Belt grinder from a grinder. Polishing a car with an angle grinder Motor and polishing discs

A grinder or polisher is required to complete painting work. Tool shops and other outlets there are many models of such devices. However, in some cases it is advisable to create a polishing machine with your own hands. This article discusses various options such homemade devices and describes the process of their creation.

The simplest polishing machine

The easiest way to do it yourself is a polishing machine designed to work with grinding discs. To create this device, you will need the following main parts:

  • electric motor;
  • power unit;
  • battery.

The electric motor can be extracted from various electrical tools and appliances. So, for example, components of a computer power supply or a drive are suitable.

You can also use an electric motor from a fan, and a household battery is suitable for driving an electric motor.

In addition to the above components, you will need a board, it needs to be sanded sandpaper. Next, the battery and the electric motor are fixed with screws on the board and connected with wires. It is also necessary to install a switch in this electrical circuit, fixing it on the board. The wires should be fixed with a stapler to prevent loosening.

The working element of the considered design is represented by a circle. You can use branded products or you can make your own sandpaper sanding disc. To do this, you need to cut out two sectors from a fragment of the source material and fasten them together with their back sides, gluing them together.

To ensure the drive of the abrasive disc from the axis of the electric motor, two bushings are required. The diameter of these fixtures is determined based on the corresponding motor axis parameter. It must be taken into account that different electric motors have axles of different diameters. The considered grinder can be used to process both wooden and metal surfaces including body work.

Motor and polishing discs

Remember that the functional parameters of such a homemade grinder are determined by the individual parts from which it is assembled. In this regard, you should use an electric motor from a fan, since the engine from a computer has less power, which may not be enough for some types of work. In addition, sandpaper discs are not optimal devices of this type. Instead, you can purchase branded circles not large diameter, for example, for a drill.

Can DIY and more powerful stationary version grinder. It can be used with an engine washing machine and equipped with large diameter grinding wheels. In addition to polishing, grinding and abrasive discs can be installed on such a device.

Belt sander

The working element of machines of this type is an abrasive grinding belt. Operating principle tape devices consists in the rotation of an abrasive belt connected in a ring, driven by an engine through a transmission and drums. One of the drums is the leader and the other is the slave. The first of them is driven by an electric motor through a transmission, usually represented by a belt drive.

Some belt grinders are equipped with a device that allows you to change the speed of rotation of the main drum, which provides a variety of operating modes. The tape can be located on the frame vertically, obliquely or horizontally, depending on the purpose of the device. To adjust the degree of its tension is a tension roller. Since grinding operations are characterized by the release of a large amount of dust, it is desirable that sanding machine was equipped with an exhaust device.

It must be taken into account that many design features grinding machine, such as, for example, the diameter of the drums, rotation speed, grain size, the size of the abrasive belt, the design of the desktop, which determine the main functional parameters of the device in question, are selected depending on its purpose. The following variants of working surfaces are classified, for the processing of which grinders are oriented: curved, flat, edges and ends, intermediate layers of paintwork.

What to make a grinder from?

You can create a do-it-yourself belt grinder based on an industrial design, which provides for the movement of the belt over the flat surface of the desktop with the abrasive part out. Wherein homemade device will differ from the branded counterpart large sizes and fixed installation. For these works, you will need an electric motor, for example, from a washing machine, a wooden or metal panel, chipboard, abrasive tape material, glue.

Since the transmission in the form of a gearbox or a belt drive significantly complicates the design of the tool in question, on homemade models try not to use it. To do this, you can equip the device with an electric motor with a power of 2-3 kW with a rotor speed of 1500 rpm.

In this case, with a drive shaft radius of 10 cm, the belt will move at a speed of about 15 m/s. It should be borne in mind that the design in question does not provide for the adjustment of the belt rotation speed. However, it is possible to adjust the degree of its tension due to the fact that the tension shaft, which rotates on bearings to reduce friction, is fixed on a fixed axis, which can be shifted relative to the working table. The drive shaft is fixed on the motor shaft.

