More Information
Summary:In accordance with embodiments of the present disclosure, systems and methods for manufacturing a macroscopically reinforced metal-matrix composite (MMC) fixed-cutter bit are provided. The reinforced drill bit may include a bit body constructed from an infiltrated MMC material and featuring several blade portions extending radially outward and downward from a shank of the drill bit. These blade portions are designed for contacting a subterranean formation. The drill bit also includes the shank, which is coupled to an end of the bit body opposite the blade portions, to connect the bit body to an upstream component of a drill string. The drill bit further includes a number of macroscopic bit reinforcements that are at least partially enclosed within the bit body. These bit reinforcements are each disposed in and aligned substantially with a corresponding blade portion of the bit body.
