Carrying out repairs in an apartment or office is a troublesome business and requires certain skills. Successful completion of work largely depends on the quality of the materials and tools used for their processing. Particular attention should be paid to the tools necessary for labor-intensive and complex work, for example, drilling a concrete wall. A drill for a concrete puncher needs to be selected, taking into account the thickness of the wall, the size of the future hole, as well as the frequency of its further use. All drills designed for working with concrete can be divided into flat drills with a steep spiral, augers and SDS drills. The belonging of the tool to one or another type depends on the degree of inclination of the drill.
Each drill also has a specific size for drilling holes of various depths and diameters. The angle of inclination of the helical groove made also affects the drilling process.
Spiral drill
Such a concrete drill has a steep spiral of various kinds. It allows you to quickly remove dust generated during drilling. The spiral drill is suitable for punching large holes in a thick wall. The most popular spiral concrete drills are of foreign manufacture.
Auger drill
Auger drill for concrete is used when it is necessary to make a deep hole. With it, debris is removed from the opening even faster than when using a spiral device. Another advantage of the auger drill is its ease of use, which is characterized by the absence of the need to sharpen the tool.
SDS Models
Drills of the SDS variety are indispensable when drilling a particularly strong concrete wall. During such work, a large shock load is required to obtain an opening of the required depth and diameter, which the SDS drill can provide.
Particularly strong is considered a concrete drill like SDS-Max. Thanks to a 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 life of such a drill reaches several years.
Gentle drill
A flat concrete drill is used for drilling small holes of shallow depth. He is unable to cope with very strong concrete. After working with a gentle drill, it takes a lot of time to remove debris from the hole, the drill itself does very poorly with this task. The gentle drills have an advantage - they are stronger and more reliable than, for example, spiral-shaped ones.
Purchase Features
To choose the right drill bits for concrete, the price of which can vary significantly, you must first determine for what purpose it is needed. If you intend to constantly work with thick strong walls, it is better to buy a screw or SDS-drill. For periodic drilling of small holes for domestic use, a gentle drill will be sufficient. The cost of the drill varies greatly depending on their quality and ability to cope with strong and thick walls. Simple gentle drills can be purchased for 20-30 rubles, the price of reinforced SDS models reaches 200 rubles and higher.
In any case, a high-quality tool can be bought exclusively in a specialized store. Moreover, such a drill can not be too cheap. Having saved a little and bought a cheap low-quality fake of a famous brand, you can significantly complicate your work.