The desktop for such a grinder can be made with your own hands from wooden beam or sheet metal. It should be borne in mind that metal options allow you to process more complex objects. The dimensions of the working table of the tool in question are determined on the basis of the dimensions of the tape and the distance between the axes of the shafts, as well as its purpose. Bevels should be made near the rollers in the working table in order to ensure smooth contact of the tape with it.

Drums can also be made by hand. Chipboard can be used as the starting material for these elements. Squares with side lengths of 20 cm are cut out of the slab in such an amount that their total thickness when superimposed on each other is about 25 cm. Then these blanks must be turned into disks with a diameter of 20 cm by processing on lathe. You can process the cut fragments separately, but it is more convenient to grind them all at once, putting them on the axis and holding them. In this case, it should be taken into account that the drums must have edges of a larger diameter compared to the central part in order to automatically hold the tape.

Where to get tape?

The sanding belt can be made by hand on the basis of paper or fabric. The second option is considered more preferable. The fabric can be represented by coarse calico or twill. It should also be taken into account that the rare filling of the belt with abrasive grains, which is less than 70%, makes it possible to reduce the degree of filling it with dust during operation.

The main characteristic of the abrasive belt is the grain size. This parameter is determined based on the number of sieves through which they can leak. According to the grain size, abrasive belts are divided into coarse-grained (12-80), medium-grained (80-160), fine-grained (160-4000).

Abrasive grains can be represented by artificial materials or minerals with high hardness, such as, for example, silicon carbide, corundum. They are fixed on the base by gluing or electrically. In the first case, the grains are evenly poured onto the base surface, previously coated with an adhesive in the form of synthetic resins or skin glue. Electric field used to orient abrasive grains with sharp edges upwards, which increases the functionality of the belt.

The belt for the grinder can be made by hand from sandpaper in the form of rolls, which are cut into fragments of the required size.

In this case, it should be borne in mind that the length of the tape is determined by the method of fastening the ends of the cut fragment. It is possible to connect them at an angle, butt and overlap. In the first case, the ends are cut at an angle of 45 ° and a linen overlay is glued under the joint. Lap joint suggests preliminary cleaning hot water a fragment of one of the ends 8-10 cm from the abrasive grains. Then the cleaned area is covered with glue and applied to it. back side the other end of the tape and compress the junction. The optimal thickness of the abrasive belt is 200 mm. A 1 m long roll of raw material is enough for 5 tapes.

The bed must be cut with your own hands from a thick sheet of metal. At least one of its sides must be evenly cut to secure the platform with the electric motor by screwing it with three bolts through the holes pre-drilled in the frame.

Even if you purchase and install the necessary accessories on the angle grinder, this does not mean anything. Treatment different materials requires certain knowledge. Without this, it will be difficult to achieve the desired quality.


Such a question can be perplexing, because this is the angle grinder - an angle grinder. But it is very versatile and must be prepared for each operation. To prepare the grinder for grinding, you need to purchase a support wheel, which is installed directly on the machine shaft.

For wood processing it is necessary to stick emery on this circle. The number of sandpaper is selected for the immediate moment of work. On sale you can find grinding wheel the desired diameter, and emery wheels of the appropriate size. Velcro emery wheels are also available for sale, which are very easy and quick to change on the tool.

To convert our concrete grinder, it will be good decision purchase a special protective dust cover. It is good in that it has a pipe for connecting a vacuum cleaner. Known casings are manufactured by Hilti. On the casing of this company there is a shiftable sector, which opens up part of the wheel for grinding in the corners.

Metal grinder grinding is usually performed with standard metal grinding wheels. They have different diameters, different thickness and different grain of the grinding surface. But, if you are going to sand an obscenely rusted surface, then first you need to go through it with a metal brush. Such brushes of the required diameters are also on sale.

How to grind with a grinder


We must not forget that grinding is always associated with large quantity dust. In preparation for grinding, do not forget about yourself! A protective mask and respirator are the best assistants when grinding. You can also find such an option where the mask is combined with a good respirator.

