    摘要: Earth-boring rotary drill bits include bit bodies comprising a composite material including a plurality of hard phase regions or particles dispersed throughout a titanium or titanium-based alloy matrix material. The bits further include a cutting structure disposed on a face of the bit body. In some embodiments, the bit bodies may include a plurality of regions having differing material compositions. For example, the bit bodies may include a first region comprising a plurality of hard phase regions or particles dispersed throughout a titanium or titanium-based alloy matrix material, and a second region comprising a titanium or a titanium-based alloy material. Methods for forming such drill bits include at least partially sintering a plurality of hard particles and a plurality of particles comprising titanium or a titanium-based alloy material to form a bit body comprising a particle-matrix composite material. A shank may be attached directly to the bit body.

    摘要: An earth boring drill bit comprising a milled cutter having rows of hardfacing guides on the cutter. Hardfacing is applied between adjacent hardfacing guides to form a hardfacing web that serves as a cutting element. The hardfacing web defines an interface between the hardfacing web and the hardfacing guide. The hardfacing web may extend past the crest of the hardfacing guides or end along the hardfacing guides flanks. Projecting hardfacing is provided on the interface to form trimmers.

    摘要: An earth boring bit has three cones, each cone being mounted for rotation about a cone axis while the bit rotates about a bit axis. An outer row and an adjacent row of cutting elements are integrally formed on each of the cones. Each of the cutting elements of the adjacent row on each of the cones has a crest extending perpendicular to a direction of rotation of the cone. Annular spaces are located between the outer row and the adjacent row on each of the cones. The annular space on one cone has a width that is less than the annular spaces on the other cones. The width of the narrowest annular space is greater than the width of the crests of the adjacent row.

    摘要: The harmful effects of tracking are reduced for a drill bit having roller cones with at least one of the outermost rows of active teeth containing one or more teeth having a height that does not extend to the height of at least one of the outermost rows on another roller cone on the bit. The crest on this tooth may have a length in a circumferential direction that is wider than an overall width of the tooth in the outer to inner direction. The invention may be used on any cutter row, not just the outermost row. The design may be used on a different roller cone or row, or more than one cutter row. The anti-tracking feature may be located between the leading and trailing edges of the tooth on one or more roller cones.
