Cutting element apparatuses, drill bits including same, methods of cutting, and methods of rotating a cutting element

Abstract

A rotary drill bit for drilling a subterranean formation may comprise a bit body, a cutting element coupled to the bit body, and a torque-generating assembly configured to apply torque, either continuously or periodically, to the cutting element. The torque-generating assembly may be powered by the rotary motion of the rotary drill bit or may be hydraulically or electrically powered. The cutting element may comprise a substrate, a table of superabrasive material disposed on an end of the substrate, and at least one impelling feature formed along the exterior surface of the substrate. In addition, a method of rotating a cutting element coupled to a drill bit for drilling a subterranean formation may comprise providing a cutting element comprising a table bonded to a substrate, coupling the substrate of the cutting element to a drill bit body, and applying torque to the substrate of the cutting element.