The respirator filter will clog very quickly, so you need to prepare several pieces at once for quick replacement. Only after thorough preparatory work, you can start grinding.

Sanding wood + (Video)

tree it unique material. It is polished by hand well, but with a grinder you can achieve very good results. Some snobs claim that it is impossible to grind with a grinder at all, but this is from ignorance and inability.

The main secret is that the grinder is used at minimum speed. If the grinder has a speed switch, then there will be no problems. At high speeds, the sandpaper will clog the wood very quickly and very tightly. In this mode, it is not enough for five minutes of work. The optimum speed is not more than 6000 rpm.

Another secret is not to grind the entire area of ​​the circle. If you sand the entire surface, then circular marks 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. The movements of the machine should be along the grain of the wood.

With this method, you can get excellent results when grinding lining. The board becomes smooth and leaves no tool marks. Do not just get carried away and change the emery pads on the circle in time.

The log house is polished in a similar way. Here it is desirable that the support plate be thin at the edge. With such a plate it will be easier to grind the narrow places where the logs join. Otherwise, this work will have to be finished with a chisel.

We work on concrete + (Video)

If it was not possible to purchase a branded protective dust cover with a nozzle for a vacuum cleaner, then you can do it yourself. To do this, we take a used bucket from under the putty or glue with a diameter slightly larger than the circle of the grinder. We cut off the bottom part at a height slightly larger than the assembled grinding part.

We cut a hole in the bottom for installation on the gearbox and a hole for a plastic plumbing corner outlet. Now we connect the vacuum cleaner hose to the nozzle and work quietly.

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

When grinding a concrete floor, it is necessary to constantly control the plane with the help of a construction ruler, because due to the different density of concrete, recesses can be made. For the processing of butt joints between concrete pours, it will be sufficient to achieve one level combination.

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

Grinding metal surfaces + (Video)

The metal is polished according to different requirements. Most often, the metal is ground for painting or for further polishing. The main tool is a support cup with replaceable emery pads. The selection of sandpaper depends on the degree of processing and on the condition of the metal.

During grinding, it is necessary to work only part of the disk. There should be no untreated areas on the surface.

It is desirable to coat the treated surfaces of ordinary steel with a primer. Moisture in the air can coat the metal very quickly and cause rust.

When working with wooden surface comes to an end, the stage of finishing grinding begins. To perform sanding without burrs, scratches, round off nicely sharp corners any detail, you must use a wood grinder. This tool will help you perform professional grinding even for a beginner who first took the device in his hands. If you wish, you can make a grinder yourself, using only improvised means.

The industry produces several types of machines that differ both in design and purpose. Here are the main ones:

  • Eccentric or orbital, in this case the sole of the tool simultaneously rotates around its axis and along some orbit. It turns out that each time it passes in a slightly different place, so scratches and burrs are rubbed off with each pass more and more.

  • vibration model. Here, the working sole carries out reciprocating movements with a frequency of about 20,000 movements per minute. It is due to these movements that grinding occurs.
  • Angle grinder, which is popularly called the "grinder". With the help of this tool, rough processing of parts, large logs, etc. is carried out. For processing, abrasive wheels of the required grain size are used.
  • Belt sander, which is usually used for work on large surfaces. Structurally, it consists of rollers driven by an electric motor, on which an emery tape is put on.

Making a belt sander with your own hands + (Video)

Making a belt sander yourself is not at all difficult, you must perform the following steps:

  • pick up suitable materials and details;
  • make a reliable basis for fixing the tool;
  • install a suitable countertop;
  • fix vertical racks with a tensioner and a drum;
  • mount the motor and drums;
  • fasten the sanding tape.

To handle pretty large parts and elements it is necessary to make a large copy of a serial grinder. For example, if you take an electric motor with a power of 2 kW or more powerful with a rotor speed of 1500 rpm, then the gearbox can be omitted. The power of such an engine is quite enough to rotate a drum of about 20 cm in diameter and process parts of about 2 m.

