  • Shirttails for reducing damaging effects of cuttings
    Patent number: 7350600
    Abstract: An earth-boring bit has a bit body that includes head sections, each having depending bit legs with a circumferentially extending outer surface, a leading side, and a trailing side. A bearing shaft depends inwardly from each of the bit legs for mounting a cutter. The bit includes a beveled surface formed at a junction of the leading side and the outer surface of each bit leg. The beveled surface is angled relative to a radial plane emenating from the axis of the bit. The angle of the beveled surface is at least 20 degrees, and extends to an inner surface of the bit leg. The bit can also have a layer of hardfacing on the leading, trailing and shirttail surfaces of the bit leg. A diversion finger of hardfacing extends circumferentially to direct cuttings.

  • Gage surface scraper
    Patent number: 7066286
    Abstract: A gage scraper cleans mud from the gage surface of a rotary cone of a drill bit. The bit has a body having at least one leg depending therefrom, a bearing pin secured to each leg, and a rotary cutting cone mounted to the bearing pin. The cone has a conical gage surface. The gage scraper mounts on the inside of each leg and protrudes from the leg toward the cone into close proximity with the gage surface.
