ABSTRACT:
Thermally stable abrasive compacts of hexagonal shape have been found to have excellent abrasive properties in the abrading of a medium to soft rock having an unconfined compressive strength of less than 240 MPa. Preferably the abrasive tool used is a surface set drill bit wherein some of the thermally stable abrasive compacts are so located around the working edge of the bit that a side thereof acts as a gauge stone for the working portion.