You can also use Electrical engine from the old washing machine. The bed in this case is made of a thick sheet of iron, having prepared a place for installing the motor and carefully fixing it with bolts to eliminate vibration. The design of such a machine consists of 2 drums, one of which is fixed, and the second can be stretched and rotated on bearings around an axis. The basis for the machine is preferably made of metal or several sheets of thick plywood. Drums are made on a lathe from chipboard. The tape is cut from sandpaper cloths with a width of about 20 cm and fixed on the frame. The larger the table dimensions, the larger parts can be stacked and processed in the future. Blueprints finished products can be found on the web.

We make a grinder from a grinder

Many may say that the “grinder” is the same as an angle grinder, but there are some subtleties hidden here. It should be borne in mind that the angle grinder has very high speeds and often quite a decent weight. To polish the surface with a grinder, you must have considerable experience in this matter and use special polishing discs and circles. The grinder has a much lower engine speed and weight. To work with a factory grinder, certain experience and skill are not required.

It is possible to independently make a good grinder from a grinder, which is not inferior in its parameters to a factory machine, only by refining it electrical circuit, by mounting the regulator at a lower speed and by using special grinding attachments.

We make a grinder from a drill

To turn an ordinary, household electric drill into a grinder, you need to equip it with a special nozzle - a working drum or a special support plate, depending on the task.

The support or grinding plate is a plastic or rubber base with glued sandpaper and a shank for clamping into a drill chuck. Flexible shaft cymbals are suitable for working with a loose drill, while rigid shafts are best used only for a well-fixed drill.

Sanding drums for household drill Structurally, they are an ordinary cylinder, a shank and sandpaper glued to the cylinder. When using drums working surface grinders is located parallel to the axis of rotation.

Making an orbital sander

Currently, you can make an orbital machine with your own hands only from a broken orbital machine. This is due to the complex device for rotating the working disk, which is quite problematic to repeat on its own. It should also be borne in mind that a machine made by a specialized company will not cost too much, and it will be very difficult and time-consuming to make it yourself.

We make a grinder from a computer hard drive + (Video)

Any used hard drive can be turned into a miniature grinder. To do this, follow these steps:

  • completely disassemble the hard drive and remove from the case everything that is located to the left of the magnetic disks;
  • cut a working circle from sandpaper, make a hole for the spindle in the center of the circle;
  • stick several strips of double-sided tape on the rotating disk of the hard drive and fix sandpaper on it;
  • make a protective screen that protects the eyes from the possible departure of the manufactured emery disc;
  • to plug finished structure to the power supply from the computer and use.

Of course, this design does not have high power, but it is quite possible to sharpen a small knife or scissors.

When working with wood, the final step in processing the material will be grinding. A grinder will help you with this. There are many different models on the market, but if your budget is bursting at the seams, you can make such a machine yourself.

How to make a grinder

Do a simple typewriter can from hard drive your PC. To do this, you will need the hard drive itself, an abrasive, a PC power supply. It will be designed to work with small details. When disassembling the disc, stick the abrasive on a rotating plane. After that, the structure must be connected to a power supply unit (power supply), and then the entire structure must be fixed on the working plane of the table, provided with a speed controller and a switch.

DIY wood grinder

Grinding machines are represented by the following types:

  • eccentric or orbital;
  • vibration;
  • corner;
  • tape.

When making a machine, you will need:

  • electric motor;
  • source of power.

The power unit must be taken from household appliances, for example, from a fan, the power supply is computer, the battery is household. As a basis for the above elements, a wooden board is suitable, on which the battery with an electric motor should be fixed with screws. The start button must be attached to the base with self-tapping screws. The wire strands are fixed with staples of an industrial stapler.
The working part of the tool is a grinding wheel, which can be purchased independently. The abrasive disc will be driven by an electric motor using two bushings.
You can strengthen the design of the device if you take the motor from the washing machine as the engine. In addition to polishing discs, in this case, grinding and abrasive discs can be installed on the tool.

