Abstract
Embodiments of the disclosure provide a drill bit including a drill bit body having a central axis. A first cutting edge is disposed on the drill bit body at a first radial distance from the central axis as measured within a plane normal to the central axis. And a second cutting edge is disposed on the drill bit body at a second radial distance from the central axis as measured from within the plane. The first radial distance is less than the second radial distance.
