Cobalt drill bit,contain Co element in drill bit. the purpose of adding cobalt is to improve the high temperature resistance and anti-grinding characteristics of the drill bit, so as to achieve the goal of drilling. Generally there are two kinds of cobalt drill bit: normal cobalt(5%) and high cobalt(8%), cobalt drill bit with higher hardness than the general twist drill bit, but also fragile. It’s better for HRC40-55 hardness materials drilling.
Cobalt twist drill bit usage:
In practice, it is generally used to process stainless steel, copper and aluminum products. All of these products have high strength and therefore have poor plasticity. During the drilling of these materials, the chips are all attached to the drill bit. In order to solve this problem,cobalt drill bit, cluster drill be widely used. When a common drill bit encounters a high temperature and rapidly expands, the continuous application of torque by the drill shank causes the drill bit itself to break off, or the drill bit cannot be turned over.cobalt drill bit is a special twist drill bit be used to machining high strength and poor palsticity materials.
