摘要:
A high impact resistant tool includes a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The superhard material has a substantially pointed geometry with a sharp apex having a radius of curvature of 0.050 to 0.125 inches. The superhard material also has a thickness of 0.100 to 0.500 inches from the apex to a central region of the cemented metal carbide substrate. The diamond material comprises a 1 to 5 percent concentration of binding agents by weight.
