Abstract:
A drill bit assembly includes a drill bit body, an insulating layer disposed on an end of the drill bit body and that defines a drill bit face and two electrodes formed such that they both extend from the drill bit face. The two electrodes form a spiral on the drill bit face and are equidistant from each other at all locations of the drill bit face.
