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： 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： Disclosed are cutter elements for a drill bits having particular, but not exclusive, application on the nose portion of the cone cutters of a rolling cone bit. The cutter elements include a base, a cutting portion, and a plurality of cutting lobes extending radially from the cutting portion. Each lobe includes a forward-facing cutting face and trailing portion having a trailing surface that intersects the cutting face in a nonlinear cutting edge. The trailing surface is non-planar and recedes away from the cutting edge. In certain embodiments, the trailing surface is a partial dome shaped surface. The trailing portion provides strength and buttresses the cutting edge.

摘要： Drill bits comprise a plurality of steel cutting teeth each having a crest positioned at a tip portion of each tooth, a first flank surface extending from the crest to the cone, a second flank surface opposite the first flank surface and extending from the crest to the cone, and edge surfaces extending from the crest to the cone and interposed between the first and second flank surfaces. Each cutting tooth includes corners that extend from the crest to the cone that are defined by the interface between the first and second flank surfaces and the edge surfaces. A wear resistant surface is positioned on selective tooth surfaces comprising at least the crest and a portion of one or more of the corners. The wear surface is not disposed on at least a surface portion of one of the first and second flank surfaces and the edge surfaces.

The trailing portion provides strength and buttresses the cutting edge. A drill bit employing such cutter elements in the nose region of its rolling cones, either as a single element or in a circumferential row of such cutters, will aggressively attack the core regions of the borehole bottom.
