    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 paste compound disposed within the voids formed about the damaged substrate. The damaged substrate and the paste 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, applying a paste compound within the at least one void, melting the paste compound via induction heating, bonding the paste compound to the substrate and forming a processed PDC cutter, and grinding at least a portion of the paste compound from the processed PDC cutter to form the repaired cutter.

    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.

    摘要： A downhole tool and method for manufacturing such downhole tool. The downhole tool includes a bit body having a blank and a matrix bonded to and surrounding the blank, a shank having a threaded connection at one end, and a butt joint formed within a gap formed between the blank and the shank and coupling the blank to the shank. The blank includes a first planar surface while the shank includes a second planar surface opposite the one end. The butt joint is formed between the first and second planar surfaces when positioned adjacent to one another, wherein the first planar surface is positioned external to the matrix.
