PROBLEM TO BE SOLVED: To provide a deburring tool that removes burrs or a distortion, generated or occurring when machining a workpiece being an object to be machined without chamfering the end edge of the workpiece. SOLUTION: The deburring tool 10 is equipped with: a body 21 having a cutting edge 26 in which each blade line 27a extends radially on the tip surface 25 orthogonal to the rotational center axis L; and a guide 31 extended from the tip surface 25 coaxially with the body 21. Each groove 34 is formed in which a pair of opening end edges extends in the axial direction of the guide 31. The pair of opening edges is notched from the peripheral surface 33b of the guide 31 in the inner peripheral direction so as to face each other. The guide 31 is inserted into a hole P of a workpiece W and rotated so as to bring each groove 34 formed in the guide 31 into sliding contact with the opening end surface of the hole P or to allow each groove to strike the opening end surface. The hole P is deburred thereby. COPYRIGHT: (C)2011,JPO&INPIT
