摘要： In one aspect of the invention, a superhard insert has a carbide substrate bonded to ceramic layer at an interface. The substrate has a generally frusto-conical end at the interface with a tapered portion leading to a flat portion. The central section of the ceramic layer may have a first thickness immediately over the flat portion of the substrate. The peripheral section of the ceramic layer has a second thickness being less than the first thickness covering the tapered portion of the substrate. The ceramic layer may be formed using HPHT technology.

摘要： In one aspect of the invention, a tool has a working portion with at least one impact tip brazed to a carbide extension. The carbide extension has a cavity formed in a base end and is adapted to interlock with a shank assembly of the cutting element assembly. The shank assembly has a locking mechanism adapted to interlock a first end of the shank assembly within the cavity. The locking mechanism has a radially extending catch formed in the first end of the shank assembly. The shank assembly has an outer surface at a second end of the shank assembly adapted to be press-fitted within a recess of a driving mechanism. The outer surface of the shank assembly has a coefficient of thermal expansion of 110 percent or more than a coefficient of thermal expansion of a material of the driving mechanism.
