Drill for concrete: types and purpose of the tool

Carrying out repairs in an apartment or office is a troublesome business and requires certain skills. The successful completion of the work depends largely on the quality of the materials and tools used to process them. Particular attention should be given to the tools necessary for labor-intensive and complex work, for example, drilling a concrete wall. The drill for concrete perforator should be chosen, taking into account the thickness of the wall, the size of the future hole, as well as the frequency of its further use. All borons intended for working with concrete can be divided into gently sloping, spiral, screw and SDS drills. The belonging of the tool to one or another kind depends on the degree of boring of the drill.

Also, each drill has a certain size, designed for drilling holes of different depth and diameter. The drilling process is also affected by the angle of inclination of the screw groove made.

Spiral-shaped drill

Such a drill for concrete has a steep spiral of various types. It allows you to quickly remove the dust formed during the drilling process. The spiral-shaped drill is suitable for punching large holes in a thick wall. The most popular spiral-shaped borers for concrete are foreign-made.

Auger auger

Screw drill for concrete is used when it is necessary to make a deep hole. With it, the debris from the resulting hole is removed even faster than when using a spiral device. Another advantage of the screw auger is its simplicity in operation, which is characterized by the absence of the need to grind the tool.

SDS Models

Drills of the variety SDS are indispensable when drilling a particularly strong concrete wall. During this operation, a large impact load is required to obtain a hole of the required depth and diameter, which the SDS drill is capable of providing.

The drill for concrete of SDS-Max type is considered to be particularly strong. Thanks to special soldering on the surface of the tool, it is able to make a hole even in a reinforced concrete obstacle. At the same time, the service life of such a drill reaches several years.

A gentle drill

A shallow drill for concrete is used for drilling small holes of shallow depth. He is not able to cope with very strong concrete. After the work of a shallow drill, it takes a long time to remove the debris from the hole, the drill itself does a very poor job of this task. There is a flattened Boers and an advantage - they are stronger and more reliable than, for example, spiraling.

Purchase Features

In order to choose the right drills for concrete, the price for which can vary significantly, you first need to determine for what purpose it is needed. If you intend to work with thick, strong walls, it is better to buy a screw or SDS-drill. For periodic drilling of small holes for household needs, a gently sloping drill will suffice. The cost of drills varies considerably depending on their quality and ability to cope with strong and thick walls. Simple gently sloping drills can be purchased for 20-30 rubles, the price of reinforced SDS standard models reaches 200 rubles and higher.

In any case, a quality tool can be bought exclusively in a specialized store. And such a drill can not be too cheap. Having saved a little and bought a cheap low-quality counterfeit of a well-known brand, you can significantly complicate your work.
