ABSTRACT:
A rotary tool assemblage includes an axially movable rotary tool and apparatus for holding a workpiece for engagement by the tool. A guide bushing is rotatably supported and interposed between the tool and the workpiece to guide and pilot the tool. The guide bushing and tool are rotationally interlocked to preclude relative rotational movement therebetween.
