ABSTRACT:
A depth stop is provided that is selectively attachable to a cutting tool at an operator-selected location. The end of the depth stop that comes into contact with a work piece during operation is covered with a rotating cap. The cap prevents the work piece from being marred because the cap stops rotating when it comes into contact with the work piece while the cutting tool and the rest of the depth stop continue to rotate. The cap is rotatably mounted on the depth stop by a flange that engages a groove formed in the depth stop. An annular ring is provided between the cap and the end of the depth stop body to facilitate the rotatability of the cap with respect to the body.
