The chuck (100) may include a body (130) having a center axis (50) and a plurality of clamping jaws (101) configured to clamp onto a working bit. The clamping jaws (101) may be configured to angularly translate relative to the center axis towards or away from a clamping jaw point of convergence (154) to close or open a working bit opening defined by the clamping jaws (101). The clamping jaw point of convergence (154) may be on the center axis. The chuck (100) may also include a plurality of bit alignment jaws (150). The bit alignment jaws (150) may be configured to maintain the working bit within the working bit opening by being configured translate towards or away from a bit alignment jaw point of convergence (153) that is on the center axis (50) and disposed rearward of the clamping jaw point of convergence (154).
