In one aspect of the invention, a drill bit assembly has a body portion intermediate a shank portion and a working portion, the working portion having at least one cutting element. The working portion also has an opening to an axial chamber disposed in the body portion of the assembly. The drill bit assembly also has an axial shaft rotationally isolated from the body portion, the shaft being at least partially disposed within the chamber, and partially protruding form the working portion. The shaft is also in communication with an energy adapter disposed within the drill but assembly and is adapted to use relative motion between the body portion and the shaft to provide power to at least one downhole device.
