    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.

    摘要: A composite heat spreader is disclosed in one embodiment of the invention as including an input interface to conduct heat from a heat source, such as an integrated circuit, and an output interface to transfer heat to a heat sink. A support material having a first thickness is provided between the input interface and the output interface. One or more diamond monocrystals are embedded in the support material and have a second thickness which is at least 20% of the first thickness. In some embodiments, the diamond monocrystals extend from the input interface to the output interface. These one or more diamond monocrystals may be either rough or finished diamonds.
