 FEATURES:
 Matrix drill bit with five blades of medium long parabola crown profile and with medium cutter density.
 Non-planar interfaced diamond/carbide cutters absorb effectively high stress and minimize cutter fracturing and wearing.
 Asymmetrical blades arrangement and special load-balanced cutter arrangement design improves bit stability and therefore higher ROP

PDC ( polycrystalline diamond compact) cutters both new and used on sale

The polycrystalline diamond compact (PDC) is composed of a polycrystalline Diamond layer and a tungsten carbide substrate. The polycrystalline diamond layer possesses extremely high hardness and abrasion resistance, whereas the Tungsten Carbide substrate would greatly improve the toughness and weldability of  the whole compact.


FEATURES:
Enhanced thermal abrasion resistance
Superior impact resistance / toughness






BENEFITS:
Significantly improved durability
Drills further, faster
Stays sharper, longer to lower drilling costs
