The drill bit that makes the cutting edge is called a diamond bit. The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has the ability of high strength, high wear resistance and impact resistance. Field use has proved that when drilling in soft-to-medium-hard formations, the diamond bit has the advantages of high speed, long footage, long life, stable operation, few downhole accidents, and good wellbore quality. The diamond bit is not only used for a long time, but also can be reused. The diamond bit returned to the factory has the same effect as the factory diamond bit, which can save a lot of drilling costs.
