PDC (Polycrystalline Diamond Compact) Cutters
PDC cutters consist of PCD layer integrally sintered at ultrahigh pressure and high temperature to a cemented tungsten carbide backing. They have high hardness, wear(abrasion) resistance and impact resistance, are widely used for oil well drilling, geological drilling and mining, applied to soft to medium hard formations. And also could be used be on some grinding tools.
PDC cutters for oil well drill bit, GK series.
GK is a premium cutter, we adopt some new technology, greatly improve the impact resistance and thermal stability, increase the rate of penetration in highly demanding drilling applications effectively.

The PCD (Polycrystalline Diamond) layer has complete diamond-to-diamond bonding between the grains, has high strength, hardness and wear(abrasion) resistance. It provides a cutting structure for the rock formations that respond well to failure by shearing and wears by micro-chipping, so that the cutters continually provide new, shape cutting edges.

Select a new type of tungsten carbide as the backing, improves the toughness and the solderability.

The claw joint face between the PCD layer and the tungsten reduces the residual stress and increases the impact resistance of the PDC cutter.
