a grinder are as follows:

  • The outer diameter of the equipment.The size of the circle largely depends on the power of the USM and the type of work on the work. The most suitable for wood are 2.5 cm discs. Larger diameter increases the performance of work, but requires professionalism and increased measures to comply with safety precautions.
