    摘要： In one aspect of the present invention, a drill bit has a jack element that is substantially coaxial with an axis of rotation of the drill bit and the jack element has an asymmetrical distal end that extends beyond a working face of the drill bit. A turbine is located within a bore formed in the drill bit and a flow valve is actuated by the turbine. The flow valve is adapted to route a drilling fluid in the bore into a porting mechanism adapted to extend the jack element farther beyond the working surface of the drill bit. The turbine is also adapted to rotate the jack element at variable speeds.

    摘要： In one aspect of the invention, a pick comprises a front portion with an impact tip brazed to a carbide bolster. The carbide bolster comprises a cavity which is formed in the bolster's base end and which is adapted to interlock with a rear portion of the pick. The rear portion is adapted to be retained within a bore of a holder that is attached to a driving mechanism. The rear portion comprises a locking mechanism adapted to lock its first end within the cavity. The locking mechanism comprises a radially extending catch that is formed in the first end of the rear portion.
