Abstract

A method of manufacturing a drill bit and several embodiments of a drill bit for drilling a well in an earth formation. In one embodiment, the drill bit comprises a diamond impregnated bit body with one or more thermally stable pins embedded therein. More specifically, the drill bit may include a diamond impregnated bit body having a plurality of blades, with one or more of the blades having a cone section, a nose section, a shoulder section, and a gage section; a plurality of diamond impregnated cutters extending from the blades; and one or more thermally stable polycrystalline diamond pins embedded within, and possibly extending from, at least some of the cutters. In some embodiments, each cutter includes an embedded pin. Alternatively, the pin or pins may be located in the cone, shoulder, nose, and/or gauge sections.
