Abstract

A rock cutter (10) for improving the drilling performance of drag-type bits includes a body portion (12) and a cutter element (14) having an outer surface shaped to create a plowing effect so as to direct rock chips away from the surface. The cutter element is preferably V-shaped and formed of a composite compact of diamond cubic boron nitride or wurtzite boron nitride. <IMAGE>
