—PRODUCT BRIEF—


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, 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.

PDC drill bit is a kind of new superhard material that is synthesized by carbide alloy and synthetic diamond polycrystal under high temperature and pressure. Compared with the traditional carbide alloy bit, Its service life is 10 to 30 times that of the traditional carbide bit.PDC bit's compound slice cutting structure just makes use of the mechanical property of rock and uses an efficient shearing method to break rock, so as to achieve the purpose of fast drilling.
