  • Combination stop collar and cutting tool
    Patent number: 4039266
    Abstract: A longitudinal cutting tool is formed with at least one groove and a stop collar is received on the cutting tool. The stop collar has a stop surface, and yieldably resilient means in the form of a threaded screw passing through a slot in the collar, and rubberized buttons inserted into the collar are used to adjust the collar on the cutting tool, and to operatively connect it thereto so as not to damage its groove; the cutting depth of the tool is limited when the stop face engages with the stop surface.
