ABSTRACT:
A tool for use with a tool holder has a body to which at least one blade such as a circular saw blade or milling cutter is clamped to prevent the blade from turning when a selected tooth is brought into cutting or grooving contact with a rotating work piece, the body of the tool has first and second parallel clamping surfaces through which a diametric slot opens. A first clamping member has a hub on which a blade is rotatably mounted and which fits the slot and is held thereby against turning. The two clamping members are connected by a threaded member by which the clamping members are drawn towards each other to clamp the blade against the first clamping surface. A member threaded radially through the body extends into the slot and is operable to move the hub radially with respect to the center thereof enabling positions of a tooth relative to the work piece to be precisely established. When more than one blade is mounted on the hub, the blades are held apart by a spacer.
