International Classification:
E21B 10/36
US Classification:
175432, 175425
Abstract:
In one aspect of the invention, a drill bit comprises a steel body disposed intermediate a threaded end and a working face. The steel body comprises a plurality of steel blades disposed along an outer diameter of the body and extending radially away from an axis of rotation of the bit.

International Classification:
E21B 10/04, E21B 10/26
US Classification:
175404, 175385
Abstract:
A drill bit has a bit body intermediate a working face and a shank end adapted for connection to a downhole drill string. The working face has at least three fixed blades converging towards a center of the working face and diverging towards a gauge of the bit, at least one blade having a cone region adjacent the center of the working face. The cone region increases in height away from the center of the working face and towards a nose portion of the at least one blade. An opening is formed in the working face at the center of the bit along an axis of the drill bit's rotation, the opening leading into a chamber with at least one wall. An indenting member is disposed within and extends from the opening, is substantially coaxial with the axis of rotation, and is fixed to the wall of the chamber.

International Classification:
E21B 10/26, E21B 10/40
US Classification:
175389, 175415
Abstract:
A drill bit assembly comprises a bit body intermediate a shank and a working face. The shank is adapted for connection to a drill string. The drill string comprising a fluid passage at least partially disposed within the body. A hammer assembly is movably disposed within the fluid passage along it central axis, the hammer assembly comprises a proximal end stabilized by a centralized upper bearing and a distal end stabilized by centralized a lower bearing. The distal end protrudes out of the working face and the hammer assembly comprises a carrier between the upper and lower bearings. Wherein, under normal drilling operations the carrier is adapted to resist a fluid pressure within the fluid passageway such that the fluid pressure will further extend the distal end of the hammer assembly from the working face by pushing on the carrier.
