PROBLEM TO BE SOLVED: To provide a deburring tool easily mounted to a hole of a workpiece and capable of efficiently removing burrs at the rear side of the workpiece from a surface side.SOLUTION: The deburring tool 10 removes the burrs 3 at the rear side generated during drilling 2 of the workpiece 1 from the surface side. The deburring tool 10 includes an outer cylinder 11 inserted into the hole 2, an operating shaft 12 that is movable in an axial direction to the outer cylinder 11 and is relatively nonrotatably fitted thereto, deburring chips 15 freely turnably mounted in a plurality of openings 13 formed in a circumferential direction at intervals at the tip part of the outer cylinder 11 through a pivot pin 14 and appearable at a use position where they are projected to the outside of the outer cylinder 11 and at a storage position where they are stored in the outer cylinder 11, and switching means 16 arranged at the operating shaft 12 and the deburring chips 15 and allowing the deburring chips 15 to be switched to the use position and the storage position by the operation of the operating shaft 12 in the axial direction. |
