The invention relates to a milling and boring tool (1) comprising a tool shaft (3) that has a central axis (5), at least one geometrically-defined roughing cutting edge (7), and at least one geometrically-defined finishing cutting edge (13), said at least one roughing cutting edge (7) and at least one finishing cutting edge (13) each comprising a flute (9; 15). The milling and boring tool (1) is characterised in that the flute (15) of the at least one finishing cutting edge (13) has a helix inverse to that of the flute (9) of the at least one roughing cutting edge (7). |
