Abstract
A milling tool for roughing workpieces is provided with a plurality of cutting flanks and flutes disposed in between. The cutting flanks are provided on the cutting side with a predetermined rake angle, and the cutting edges have moreover a profile of wave form that extends over the width of the cutting flanks. The profile of wave form is provided with a bevel having a width corresponding to at least the height of the crest, and having a wedge angle that is more obtuse than the wedge angle of the milling tool. When the tool is subjected to heavy operational demands, a chipping or breaking off of the crest edges is thereby prevented, thus increasing the service life of the tool.
