摘要

Workpiece turning assembly comprises at least two turning bits mounted in a holder for simultaneous engagement of the workpiece. Preferably at least two turning bits are mounted adjacent and parallel to each other. The holding elements for the bits are preferably adjustable within the holder and spacers may be included between the bits. Safety devices which include an elastic element for frictionally retaining a bit and/or spacer in the holder are preferably included to enable the holder to be manipulated without the bits and spacers falling out.
