  • Patent number: 5755297
    Abstract: A rotary cone drill bit for forming a borehole having a bit body with an upper end portion adapted for connection to a drill string. A number of support arms extend from the bit body. Each support arm has an exterior surface with a stabilizer pad formed as an integral part thereof. A number of cutter cone assemblies equal to the number of support arms are rotatably mounted on respective support arms and project generally downwardly and inwardly from each support arm. A ramp may also be formed on the exterior surface of the support arm as an integral part thereof. Both the stabilizer pad and the ramp preferably have surfaces inclined at an angle from a leading edge of the support arm toward a trailing edge of the support arm such that a fluid flow channel is formed therebetween to direct drilling fluids and cuttings to flow upward in the borehole.
