Abstract
A milling tool includes a first cutting portion having a first and a second cutting edge extending at the periphery of the first cutting portion along, or following a helical path around, a longitudinal axis of the milling tool. The first and second cutting edges are arranged such that, when the milling tool is rotated around its longitudinal axis, they form respective first and second lines of intersection in a central plane containing the longitudinal axis, wherein the first and the second lines of intersection are arcuate. The extension of the first cutting edge is different from the extension of the second cutting edge such that the first line of intersection is different from the second line of intersection.
