A drill bit (10) comprises a bit body (112) having a bit axis (111) and a bit face (120). The bit (110) comprises a plurality of gauge pads (151-201) extending from the bit body (112), wherein each gauge pad (151-201) includes a radially outer gauge-facing surface (130). The gauge-facing surfaces (130) of the plurality of gauge pads (151-201) define a gauge pad circumference (134) that is centered relative to a gauge pad axis (211), the gauge pad axis (211) being parallel and offset from the bit axis (111). |
