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. The diamond material comprises a 1 to 5 percent concentration of binding agents by weight.

The superhard material has a substantially pointed geometry with a sharp apex having 0.050 to 0.125 inch radius measured from a direction substantially perpendicular to a central axis of the tool. 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.

摘要: A high impact resistant pick in a holder having a super hard 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 bolster. A bore is formed in a base end of the carbide bolster generally opposed to the front end. A steel shank being fitted into the bore of the bolster at a bolster end of the shank, and a portion of the shank is disposed within a bore of the holder at a holder end of the shank.

摘要: In one aspect of the invention, a degradation pick comprises a bolster disposed intermediate a shank and an impact tip. The shank comprises an outer diameter and first and second ends. The shank is coupled to the bolster through the first end and the second end is adapted for insertion into a central bore of a holder attached to a driving mechanism. The shank comprises a hollow portion disposed within the outer diameter and between the first and second ends. The hollow portion may comprise an opening that is disposed in the second end. In some embodiments the hollow portion may comprise a length that is at least as great as the outer diameter.
