摘要: A drill bit has a body intermediate a shank and a working face and has an axis of rotation. The working face has at least one cutting element and the body has at least a portion of a jack assembly. The jack assembly has at least a portion of a shaft disposed within a cavity formed in the body of the drill bit, the shaft having a distal end extending from an opening of the cavity formed in the working face. The jack assembly also has an electric motor and/or generator.