Homemade belt sander


An abrasive belt acts as a working element in this type of device. A do-it-yourself machine will be stationary, and have large dimensions compared to an industrial design. For the manufacture of a sample, it is best to use a power unit with a power of 2–3 kW and a rotor speed of 1500 rpm.
The radius of the drive drum directly affects the speed of the belt. The larger it is, the higher the speed of the tape. Homemade construction will not allow you to adjust the speed of the tape, however, you can influence the tension force by shifting the fixed axis of the tension shaft, mounted on the motor shaft, relative to the desktop.
Workbench for grinder must be made of wood or metal. A sander belt can be made from abrasive paper available at a hardware store.
The working element, which is the emery belt, is set in motion with the help of a transmission and drums by a power unit. Shafts are divided into driving and driven. Drums can be made using chipboard sheets, turning them on a lathe so that the result is disks about 20 cm in diameter. When processing, one thing should be taken into account: the edges of the shafts must have larger diameter, compared to the central part, to automatically hold the tape. The dimensions of the rack will depend on the width of the tape and the distance between the shafts. At the location of the shafts in the canvas, it is necessary to make slots for the smooth passage of the tape.

How to make a mini grinder with your own hands

First you need to find foam to prepare the base for the device. After that, you need to cut a hole for installing a switch in it. Then you will need electrical tape and a power source, for example, the well-known Kron battery. We fasten the battery (Krona) to the foam base with electrical tape. We take a stopper from under champagne and a core of the handle. We cut the rod to the desired length, after that we put the handle rod on the cork with a blunt end and insert the tip of the rod into the hole for the motor shaft. After that, you need to cut a strip of abrasive tape to fit the size of the cork with scissors. After you cut the tape, it should be glued to the cork around the circumference. This cork construction will be the working part of the machine. We carefully inspect all the wires and connect them with twists, isolate the connections with electrical tape. We try to start the resulting device. Now you have your own mini car. Such a device is useful for performing simple small jobs for which a conventional grinder would be too large and inconvenient. If you are an observant and patient, as well as a diligent person, it is not difficult to make a grinder with your own hands. To do this, you only need dexterous hands and a little patience.

grinder functions.

The drill is good because it changed the nozzle, and got new tool. Now we will talk about using your impact drill as a powerful tool for processing various surfaces.

Rough surface finish.
For cleaning wooden and metal surfaces from paint, varnish, rust special nozzle on a drill, which is called a bowl-shaped twisted cord brush. It looks like this:

When using a cord brush, follow these guidelines:
- Clamp the cord brush securely in the chuck.
- Work the whole plane.
- Do not press the cord brush too hard on the surface.
- Do not exceed the speed indicated on the cord brush.
- Hold the drill securely and firmly in your hands.

Softer surface finish.
The same treatment, but softer, is applied with a different cord brush. This is how it looks installed in your drill:

Grinding surfaces with sandpaper.
If you need to sand a surface or part, for example, to remove splinters from wooden block, then, cutting out a circle of sandpaper, and putting it on a special device (grinding disc), you will do it with ease. This is how the fixture installed in the drill looks like:

However, this is not the end of the matter. If you don’t have time, or you don’t want to cut circles out of sandpaper yourself, and then put them on a fixture, you can buy self-adhesive sanding discs for a drill. True, in this case, you need to purchase another device called a “support grinding plate”. You take a plate, stick a sanding disc to it with Velcro and install it in a drill. Everything, you can start grinding:

The fantasy of the master is very rich. Below is a nozzle called "radial petal disc". Each petal of such a disk is made of sandpaper. Also applicable for grinding after installation in a drill:

Polishing surfaces with a sponge.
Together with the support plate discussed above, a polishing sponge is also used. The polishing sponge is attached to the base plate with Velcro. You install this nozzle in a drill. Everything, the polishing tool is ready. You take a polishing paste, apply it to the surface to be polished, then turn on the drill and start rubbing the polish with a sponge attached to the drill:

Knife sharpening.
In stores you can also find radial grindstone for a drill that can be used, for example, to sharpen knives. This is how the grindstone looks like installed in a drill:

Screwdriver functions.

