    摘要: A pocket restitution assembly comprises a pocket formed in a surface that includes a central axis, an anchor seated in the pocket and aligned with the central axis, a tool attachment comprising an end for connection to the anchor, and a hollow bit slidably and rotatably sitting on the tool attachment. The hollow bit may fit within the pocket. Weld material may be deposited within the pocket to form an interior of the pocket. The weld material may be shaped by the hollow bit to accept a cutting element.

    摘要: 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.
