Abstract
A reinforcing metal blank may be used to form metal matrix composite (MMC) drill bits. For example, an MMC drill bit may include a shank attached to a reinforcing metal blank that extends into a bit body comprising a metal matrix composite, wherein the reinforcing metal blank comprises reinforcing structures that are positioned along at least a portion of an inner surface and/or at least a portion of an outer surface of the reinforcing metal blank and extend into the metal matrix composite; and a plurality of cutting elements coupled to an exterior portion of the bit body.
