  • Earth-boring bit having shear-cutting heel elements
    Patent number: 5592995
    Abstract: An earth-boring bit has a bit body and at least one cantilevered bearing shaft depending inwardly and downwardly from the bit body. A cutter is mounted for rotation on the bearing shaft and includes a plurality of cutting elements arranged in generally circumferential rows including an outer or heel row of cutting elements. At least one of the cutting elements in the heel row has an outermost surface at least partially formed of super-hard material that defines a cutting edge for shearing engagement with the sidewall of the borehole as the cutters roll and slide over the bottom of the borehole during drilling operations.
