Winning Drills: Features and Applications

It is not a secret for anyone 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 intractable material to handle. To work with it, special poizdovye drills are used, on which carbide plates are welded.

Material for the manufacture of products standscobalt and tungsten carbide alloy. And the name "pobedit drills" hardware received from the word "victory". Since the drills created in the last century, were designed to defeat concrete or other material.

Pocket drills require special conditionsoperation. In their device, a carbide plate is attached to the body by soldering. In the process, the active part of the tool is subjected to strong heating, and the soldering strength decreases, which leads to the probability of plate separation.

To avoid this, pobedit drillsmust be periodically cooled. Products of the latest generations receive a plate using laser welding. This makes it possible to withstand heating up to 1200 ° C, and drilling can be carried out at a higher speed.

New developments can significantly changecarbide plate structure. 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 use of reciprocating (shock) movement simultaneously with the rotational. Due to this, the concrete at the point of impact cracks, and drilling gives the best result.

For the processing of concrete pobedit drills must be used in special drills equipped with a percussion device. This will allow to achieve the optimal mode of drilling and punching holes.

To speed up the process and extend service lifeproducts should be every 15 seconds of work to get the drill from the hole, insert into the hole the same product that has served, and perform a couple of blows on it with a hammer.

Asymmetric sharpening allows successdrill. This allows you to reproach the process of drilling concrete. It turns out that even the sturdy pobedit drill is not suitable for steel processing, and sometimes even soft material. Therefore, when faced with fittings, products can be damaged. Modern technological hardware has resistance to overheating and in the process of drilling can overcome any obstacles. In another case, you should replace the item with a step drill for working with metal.

To increase the speed of work using platesfrom hard alloys, equipped with a cutting edge teeth. Thanks to a 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.
