    摘要： A novel form of drill bit is disclosed. The bit (30) comprises a bit body having a leading face (32) and gauge surface (44, 46). Cutting inserts (32, 34, 36) are set into the bit body, each cutting insert being in the form of a segment of a composite PCD (polycrystalline diamond) or PCBN (polycrystalline cubic boron nitride) composite. Thus each insert has a PCD or PCBN compact (40) carried by a carbide backing (42). The PCD or PCBN compact of each insert is exposed at the leading face or at the gauge surface to perform an axial cutting or gauge maintenance function during drilling.

    摘要： A chain saw link or tooth is disclosed. The link or tooth (100) can be connected pivotally to other similar chain saw links to form the chain of a chain saw. The chain saw link has a link body (101) and one or more cutting inserts (106) fastened releasably to the link body. Each cutting insert is provided by a segment of a composite PCD or PCBN compact (10) and has a PCD (polycrystalline diamond) or PCBN (polycrystalline cubic boron nitride) compact carried by a carbide backing. When installed, the PCD or PCBN compact of the insert is exposed in a position to perform a cutting action in use.
