It's no secret that it is unlikely to make a hole in reinforced concrete with an ordinary drill. If you try to do this, the product will slide on the concrete surface and become unusable.
In general, concrete is the most difficult and unyielding material to process. To work with it, special Pobedit drills are used, on which carbide plates are welded.
The material for the manufacture of products is an alloy of cob alt and tungsten carbide. And the hardware received the name "victory drills" from the word "victory". Because the drills created in the last century were designed to defeat concrete or other material.
Pobedit drills require special operating conditions. In their device, a carbide plate is attached to the body by soldering. During operation, the active part of the tool is subject to strong heating, while the strength of the soldering decreases, which leads to the likelihood of the plate breaking.
To prevent this from happening, Pobedite drills must be cooled periodically. Products of the latest generations receive a plate using laser welding. This makes it possible to withstand heating up to 1200C degrees, and drilling can be carried out at a higher speed.
New developments can significantly change the structure of the carbide insert. Today, along with tungsten carbide, nitrides and carbides of titanium, boron, and silicon are used. However, even such combinations are difficult to drill concrete. Significantly accelerate this process allows the use of reciprocating (shock) motion simultaneously with rotational. This cracks the concrete at the point of impact, and drilling gives a better result.
For concrete processing, pobedit drills must be used in special drills equipped with an impact device. This will allow you to achieve optimal drilling and punching.
To speed up the process and extend the life of the product, every 15 seconds of work, take the drill out of the hole, insert the same product into the hole that has served its purpose, and perform a couple of blows on it with a hammer.
To achieve success allows asymmetric sharpening of the drill. This allows you to speed up the process of drilling concrete. It turns out that even a strong, victorious drill is not suitable for processing steel, and sometimes even soft material. Therefore, colliding with fittings, products can be damaged. Modern technological hardware are resistant to overheating and in the process of drillingable to overcome any obstacle. Otherwise, the victorious product should be replaced with a step drill for working with metal.
To increase the speed of work, hard alloy inserts are used, equipped with teeth along the cutting edge. Thanks to special sharpening, such products can process any material (concrete, granite, steel, glass and even wood). Sometimes in the process of work they use sets of hardware, which includes a drill for tile, metal, wood, etc.
