PDC is a kind of bit which uses PDC as cutting edge. It is an integrated bit, which has the advantages of high wear resistance, high strength and impact resistance. The bit is one of the three new drilling technologies in the modern world because of its simple structure without movable parts on the body. A large number of applications have proved that diamond composite bit has the advantages of high speed, more footage, and long service life, stable operation, less drilling accidents and good borehole quality when it is used in soft medium hard formation. Compared against conventional diamond bit, it has the advantages of low cost and wide range of application. Flat type Diamond PDC drill bits it is widely used in well drilling, geological coring exploration, mineral exploration and other industries.
