Abstract: The invention relates to a rotary cutting tool (3) that is composed of a tool shank (2) with at least one chucking groove (5) and one exchangeable cutting insert (1). At the tip (4) of the shank as well as in the wall of the chucking groove (5) a recess (6) for accommodating the cutting insert (1) is provided and is delimited on the shank-end by a rim (7) against which the shank-end narrow side (12) of the cutting insert (1) rests. The cutting insert (1) comprises a fastening pin (15) which is accommodated in a location opening (16) of the tool shank (2) that is concentric to the tool axis (A). The tool shank (2), on its circumference, has a limb (9) with a bearing surface (8) that is inclined relative to the tool axis (A) and that corresponds to a likewise inclined bearing surface (10) on a wing (11) of the cutting insert (1). The orientation of inclination of the bearing surfaces (8, 10) corresponds to the direction of rotation (D) of the tool. The inclination of the bearing surfaces (8, 10) produces an axial force that retains the cutting insert (1) on the tool shank (2).
