Claims

[Scope of utility model registration request]

The tip, which is the cutting part, protrudes from the end of the chamfering tool body, and is attached to the cutter shaft, which is driven by a drive motor built into the chamfering tool body, and near the tip of the cutter shaft of the chamfering tool body. The chamfering tool is equipped with a chamfer positioning guide mechanism that abuts against a workpiece and defines a chamfering area, wherein the cutter shaft has a hollow shaft shape, and the chamfering part positioning guide mechanism The guide mechanism includes a reference plate that extends across the extending direction of the cutter shaft and has an opening for protruding the tip of the cutter shaft to the front, and one end of which is fixed to the chamfering tool body. At the same time, the other end passes through the hollow part of the cutter shaft and protrudes forward of the tip of the cutter shaft, and a bulge part is formed in the protrusion part to bulge out to a position separated by a predetermined distance from the periphery of the reference plate opening. A chamfering tool comprising a reference member.
