  • Rock bit and cutter teeth geometries
    Patent number: 9328562
    Abstract: A rolling cone drill bit for cutting a borehole comprises a rolling cone cutter mounted on a bit body and adapted for rotation about a cone axis. Further, the bit comprises a tooth extending from the cone cutter. The tooth includes a base at the cone cutter and an elongate chisel crest distal the cone cutter. The crest extends along a crest median line between a first crest end and a second crest end and includes an elongate crest apex. The tooth also includes a first flanking surface extending from the base to the crest, and a second flanking surface extending from the base to the crest. The first flanking surface and the second flanking surface taper towards one another to form the chisel crest. Moreover, the tooth includes a first raised rib extending continuously along the first flanking surfaces and across the chisel crest to the second flanking surface.
