ABSTRACT:
A spring actuated, pivoting cutting tool, which is used in conjunction with turning equipment and which at the termination of its cutting stroke automatically lifts the cutting edge off the finished surface to allow the tool to be withdrawn without leaving a return mark, is provided with a spring actuated, slidable shield which substantially covers any gap between the moving parts of the cutting tool, thus reducing the likelihood of chips or other debris from lodging between the moving parts of the tool and preventing its proper operation.
