    摘要: In one aspect of the invention, a tool has a working portion with a 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.

    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: An impact tool for use with a driving mechanism, the impact tool including an impact tip formed from a super hard material and having an apex and an attachment end, with the attachment end being bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded in turn to the front end of a cemented metal carbide bolster. The carbide bolster is securable against an outer surface of a driving mechanism through a press fit.
