Abstract
A boring bar in which a cutter element holder is adjustable around a transverse pivot axis, so that different cutting elements can be used to machine the hole surface during movement of the boring bar in opposite directions. The transverse pivot axis is defined by a torsional hinge that automatically returns the holder to a neutral position when the adjustment force is removed.
