A tool (10) for deburring cut edges on the opening ends of drillings (12) which open out laterally into cylindrical recesses (14), for example. The tool (10) has a cutting head (22; 122; 222) seated on a shaft (20; 120; 221) with at least one cutting edge (24), running at least partly in the axial direction and which carries out a cutting machining as a result of a relative rotational movement between the tool (10) and workpiece (16). A radial force generation device (30) is integrated in the tool (10) by means of which the cutting head (22; 122; 222), the diameter (DS) of which is selected such as to be able to be introduced into the drilling (12) with radial play (SR), may be preferably controllably extended in the radial direction due to the rotational movement thereof. A support element (32; 38; 42; 44; 52) is provided on the tool shaft (20; 120; 220; 221) by means of which the radial extension of the cutting head (22; 122; 222) may be set within a predetermined range by contact with the inner wall (34) of the drilling (12). |
