Coated inserts are used for machining of stainless steels because of the resistance against the weldability of the chips with the tool face. This article deals with the adhering of the work material to the tool face during machining with coated inserts. The adhering material was evaluated by the difference between the geometry of the cutting edge and the valleys of the machined surface profile. The adhering material to the cutting edge actually cut the work piece even when the surface profile had the regular feed mark. The adhering material / built up edge was observed at the end of the chips.
