Abstract
A milling tool includes a tool body having a peripheral surface and a central rotation axis. A number of cutting teeth protrude from the peripheral surface, a front end set of the cutting teeth arranged along a front end portion of an imaginary helix concentric with the central rotation axis, and a back end set along a back end portion of the helix. The cutting teeth engage the workpiece successively, starting with the foremost cutting tooth of the front end set. The back end set includes at least three along the helix adjacent cutting teeth arranged at a constant first radial distance from the central rotation axis. The front end set has at least two adjacent cutting teeth arranged at an along the helix non-constant second radial distance from the central rotation axis. The second radial distance is smaller than the first radial distance and increases successively along the helix.
