Abstract:

Machine tools for cutting metal are provided having a polygon cross-sectional geometry self-centering, high torque transmitting, rotatable tool support bar that is movable along the longitudinal axis of the bar. The tool support bar is coupled to the drive mechanism for rotating the bar, at a point proximate to the exit of the bar from the machine, by a coupling having a slidably mating polygon geometry opening through which the bar passes. In an embodiment of the invention there is further provided means for releasably locking the tool support bar in a predetermined extended position.
