摘要: In one aspect of the invention, 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 thickness from the apex to a central region of the cemented metal carbide substrate.

摘要: In one aspect of the invention, a pick comprises a carbide bolster disposed intermediate an impact tip and a shank assembly. The impact tip comprises a superhard material bonded to a carbide substrate, and the tip is bonded to the bolster opposing a base of the bolster. The shank assembly comprises a central axis, a first end that protrudes into a cavity formed in the base of the bolster, and also an inducible attachment mechanism disposed proximate the first end. The inducible attachment mechanism is adapted to attach the shank assembly to the carbide bolster and restrict movement of the shank assembly with respect to the carbide bolster. The attachment mechanism may restrict movement of the shank assembly in a direction parallel to the central axis.

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.

摘要: In one aspect of the present invention, a tool assembly comprises a rotary portion and a stationary portion. The rotary portion comprises a bolster bonded to a diamond symmetric, substantially conically shaped tip. The stationary portion comprises a block mounted to a driving mechanism. A compressible element is disposed intermediate and in mechanical contact with both the rotary and stationary portions. The compressible element is compressed sufficiently to restrict free rotation during a degradation operation.
