PDC means Poly-crystalline diamond compact, it is made by tungsten carbide substrate and diamond powder under high temperature and high pressure. PDC (Poly-crystalline diamond compact) is an important material to manufacturing PDC drill bits in water well drilling and oil and gas drilling etc.

PDC bits have 2 types: Steel body PDC bits and matrix body PDC bits. Both of them have their own advantage, but they also have difference. It is up to the application and rock formation.

Steel body bit adopts steel as the body material. Steel is high impact toughness but is is relatively soft so it will be abrasion and erosion quickly. But its drilling speed in sot rocks is quickly. Matrix body pdc bit adopt tungsten carbide as the body material.Tungsten carbide is a metal material which is made of refractory metal carbides and binder by powder metallurgy. Tungsten carbide is very hard and wear-resistant that makes the drill bit have a long service life.
