摘要

The tool (1) with a shaft (2) and a cutting insert (4) is provided with a central groove (3) with its sides (8) first parallel positioned and then curved in order to serve as guides (10). Corresponding areas (11) are located at the cutting insert (4) joined to the shaft (2) with at least one axially arranged screw (15). The screw head (17) is positioned mainly above the fixing area (7) of the shaft (2) and overlaps only slightly with the central groove (3).
