摘要： An earth-boring bit has a bit body, at least one cantilevered bearing shaft depending inwardly and downwardly from the bit body, and a cutter mounted for rotation on the bearing shaft. The cutter includes a plurality of teeth that are covered with a hardfacing layer. At least some of the teeth have a leading side that has a streamlined contour. The streamlined contour is generally conical in some of the embodiments. In others, the streamlined contour is defined by a corner between diverging inner and outer sections of the leading side.

摘要： 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.

摘要： A large hole earth boring bit with a clevis-type coupling for mounting the rolling cutters to the bit. The mounting apparatus includes a first member having two ends with aligned holes and a second member having its end inserted between the two ends. The end of the second member has an aperture that is spaced slightly out of alignment with the apertures in the first member, providing a generally elliptical passage. Bearing surfaces prevent them from coming into alignment. A pair of wedges are inserted into the elliptical passage and drawn together to exert a force in the direction toward alignment of the apertures. The force exerted is transmitted into the base, positively locking the two members together.

摘要： An earth boring bit having a cone rotatably secured to a cantilevered bearing shaft and a nozzle that discharges a jet stream of fluid having a high velocity core and a lower velocity skirt. The high velocity core is fully contained in a space bounded by the backside of the cone, bit leg, borehole wall and a radial plane tangent to the tips of the heel teeth and intermittently strikes the exposed ends of the erosion and wear resistant teeth when the cone rotates the teeth on the trailing side in and out of the jet stream. Less than half of the fluid in the lower velocity skirt strikes the surface of the cone, while the remainder continues on a path toward the wall and the borehole bottom. The centerline of the high velocity core is aimed no lower than the corner of the borehole. The jet stream is confined on more than about 75 percent of its periphery by either the cone, bit leg or the wall of the borehole, reducing undesirable recirculation and turbulence and opening a large return flow area unobstructed by a high velocity jet stream.

摘要： An earth-boring bit for attachment to a drill string has rotatable cones with rows of cutting elements. The cutting elements are arranged in generally circumferential rows on each of the cones and interference fit into apertures in the shell surface. The rows include a heel row of cutting elements on the heel surface of each of the cones, and an adjacent row of adjacent row cutting elements next to the heel row cutting elements. Each heel row cutting element has at least one counterpart adjacent row cutting element that is spaced no farther from it than any other adjacent row cutting element, defining a proximal pair. Each of the cutting elements in each of the proximal pairs has a grip ratio, which is the barrel length divided by the diameter. Some of the proximal pairs having cutting elements with higher grip ratios than other cutting elements. None of the proximal pairs has both cutting elements with higher grip ratios.

摘要： An earth-boring bit of the rolling cutter variety is provided with hard gage inserts that protrude from the gage surface of the cutter to engage the side of the borehole for holding gage. The gage insert has a substantially flat face with sharp cutting edges formed thereon and has cutting surfaces that define a negative rake angle with respect to the sidewall of the borehole that is being sheared by the gage insert. The cutting surfaces are comprised of multiple chamfers. The face, cutting edge, and cutting surfaces of the gage insert are formed of a super-hard and abrasion-resistant material such as polycrystalline diamond or cubic boron nitride. The body of the insert is formed of a hard, fracture-tough material such as cemented tungsten carbide. The improved gage inserts provide an actively cutting gage surface that engages the sidewall of the borehole to promote shearing removal of the sidewall material. Such an improved gage insert provides an earth-boring bit with improved gage-holding ability, and improved steerability in directional drilling operations.
