    摘要: In one aspect of the invention, an attack tool has a wear-resistant base suitable for attachment to a driving mechanism. A first end of a generally frustoconical first cemented metal carbide segment bonded to the base. A second metal carbide segment is bonded to a second end of the first carbide segment at an interface opposite the base. The first end has a cross sectional thickness of about 0.250 to 0.750 inches and the second end has a cross sectional thickness of about 1 to 1.50 inches. The first cemented metal carbide segment also has a volume of 0.250 cubic inches to 0.600 cubic inches.

    摘要: In one aspect of the invention, a tool has a wear-resistant base suitable for attachment to a driving mechanism and also a hard tip attached to an interfacial surface of the base. The tip has a first cemented metal carbide segment bonded to a superhard material at a non-planar interface. The tip has a height between 4 and 10 mm and also has a curved working surface opposite the interfacial surface. A volume of the superhard material is about 75% to 150% of a volume of the first cemented metal carbide segment.
