PDC matrix bit is a kind of cutting bit that weld the diamond composite piece on the drill head body by brazing. PDC matrix bit is sintered with tungsten carbide powder, brazed on tungsten carbide body with man-made polycrystalline diamond composite sheet, and diameter retaining with natural diamond. The tungsten carbide body has high hardness and erosion resistance, so the service life of the body is long.

The hardness of PDC matrix bit is high and corrosive, so the PDC matrix bit has a long single life and high inlet, which is widely used in natural gas drilling and deep wells.
