The tool for producing undercuts (12) has a support body (1) set in rotation and a cutting blade (2). The cutting blade (2) is supported with a supporting surface (4) on the base (3) of a recess in the support body (1). The base (3) and the supporting surface (4) are inclined increasingly away from the free end face (6) of the support body (1). Consequently, when the support body (1) is displaced, the area of the cutting blade (2) opposite the supporting surface (4) is deflected, while the end face (11) rolls without radial displacement on the bottom (12a) of the blind hole (12). <IMAGE>
