ABSTRACT:
An abrasive material has a contoured surface defining peaks and valleys, and side walls connecting the two. The peaks, side walls and valleys are covered with diamonds or other hard particles for effecting the grinding. In the beginning, the hard particles support one another laterally to prevent premature removal of particles, and the valleys provide for fluid flow for debris removal, cooling and protection of the retaining matrix. Later, the particles on the side walls, and eventually those in the valleys, become active in grinding, so that tool life is extended.
