ABSTRACT:
A tool has a shank extending axially in one direction from a material-removing formation and engageable in the chuck of a handle-held electric drill, and has a shaft extending axially in the opposite direction. A handle is rotatable on but axially fixed on this shaft and a guide ring can be secured at any position along it. This guide ring can therefore ride along a guide and determine the exact axial position of the material-removing formation relative to the workpiece edge of a guide securable to the workpiece.
