Patent ID: 11607737

Abstract:
A milling tool for producing chamfer surfaces at workpieces. It has a cylindrical shaft and a cutting part, which has at least two end cutting edges, which are each located on a cone jacket surface and which run in a spiraled convex manner in the direction of rotation, and which each extend from a radially outer cutting corner to an inner cutting corner on the end side. To broaden the area of application of the milling tool to processes, such as the “ramping” or the linear diagonal plunging, respectively, the circular milling, the spot-drilling, or the waterline milling, the end cutting edges merge at the inner cutting corner into center cutting edges, which are located on a cone jacket surface with a tip angle of above 180°, and which run with a positive chip angle into a region of the milling cutter center located in the milling cutter core.
