Claims

[Claims for Utility Model Registration] (1) A cutter shaft whose tip, which is a cutting part, protrudes from the end of the chamfering tool body and is driven by a drive motor built into the chamfering tool body; The chamfering tool is equipped with a chamfer positioning guide mechanism that is attached near the tip of the cutter shaft of the tool body and abuts against the workpiece to define the chamfer area, the chamfer positioning guide mechanism The guide mechanism includes a first reference plate that extends across the direction in which the cutter shaft extends and has an opening for protruding the tip of the cutter shaft toward the front; tongue-shaped first base plates that are connected with a step and extend across the top of the tip of the cutter shaft, the tip R portion of which extends to a position separated by a predetermined distance from the periphery of the opening of the first reference plate; 2. A chamfering tool comprising: 2 reference plates. (2) Practical use characterized in that the opening is a circular opening formed in the center of a disc-shaped first reference plate, and the second reference plate protrudes from the inner peripheral edge of this opening. A chamfering tool according to claim 1 of the patent registration claim.
