Abstract

An earth boring drill bit comprising a bit body having a bit profile including nose, shoulder, and gage sections; a plurality of fixed cutting elements secured to the body and defining a fixed cutter profile; and a roller cone rotatably secured to the body, the roller cone having a plurality of roller cone cutting elements defining a roller cutter profile, wherein the fixed cutter profile extends beyond the roller cutter profile in at least one of the sections and the roller cutter profile extends beyond the fixed cutter profile in at least one of the sections. The roller cutter profile may extend beyond the fixed cutter profile in the shoulder and gage sections, possibly with the fixed cutter profile extending beyond the roller cutter profile in the nose section and/or a cone section.
