Abstract
A tool for fine machining of work pieces involving metal removal is proposed having at least one cutter (13) for preliminary machining with a geometrically defined cutting edge (15) and having at least one cutter (21) for final machining with a geometrically defined cutting edge (23). The characteristic of the tool is that the cutter (13) for preliminary machining is part of a preliminary machining stage (3) and the cutter (23) for final machining is part of a final machining stage (5) and that an interface (9) located between the preliminary machining stage (3) and the final machining stage (5) is provided with a first flat surface (27) and a second flat surface (29) which are located on the preliminary machining stage (3) and the final machining stage (5) and which has a device (11) ensuring the coaxiality of the preliminary machining stage (3) and the final machining stage (5) to each other.
