    摘要： 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. At least one of the cutting elements has a generally cylindrical body formed of hard metal with a convex cutting end. A plurality of recesses extend longitudinally from the apex to the junction. The recesses are shallow grooves symmetrically spaced about the axis. A layer of super-hard material is formed on the cutting end of the body and overlays the recesses formed thereon.

    摘要： A cutter of an earth-boring bit 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 face, cutting edge, and cutting surface 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 are secured into sockets in the gage surface of the rolling cone cutter by interference fit. 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.

    摘要： A method for manufacturing an earth boring drill bit and bit produced thereby are shown. The bit has rotatable cutters with a plurality of milled teeth, each of the teeth having opposing flanks. A first tube hardfacing is applied to a selected one of the opposing flanks, the hardfacing comprising a metallic binder with wear-resistant particles dispersed throughout the binder. The other of the opposing flanks has a second tube hardfacing applied thereto. The particle size of the wear-resistant particles differs between the first and second tube hardfacings so that the resulting difference in abrasion resistance of the tooth flanks produces a self-sharpening effect as the tooth wears.

    摘要： Earth-boring tools include a body, one or more blades projecting outwardly from the body, and cutting elements carried by the blade. The cutting elements include at least one shearing cutting element and at least one gouging cutting element. Methods of forming an earth-boring tool include mounting a shearing cutting element comprising an at least substantially planar cutting face to a body of an earth-boring tool, and mounting a gouging cutting element comprising a non-planar cutting face to the body of the earth-boring tool. The gouging cutting element may be positioned on the body of the earth-boring tool such that the gouging cutting element will gouge formation material within a kerf cut in the formation material by the shearing cutting element, or between kerfs cut in the formation material by a plurality of shearing cutting elements.

    摘要： Polycrystalline compacts include a hard polycrystalline material comprising first and second regions. The first region comprises a first plurality of grains of hard material having a first average grain size, and a second plurality of grains of hard material having a second average grain size smaller than the first average grain size. The first region comprises catalyst material disposed in interstitial spaces between inter-bonded grains of hard material. Such interstitial spaces between grains of the hard material in the second region are at least substantially free of catalyst material. In some embodiments, the first region comprises a plurality of nanograins of the hard material. Cutting elements and earth-boring tools include such polycrystalline compacts. Methods of forming such polycrystalline compacts include removing catalyst material from interstitial spaces within a second region of a polycrystalline compact without entirely removing catalyst material from interstitial spaces within a first region of the compact.

    摘要： Cutting elements for use in earth-boring applications include a substrate, a transition layer, and a working layer. The transition layer and the working layer comprise a continuous matrix phase and a discontinuous diamond phase dispersed throughout the matrix phase. The concentration of diamond in the working layer is higher than in the transition layer. Earth-boring tools include at least one such cutting element. Methods of making cutting elements and earth-boring tools include mixing diamond crystals with matrix particles to form a mixture. The mixture is formulated in such a manner as cause the diamond crystals to comprise about 50% or more by volume of the solid matter in the mixture. The mixture is sintered to form a working layer of a cutting element that is at least substantially free of polycrystalline diamond material and that includes the diamond crystals dispersed within a continuous matrix phase formed from the matrix particles.
