Abstract
A superabrasive compact (e.g., a polycrystalline diamond compact) is disclosed, which includes a substrate pre-coated with at least one braze layer and an in-process drill bit assembly including at least one of such superabrasive compacts. Pre-coating the substrate with at least one braze layer and dimensioning the pre-coated substrate to fit within the tolerances of a conventionally-sized cutter recess of a drill bit body enables a drill bit manufacture to easily and rapidly braze the disclosed superabrasive compacts into the conventionally-sized cutter recess without substantially decreasing the superabrasive volume of the superabrasive compact.
