    摘要： An earth boring bit having a body provided with a shank having a tubular bore and a head along the opposite end of said body having flow passages communicating with the bore, the head having face portions including a center end face portion, a nose portion, a shoulder portion, and a gage portion along the maximum diameter of the bit, and cutting elements mounted over said face portions having cutting faces oriented in the direction of rotation of the drill bit, the areas of the cutting faces of the cutting elements ranging from a maximum at the center face portion to a minimum at the gage portion of the bit. The cutters may be individually mounted, mounted in groups, arranged in random patterns, and arranged in a variety of other patterns, including radial longitudinal rows circumferentially spaced around the bit face.

    摘要： A repaired polycrystalline diamond cutter and method for fabricating the same. The cutter includes a damaged substrate that includes at least one void therein, a polycrystalline diamond table coupled to the damaged substrate, and a build-up compound disposed within the voids formed about the damaged substrate. The damaged substrate and the build-up compound collectively form a full circumference. The method includes obtaining a damaged cutter that includes a polycrystalline diamond table coupled to a damaged substrate having at least one void formed therein, bonding a build-up compound within the at least one void and forming a processed PDC cutter, and removing a portion of the build-up compound from the processed PDC cutter and forming the repaired cutter.
