Abstract
A milling tool for hobbing a workpiece. The milling tool includes a cylindrical tool body having a rotation axis and a plurality of disc-shaped segments. Each of the segments including a hub part and a peripheral cam having a plurality of tangentially spaced-apart milling inserts. Each segment has a through hole situated on the rotation axis. Each of the holes is directed in relation to each other such that a central duct is formed in the cylindrical tool body. Bordering segments are detachably torsionally rigidly interconnected The milling tool also includes a first end piece, which on one side is detachably and torsionally rigidly interconnected with a first one of the segments and which on the other side has coupling members for torsionally rigid coupling to a source of torque, such that all torque from the source is supplied to the cylindrical tool body via the first end piece.
