Patent ID: 8051923

Claim:
A rotary drill bit operable to form a wellbore comprising: a bit body having one end operable for attachment to a drill string; a bit rotational axis extending through the bit body; a plurality of blades disposed on exterior portions of the bit body; at least one of the blades having a gage pad with an exterior surface operable to contact adjacent portions of a wellbore formed by the rotary drill bit; the exterior surface of the gage pad including: an uphole edge with a leading edge defined in part by a first radius extending from the bit rotational axis to the uphole edge and a trailing edge defined in part by a second radius extending from the bit rotational axis to the uphole edge, the first radius larger than the second radius as measured in a plane extending generally perpendicular to the bit rotational axis, the leading edge and the trailing edge extending downhole from the uphole edge; a generally curved surface extending from the leading edge toward the trailing edge of the gage pad; and a generally flat, noncurved surface extending from the trailing edge toward the leading edge of the gage pad, the generally flat, noncurved surface intersecting with the generally curved surface.
