Abstract
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.
