SUPERABRASIVE CUTTERS FOR EARTH BORING BITS WITH MULTIPLE RAISED CUTTING SURFACES AND A DRILL BIT COMPRISING SUCH CUTTERS

OF THE DISCLOSUREA cutter (1, 12, 23, 33, 42, 48, 58) for a drill bit includes: a substrate (3, 60) for mounting the cutter (1, 12, 23, 33, 42, 48, 58) to the drill bit (15); and a cutting table (2, 24). The cutting table: is made from a superhard material, is mounted to the substrate, has an interface (4, 45) with the substrate at a lower end thereof, and has a working face (5) at an upper end thereof. The working face has a protruding center section (7) and a plurality of protruding ribs (8a-c, 28a-c, 38a-c, 46a-c, 54a-c, 64a-c). Each rib extends radially outward from the center section to a side of the cutting table. Each rib has a triangular profile formed by a pair of inclined side surfaces (10s, 30s, 40s) and a ridge (10r, 30r, 40r) connecting opposing ends of the side surfaces. The working face further has a plurality of recessed bases (6a-c, 26a-c, 36a-c, 52a-c, 62ac) located between adjacent ribs and each extending inward from the side.Further, a drill bit (15) comprising the cutter (1, 12, 23, 33, 42, 48, 58).
