    摘要: In one aspect of the present invention, a high impact resistant tool has a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide segment. A stem formed in the base end of the carbide segment opposite the front end is press fit into a bore of a steel body. The steel body is rotationally fixed to a drum adapted to rotate about its axis.

    摘要: 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 0.050 to 0.125 inch radius. The superhard material also has a 0.100 to 0.500 inch thickness from the apex to the non-planar interface.

    摘要: In one aspect of the invention, a high impact resistant tool having a superhard bonded to a cemented metal carbide substrate at a no n-planar interface. The superhard material has a substantially pointed geometry with a sharp apex having 0.050 to 0.125 inch radius. The superhard material also has a 0.100 to 0.500 inch thickness from the apex to the non-planar interface. The diamond material comprises a 1 to 5 percent concentration of binding agents by weight. The tool further comprises a central axis which intersects the interface between the diamond material, substrate, and the radius of curvature.
