A tool for removing burrs detects whether the depths of holes (81, 82, 83) made on a work (W) are prescribed depths or not. The tool (30) for removing burrs includes a tool case (31) and a piston (3) stored to move to and fro in the tool case. The piston has a spindle (12) arranged at its leading end. A judging section (61) judges whether the depth of the hole is normal or not, based on the results of the detection of whether the piston is retracted relatively to the tool case by a piston position detecting mechanism (56) and those of the detection of existence of the tool case by the tool case position detecting means (32).
