Claim Text:
1. A milling tool for the hobbing of a workpiece having cogs, such as cogwheels, and racks, comprising: a cylindrical tool body, which defines a rotation axis and including a plurality of disc-shaped segments, each of the plurality of segments including a hub part and a peripheral cam having a plurality of tangentially spaced-apart milling inserts, bordering segments being detachably and torsionally rigidly interconnected, wherein each of the plurality of segments has a through hole situated on the rotation axis, which holes are directed in such a way in relation to each other that a central duct is formed in the cylindrical tool body, the central duct being a cooling medium duct; and a first end piece having opposed sides, one side being detachably and torsionally rigidly interconnected with a first one of the plurality of segments, and the other side having coupling members for torsionally rigid coupling to a source of torque in such a way that all torque from the source is supplied to the cylindrical tool body via only the first end piece.
