There are many types of diamond drills. According to the source of diamond, it can be divided into natural diamond drill bits and artificial diamond drill bits. According to the diamond inlay form, it can be divided into surface mounted drill bits and impregnated drill bits. The former consists of diamonds distributed on the surface of the drill bit, while the latter consists of many finer diamonds evenly distributed in the drill bit matrix. According to the purpose of drilling bits, they can be divided into core drilling bits and comprehensive drilling bits. People are also accustomed to naming according to processing and manufacturing methods, such as: hot pressed sintered diamond drill bits, low-temperature electroplated diamond drill bits, pressureless impregnated diamond drill bits, etc. Simply put, the process of working a diamond drill bit is the process of continuously breaking rocks with diamond. During the process of breaking rocks, it is necessary to apply a certain pressure and speed to the drill bit, so that the diamond can be pressed into the rock and continue to break the rock. During this process, the drill bit rubs against the rock, constantly generating heat and a large amount of small rock debris. It is necessary to provide circulating fluid to cool the drill bit and take away the rock debris, in order to improve the rock breaking efficiency of the drill bit.
