Rating of the best brush grinders in 2020

One of the most important tools used for grinding parts is the brush sander. What you need to know when choosing such an abrasive tool, and what you should pay attention to when buying it, will be discussed below.

What is an electric sander for?

Recently, when decorating the premises of hotels, restaurants and other buildings, more and more emphasis has been placed on beautiful wooden parts artificially aged with the help of a grinding tool. Many of these ideas are adopted by private craftsmen when working with wooden products. Designers place a particular emphasis on wood elements, adding them to the decoration of buildings on an ongoing basis.

Such projects are quite expensive. Good craftsmen do not charge less than 400 rubles per square meter. m of such a coating, in addition, the cost of the material itself should be taken into account. So aging your favorite wooden part will be quite an expensive pleasure. Of course, you have to pay for the pleasure, but if there is an opportunity to do such a thing yourself, maybe it is worth doing it?

If you are planning to age the facade of the building or completely brush the interior decoration of the room, then the order for such work will come out in a very large amount. But this is not a reason to give up your plans and give up your endeavors. There is special equipment, the purchase of which will not only help to save on interior decoration, but also bring a plus to the budget. In addition, such a tool, being at hand, will help to remake any wooden product in the future. You no longer have to resort to the services of expensive specialists.

What can be done with a brush sander

All kinds of cracks, artificial aging, imitation of tree rings, embossing or cobweb effect - all this becomes quite possible if you use a brush sander. It is for these effects that wood craftsmen love this tool. No other tool can help achieve similar effects, only a sander, using a brush rotating at very high speeds, on which there are many small nylon fibers. Considering that a variety of attachments for such a tool are sold, you can achieve various effects when working with wood. Here are just some of the ways to use such a tool:

1. It is possible to remove old paint coatings while renovating the facade of a house.
2. The effect of old wood is created when updating the interior on a lining or wood.
3. When working on the restoration of old furniture, special attachments will help to remove old, loose layers of wood.
4. To achieve a two-tone finish when working with specially fired wood.
5. Self-made furniture with antique effect.
6. You can age the decorative elements of your home.
7. Manufacturing of special interior elements, such as lamps and lanterns.

Working with metal

If it is necessary to work with various metal or aluminum products, then such a grinder will also be very needed. The main thing is to choose the right grinding wheel, because it will be different for each material. For what purposes such a tool is used:

1. Remove old, unnecessary paint, varnish and putty.
2. You can clean the surface of a metal product from rust.
3. Product polishing, hiding and removing all kinds of scratches.
4. Cleaning the product from a variety of contaminants.
5. The metal product gets a matte effect.

When processing metal, metal bristles will have a more gentle effect on the product than abrasive materials. As a result, the old metal is compacted, small pores are tightened and closed, and the part becomes more resistant to various physical influences.

The principle of operation and device design

The product is produced in two types. This is a plane construction and a device made in the form of a grinder. The first option is for large perimeters. In this case, it is convenient to hold the device with your hands and control it at high speeds. The second option is intended for sanding hard-to-reach surfaces. It is convenient to handle edges and corners with such a tool, since in this design the brush is taken out separately. The device has become widespread among consumers.

The mechanical part of the brush grinder is driven by an electric motor. A small roller is used as a working element, which consists of a large number of small fibers. The bristles are made of metal or nylon, the choice depends on the type and nature of the surface to be treated. On a positive note, the grinder has a speed control. Metal processing requires a high roller speed. You can grind wood at low speeds. The start button has a latch. With it, you do not need to hold down the button during operation.

Most machines have a dust extraction system in the design. It can be an ordinary bag or a vacuum cleaner. It is much easier to work with the dust extraction system, because there is no dust cloud around the worker and there is no need to wear protective equipment. Also, cleaning will take less time.

As the brush passes over the workpiece, the tough bristles grind the brush through the rotation and pressure of the operator. They change the structure of the metal, removing the less resistant layers. After processing, the surface takes on a completely different shade. With wooden products, everything is easier. After sanding, they are impregnated and painted. Here you can choose a variety of colors. Metal processing nozzles have different compositions. They can be selected in such a way that the part will have a mirror surface.

The better the brush design

Many people ask themselves the question "is a sander needed at all?" After all, the nozzle roller can be installed on the drill and also processed the surface. Many masters do just that. But the end result is not always what you want.

With a simple round brush, the contact area is very small. Therefore, it will take a long time to grind a tiny piece of wood. This method is suitable if the master makes small decorative elements (candlestick, stand, frame). To process a large solid wood (table top, bench), you will need a different tool.For large jobs, a brush sander is the best option. In one pass, it will take the width of the treated surface from 100 to 150 mm. It will be several times faster and more efficient. The end result will not disappoint.

The device must be selected taking into account the functions performed

It is necessary to determine the quality and composition of the treated surface. You need to understand which brushes will be used. After that, you can take up the selection of the unit. The first step is to study well the instructions and technical characteristics of the proposed products:

1. Power - selected depending on the material being processed. For grinding wood products, a large indicator is not required. An 800-850 W power unit will be enough. Metal processing requires a lot of effort and expense. Therefore, the device must have a power of about 1500 W.
2. Rotation frequency. Grinding brushes come in different diameters. To spin them up, the electric motor must make some effort. The larger the circle diameter, the higher the speed should be. For many devices, the speed reaches 3000-4000 rpm. However, an important point is the presence of a speed control on the device. In this case, the machine can be configured both for grinding iron and for processing wood. Maximum values ​​are usually set for metal. Wood can be sanded at 1000 rpm.
3. Working element diameter. The instructions usually indicate the dimensions of the brush. The larger it is, the faster and more efficiently the device polishes the work surface. So for the treatment of walls and voluminous metal surfaces it will be more profitable to buy a working element with a diameter of 12 cm and a length of at least 10 cm.For working with small products, a roller 6 cm long is suitable.
4. Weight. Devices weighing 2-3 kg are on sale. It is easy to work with such devices for a long time. With their help, it is easy to process surfaces in any position (for example, a baluster for a staircase can be polished from below and from above). Larger tools reach a mass of 4-5 kg. Such units will be more profitable to process large flat surfaces that are in a horizontal position. In this case, the mass of the grinding machine will facilitate the work of the master, since he will have to apply less effort when pressing the tool with his hand. The brush itself will bite into the surface of the material under the weight of the product body.
