Beschreibung
Zusammenfassung:	Machine tools for cutting metal are provided having a polygon cross-sectional geometry self-centring, high torque transmitting, rotatable tool support bar (21) 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 (P) proximate to the exit of the bar from the machine, by a coupling (24) having a slidably mating polygon geometry opening (71) through which the bar passes. In an embodiment of the invention there is further provided means (81-91) for releasably locking the tool support bar (21) in a predetermined extended position.
