Abstract
A rotating tool includes a tool body including a polishing tool and a shank, and a flange part provided in the tool body. The polishing tool includes a plurality of linear grinding members and a grinding member holder to hold the linear grinding members. The flange part is an annular member, and attached to the grinding member holder, so as to be movable in the direction of an axial line and rotatable about the axial line. When the inner circumferential surface of a hole formed in a workpiece is processed, the grinding member holder and the annular member are inserted into the hole. When run-out on the front side of the rotating tool occurs, the annular member comes into contact with the peripheral wall surface of the hole, whereby the run-out of the tool body is reduced.
