Mining | A. A small plate or slug of tungsten carbide alloy mounted in the crown or shank of a bit or in grooves on the outside surface of a reaming shell to provide wear-resistant or rock-cutting surfaces or edges. The term is sometimes incorrectly applied to diamond-set plates of tungsten carbide alloy inset as reaming surfaces in reaming shells b. In mining, a slug composed of tungsten carbide alloy shaped and mounted in the bit face so that the slug acts as the cutting edge of the bit c. Hemispherical-ended cylinders of sintered carbide are inserted in place of the usual teeth to give 10 to 15 times the total footage and 2 to 3 times the cutting rate. However, hard rocks are drilled more economicallyby diamond boring. (references) |
