⚒ Best Brush Sanders in 2020

Before using a product made of metal, wood, before applying varnish, paint, it is required to carry out work on grinding, polishing the product. It is difficult to do it yourself, especially when it comes to large, flat surfaces, removing a millimeter layer of material is difficult. Here the master will come to the aid of a grinding machine, brush type. The editorial staff of the site "bestx.htgetrid.com/en/" offers you an overview of the best brush grinders in 2020.

What is a sander

Since the time of the first builders, the question has periodically arisen of how to give the treated surface a digestible, aesthetic acceptable look. After all, sitting on a bench made of roughly hewn stone or a tree of pleasure, to put it mildly, is not enough. At first, for such purposes, sandpaper of various grain sizes and a plane were used. But modern construction, with its large-scale work front, required more powerful apparatus, with minimal use of manual power. These are the power tools, among which grinders play an important role.

What are the grinders

The entire instrument, and electric is no exception, is divided into three types:

• Amateur - for housework;
• Semi-professional - the most affordable type of tool in relation to its capabilities;
• Professional is the most expensive, high-quality type of instrument.

When it comes to grinding machines, a highly specialized tool, then buying an amateur model can be a mistake. Indeed, for finishing the surface, albeit a large area, once a year to buy a power tool, even of a household type, which, of course, will not gather dust on the shelf the rest of the time. Hand grinding is applicable here.

When a question arises, how to grind a wooden or even metal surface at home, a homemade installation can help. It consists of a screwdriver or drill with a fixed disk on which sandpaper is glued. Such, albeit a primitive tool, will last one season, which is quite enough during an amateur repair or with a one-time processing of a wooden surface. If regular grinding of the material is supposed, one cannot do without electrical devices. The most common types of electric grinders are:

1. Corner - irreplaceable when it is necessary to polish hard-to-reach places.
2. Eccentric - another name for them, given by the principle of disk rotation, orbital. These models consist of a circle, on which an emery wheel is put on with the help of velcro, the grain size of which can vary as desired. The disc makes rotational vibrating movements, and the dust formed from grinding, in some models, is taken away with a special bag. Powerful, professional models designed for many hours of work are equipped with a separate vacuum cleaner, which allows you not to be distracted during work by cleaning the formed dust from the surface of the polished item.
3. Belt - their design consists of two cylinders between which an endless sanding belt is stretched.The belt, rotating at a speed that is adjustable by the user, polishes the surface of the material. What is the difference between a belt polisher and an eccentric polisher? The difference is primarily due to the sanding belt format. In tape machines, it is flat, the width of the web is large, which makes it possible to apply more force to the surface. Therefore, such systems are used mostly for rough work, for example, in car body repair. However, most of all the sanding skin of a belt sander affects the center of the surface, while "bald spots" remain on the sides. Eccentric ones work more evenly, removing unnecessary with a thin layer.
4. Polishing - used for finishing, polishing robots.
5. Brushes - similar in their structure to ribbon ones, they are used, among other things, on wood in order to artificially age it. But the devices of such a system work more accurately, more evenly than the tape machines, penetrating with the bristles of the roller into hard-to-reach places that are not attainable for tape machines.

We will describe the latter, brush systems below.

How a brush sander works

The internal structure of a brush grinder (SHSHF) is schematically little different from any other and consists of:

1. Housings are an outer shell that protects the mechanical and electrical components from the external environment. The body is equipped with handles guiding the SHM and pushing it. The best manufacturers use shock-resistant plastic, aluminum, and alloys from it as the body material.
2. The electric motor is the "heart" of any power tool. The engine power determines the capabilities of the SHM, the duration of operation without stopping and directly affects the price of the model. Electric motors are either battery or AC powered. The first ones are distinguished by increased mobility, the scope of work is not limited to the length of the cord, but the maximum power of such models is low. And besides the fact that the battery will require constant recharging, you should be prepared for the fact that it will regularly have to be replaced with a new one. After all, batteries in such instruments do not "live" for a long time. The latter have a greater number of engine revolutions, high-level models also have a starting current limitation, for smooth acceleration from scratch, without jerking. The disadvantage of the same ShchM, operating from alternating current, - the length of the cord dictates the possibility of their use.
3. The mechanical part - gearboxes, on which the speed of rotation transmitted to the shafts depends, the shafts themselves, the drive cylinders, whose value affects the ability of the grinding surface to pass through the material being processed.
4. Control elements - switches, knobs on which adjustment of engine speed, safety systems depends.
5. Attachments - on which the sanding belt is put on with the help of clamps.

What to look for when choosing a brush sander?

Before choosing a SHM, you should decide how often you will use it, what kind of material, what type, is supposed to be processed. For one-time use, for the purpose of cleaning from rust, scale, battery models are suitable, because their dimensions allow not only processing hard-to-reach, small surfaces, but also not taking up much space during storage. A great choice if you have a home renovation.

Construction, semi-professional, especially professional ShShM works much longer, more efficiently, allows you to install a lot of nozzles, take away the resulting debris to the side. But the average price of such a model is about 30,000 rubles, which will pay off only with regular use. An important question is which company is better to buy such a power tool. First of all, you should immediately abandon any Chinese, little-known companies. Their products are unreliable, parts are made of low-quality materials, which not only promises a short service life, but also a danger to your health.

The three leaders at the moment are the Western firms Makita, BOSCH and the Russian Interskol.The popularity of the latter's models is due to the excellent price / quality ratio, a wide network of warranty workshops. Alas, the company's recent financial difficulties have shaken the confidence of craftsmen and ordinary users in its products. The last question is where to buy a power tool? The advantage of online stores is that comprehensive information is available to the consumer, there are reviews about the purchased tool, what disadvantages are inherent in it in the opinion of buyers. A sales assistant in a specialized store will help you avoid mistakes when choosing a grinder. He will recommend how to choose the best suitable sanding disc sheet, demonstrate how to work with a power tool.

An interesting feature of the Bosch GSI 14 CE SHSHM is the ability to regulate the engine speed. But if other models allow a change in speed after the end of work or at idle speed, then the Bosch GSI 14 CE allows this during work. For example, when cleaning a stainless steel product. Bosch GSI 14 CE is rightfully included in the rating of quality brush grinders in 2020. Unfortunately, the price of the device, about 35,000, is quite high, and if the question of how much a brush grinder costs you are relevant, it is better to look for something less functional.
