    摘要： Cutter elements for use in rolling cones rock bits are disclosed having a crown that includes multiple, spaced-apart cusps for enhancing formation removal by creating overlapping Hertzian contact zones. The cusps may be partially dome-shaped, berm shaped or otherwise. The cutter elements provide multiple cutting edges for engaging the formation and may have differing radii and extension length as suitable for particular applications.

    摘要： A cutting element is disclosed having multiple cutting extensions extending from the base portion and separated by valleys. The cutting extensions of the cutting element include both crested and rounded shapes. The cutting extensions may differ in extension height, shape, extension angle, cant angle, and crest angle in other characteristics such as in material properties such as wear resistance, hardness and fracture toughness. The cutting elements have particular, but not exclusive, application in the nose portion of the cone cutters of a rolling cone bit.

    摘要： A cutter element for use in a drill bit, comprising a substrate and a plurality of layers thereon. The substrate comprises a grip portion and an extending portion. The layers are applied to the extending portion such that at least one of the layers is harder than at least one of the layers above it. The layers can include one or more layers of polycrystalline diamond and can include a layer in which the composition of the material changes with distance from the substrate.