Classic screwdriver.
A soft start drill that can be successfully used as a screwdriver at slow speeds. For these purposes, a special “bit holder” nozzle is used on the drill. The holder is installed in the drill, and then the corresponding bit for the self-tapping screw is installed in it. In this way you can successfully spin fast a large number of self-tapping screws, which is of course important during repairs. If your drill has a reverse, then you can unscrew these screws. If your drill has a shock impulse moment, then it can unscrew even completely ancient self-tapping screws that have long been stuck in the wall, in which the slot for a screwdriver has been ground off. Therefore, I highly recommend looking for a drill with this additional feature.

Screwdriver for hard to reach places.
There are times when it is quite difficult to tighten or unscrew the screw (masters say “do not get close” to the screw).

Grinding accessories

True, this is more common in a car, but also with the usual apartment renovation this may be encountered. So, for tightening and unscrewing screws in hard-to-reach places, a special nozzle is used on a drill, which is called a “flexible shaft extension”. One end of the flexible shaft is fixed in a drill, and the other is a magnetic holder for bits. You install the desired bit in the holder, and now, your tool for tightening screws in hard-to-reach places is ready:

Mixer functions.

When you really get into renovation work, then you will face the fact that you will constantly need to knead something: wallpaper glue, cement-sand mixture (CPS), floor leveler, glue for gluing tiles, plaster, putty and more. Let me tell you right now, you can't do it by hand. Firstly, you will quickly get tired, and secondly, you will never be able to mix cement mortars with your hands to the state of thick, even sour cream! Therefore, a drill with a mixer comes to the rescue. The mixer looks like this: Installed in a drill, the mixer looks like this:

How to work with an impact drill

Before you start working with an impact drill, you need to set up the tool and prepare everything you need for work. Now I will talk about my drill, but for other drills the principle will be similar.

Setting the operating mode.
First, realize what kind of work you have to do. The impact drill has only 2 main modes - this is the drilling mode and the chiseling mode. In accordance with this, you need to set either a “drill” or a “hammer”. I note right away that you set the hammer only for the drill to work in the hammer drill mode. In other cases: drilling, grinding, tightening screws, mixing cement mortars is carried out when the switch is set to the “Drill” position.

Speed ​​setting.
For different types works you will exhibit different speed. For example, if you need to drill holes in a metal plate that you want to use for a bracket, then it is better to turn on the 2nd speed. If you are going to knead cement mortar or want to tighten the screws, you must set the 1st speed. If you are going to work with a cord brush, then usually when buying nozzles, the recommended speed is indicated on the package. Thus, you can navigate in the choice of speed. If suddenly you don’t know at all what speed to set for a certain type of work, consult with professionals.

Reverse setting.
For all types of work, except for loosening screws, the direction of rotation of the drill chuck should be clockwise. To do this, the reverse switch must be set to the position where the arrow points to the cartridge.

Nozzle installation.
Depending on the nature of the work, you install the desired nozzle on the drill. I have told you about attachments throughout this book. So just take a look at the right section.

During work.
The drill is started by gently pressing the start switch. (See Impact Drill Construction). Moreover, the harder you press, the faster your drill accelerates. With the strongest pressing, the maximum speed will be the one that you set when choosing the mode: “1st speed” or “2nd speed”. In this way, with the start switch and speed change, you achieve a very wide speed range. If you are drilling a surface for a long time and are tired of pressing the start switch, then for this purpose, press the "Lock Button" by releasing the start switch. In this option, the drill will continue to work. This is convenient, because saves your energy. You can disable this mode by pressing the start switch again.

Finally, if you are unscrewing the screw, then set the reverse switch to the position where the arrow points towards your hand. When the drill is smoothly turned on, the chuck should rotate counterclockwise.

