The drill with the cutting edge is called a diamond drill. The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. It is one of the three new drilling technologies in the world in the 1980s. Field use proves that when drilling in soft-medium-hard formations, the diamond bit has the advantages of high speed, large footage, long life, stable work, fewer downhole accidents, and good well quality. Diamond drill bits are not only used for a long time, but also can be reused. The use effect of the returned diamond drill bit is similar to that of the factory diamond drill bit, which can save a lot of drilling costs.
