PROBLEM TO BE SOLVED: To provide a deburring tool capable of removing burrs of only required place, without damaging a work surface such as an inner surface of a work through-hole.SOLUTION: In a columnar body 1, a holder storing chamber 3 is formed so as to open to an outer peripheral surface of the columnar body 1. A holder 4 is stored in the holder storing chamber 3 so as to slide in an orthogonal direction to an axis of the columnar body 1. A blade tool 5 is attached to the holder 4 while projecting a tip end portion to a side part. With a part of an outer peripheral portion of the columnar body 1, an air supply ring 6 is externally fitted while permitting rotations of the columnar body 1. An air annular passage 7 formed in the inside of the air supply ring 6 communicates with the holder storing chamber 3 through an air passage 8. When pressure air supplied through the air supply ring 6 is supplied to the holder storing chamber 3, the holder 4 slides in a direction projecting out the tip end portion of the blade tool 5 against the energizing force of a pullback spring 14. |
