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.
