Which type of luggage is most optimal for you?

A screwdriver is a universal and multifunctional power tool that can be used to perform many tasks :

Cutting materials - metal sheets, ceramic tiles, stone, plastic, metal-plastic and metal pipes, as well as concrete products;
Straightening and cleaning of welded materials;
Removal of corrosion paint, plaster residues;
Processing grooves for inserting cables or pipes in brick or concrete walls.

How to choose a bargalka: important features

When buying a grinder , it is important to determine in advance for what purposes and how often you plan to use the power tool . Depending on the intensity of use, all angle grinders can be divided into three classes:

Household - this type of grinder is designed for home use. These are small (up to 1000 W) power tools, the engine of which is not designed for long-term continuous operation. Due to overheating, the grinder may automatically turn off.

Another important advantage is compactness, as they have a low weight (on average up to 2 kg), which makes it convenient to work in hard-to-reach places.

Professional - a very productive and powerful (over 2000 W) model, designed for continuous and long-term use. To increase the tool's operating time, various engine cooling options are provided (ventilation, use of special materials with increased heat transfer), as well as high-quality special materials, etc.

Such models have greater weight and dimensions, and in the vast majority, there are handles designed for two hands.

Semi- professional - in terms of characteristics, they occupy an intermediate position between household and professional models. Sufficiently powerful models (up to 1500 W) can be used for long-term work.

Bargalka disk dimensions

The size of the disc is the main characteristic of the device, which determines how deep the cut can be made. The minimum size of the cutting disc is 115 mm, and the largest is 230 mm.

The most popular are several disk sizes :

125 mm - the most popular size, used in most household and professional models. The 125 mm disc grinder is very light and can be safely used with just one hand.

150 and 180 mm - a compromise option, designed for both grinding and cutting.

230 mm - the maximum diameter of the disc, which is designed for very powerful saws. With such discs, it is possible to cut pipes, bricks, concrete, but sawing with such a tool is not very convenient, because due to its heavy weight, its mobility is limited.

You should purchase 230 mm diameter grinding wheels if you have large construction or volume work to do.

In addition, there are several other factors to consider:

The quality of the cut with a thin disc is better than with a thick one, but at the same time, a thin disc is not suitable for long-term cutting. Due to friction, the disc wears out very quickly. Therefore, its thickness is selected based on the depth of the cut.

The larger the diameter of the circle, the lower the speed at which the bargalka should operate. Wide (230 mm) discs are designed for no more than 6.6 thousand revolutions, medium (180 mm) - for no more than 8.5 thousand revolutions, and small (115 - 125 mm) - for up to 11 thousand revolutions.
