Abstract
A drill bit for drilling a borehole in an earthen formation includes a first blade having a cutter-supporting surface. The cutting profiles of cutting faces of primary cutter elements mounted to the cutter-supporting surface define an outermost cutting profile Po in rotated profile view. A stabilizing member may be included, having an end distal the cutter-supporting surface including a tip. The tip may be offset from the outermost cutting profile Po in rotated profile view.
