Core bit

PDC (Polycrystalline Diamond Cutters) are set on the crown giving a very long working life, very fast penetration and high percentage core recovery in soft to hard rock formations.

The surface of the disc-shaped cutting element consists of very fine synthetic diamond particles sintered together by high pressure and high temperature. On top of this diamond layer is a tungsten carbide stud which is brazed directly into the bit matrix. These cutters can take accommodate the very large compressive and shear loads generated during drilling.
