Abstract

In one aspect of the invention, a high impact resistant tool having a superhard 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.050 to.125 inch radius. The superhard material also has a.100 to.500 inch thickness from the apex to the non-planar interface.