Dangerous experiments

The impact drill will be your indispensable friend and assistant in a variety of jobs. But, nevertheless, there are things that are unacceptable in operation, and I will briefly talk about them now. We are talking about a circular saw blade, which, for some reason, some also want to install on a drill, thus constructing an electric saw:

Remember the rule: saw blade do not put on a drill. First, because there is no protective cover. Secondly, there will be no necessary pressure on the material being processed. In the third, the drill will “walk” in the hands, and if the saw lies unevenly on the surface being sawn off, then either the disk will fly apart, or the drill will be pulled out of your hands, and no one knows where it will fly! Injury guaranteed! This is very dangerous and let's not experiment like that!

Finally

As you gain the necessary experience with an impact drill, you will likely want more. The first thing you will encounter is that you will not only need to make a hole in the wall for a dowel, but, for example, completely drill a thick wall with a drill with a diameter of 10 or 13 for laying wires. It will be difficult to perform such work with an impact drill. Do not mock her, otherwise she will quickly fail you. In these cases, of course, use a perforator.

The second point is the speed of work during the repair. If, for example, you are expecting a global installation of drywall on all walls in the apartment, then of course, in addition to the impact drill, it is not a bad idea to purchase a screwdriver separately. The fact is that you will constantly hammer the wall and wrap screws. Moreover, you will alternate these two types of work so often for a long time that for a moment it will seem to you that you are only doing that you are changing the drill for a screwdriver. Therefore, having at hand a separately charged impact drill and a screwdriver, the efficiency of installing drywall will increase significantly. There is one more secret: a screwdriver weighs lighter than an impact drill and, of course, it is more convenient to wrap it.

However, if you are new to repair, I don’t want to burden you with expensive purchases right away and tell you purely my experience, which began with a hammer drill and I think that this sequence of mastering the tool is the most correct. You ask, or maybe just buy a hammer drill instead of an impact drill. I answer. A hammer drill is even heavier than an impact drill, and now it will not be at all convenient to use it as a screwdriver or surface grinder. Take it as a rule: a puncher is needed mainly for chiselling walls.

Nozzle for a drill for grinding

If you think that a drill can only drill holes in the walls, you are mistaken.

Hammer drill. Functions and setting

This tool is quite versatile thanks to great choice accessories for it. For example, it is worth buying a sanding attachment for a drill, and you can sand almost any surface.

Varieties of grinding nozzles for a drill

There are over a dozen different drill bits on the market. Each of them is a rod and a grinding material fixed on it. And depending on what kind of material it is (sandpaper, felt, abrasive element), you can grind the surface from one or another material.

Here is a list of the most popular grinding attachments:

  • plate - can be plastic, rubber, etc .;
  • cup - with brushes or soft filling;
  • disk - with soft or metal packing;
  • drum - with an emery tape, there may be several subspecies;
  • fan - with sandpaper elements;
  • end - in the form of cones, drums, washers, made of soft and hard materials;
  • soft polishing discs.

A wood sanding drill bit is usually a cup type bit with stiff metal bristles. The lighter ones are made of brass. Also, a similar attachment for a drill is used for grinding metal and removing corrosion and paintwork from metal surfaces.

For metal surfaces, drum nozzles are also used, on the side walls of which sandpaper is attached. These nozzles can be processed round holes and shaped parts made of wood and metal.

Fan nozzles for a drill are made in the form of a disc for grinding metal with pieces of abrasive material fixed on their edges. They are easy to handle hard-to-reach places and grind internal cavities in small holes.

A drill attachment for grinding walls with fine sandpaper can speed up the process of leveling walls after they have been plastered. This method is more budgetary compared to the purchase of a grinding machine. However, it has drawbacks - the drill overheats rather quickly, and there are fears that the nozzle may simply fly off in the process. In a word, grinding walls with a special device is more convenient and safer.

In addition to buying nozzles for a drill, you can make them yourself, thereby saving even more on working tools.
