ABSTRACT:
A turret lathe box cutting-tool adaptable for interchangeable right hand and left handed cutting of a rotating workpiece, including mechanism for synchronized movement of the cutting blade and of the piece-support rollers to and from predetermined-set positions before initiating cutting and subsequent to cutting but before withdrawing of the workpiece such that pressure of the blade and of the supporting rollers is relieved by withdrawal from the predetermined-set positions prior to the withdrawal of the cut workpiece thereby substantially eliminating any possibility of scarring of the cut workpiece before the moving axially of the blade and rollers away from the cut workpiece.
