Abstract
An extremely useful rotating tool is provided that can prevent rattling caused by a clearance between a machine tool and a machine tool retaining hole while bringing the axial center position of the machine tool and the axial center position of the machine tool retaining hole as close together as possible. The present invention is a rotating tool having a rotating main shaft (), and the rotating main shaft () is provided with a machine tool retaining hole () having a cross-sectional shape that substantially matches a base part () of a driver bit, drill bit, or other machine tool () having a polygonal cross-sectional shape that is inserted into the machine tool retaining hole (), wherein the rotating tool rotates the machine tool () inserted in the machine tool retaining hole () by rotating the rotating main shaft () and performs work. A pushing mechanism is provided for rotating the machine tool () in a prescribed direction and twisting and pushing the machine tool () against an internal surface of the machine tool retaining hole ().
