This specialized socket wrench/hammer does one thing: it turns the nut at the top of a standard Morse taper milling machine spindle. The brass hammer side is to gently tap the top of the threaded rod after loosening the nut. This knocks the collet or bit holder out the bottom of the spindle. OK I guess it does two things.
