Winch Drills: Features and Applications

It's not a secret that it is unlikely to make a hole in reinforced concrete with an ordinary drill. When trying to do this, the product will slide over the concrete surface and become unusable. In general, concrete is the most complex and intractable material for processing. To work with it, special winning drills are used, on which hard -alloy plates are welded .

The alloy for cobalt and tungsten carbide is a material for the manufacture of products . And the name "victorious drills" of hardware was obtained from the word "victory". Since the drills created in the last century were designed to defeat concrete or other material.

Winch drills require special operating conditions. In their arrangement, the 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 soldering decreases, which leads to the probability of tearing off the plate. To prevent this from happening, the winning drills need to be cooled periodically. The products of the latest generations are produced by laser welding. This makes it possible to withstand heating up to 1200 ° C, and also drilling can be carried out at a higher speed.

New developments make it possible to significantly change the structure of the carbide plate. Today, simultaneously with tungsten carbide, nitrides and carbides of titanium, boron, and silicon are used. However, such combinations are difficult to drill concrete. Significantly accelerate this process allows the application of reciprocating (shock) motion simultaneously with the rotational motion. Due to this, concrete at the point of impact is cracked, and drilling gives the best result.

For the treatment of concrete, the winning drills must be used in special drills equipped with a percussion device. This will achieve an optimal drilling and punching mode. To accelerate the process and extend the life of the product, after every 15 seconds of work, take the drill out of the hole, insert into the hole the same product that has served it, and carry out a pair of blows with a hammer.

Asymmetric sharpening of the drill allows to achieve success . This allows you to rebuke the process of drilling concrete. It turns out that even a strong winning drill is not suitable for processing steel, and sometimes even soft material. Therefore, when faced with fittings, products can be spoiled. Modern technological hardware has a resistance to overheating and can overcome any obstacles during drilling. In another case, it is necessary to replace the winning product with a stepped drill for working with metal.

To increase the speed of work use plates of hard alloys, equipped with a cutting edge teeth. Similar products can be treated with any sharpening material (concrete, granite, steel, glass and even wood). Sometimes in the process of working using a set of hardware, which includes a drill bit for tile, metal, wood, etc.
