SW and FW – Reduction Gear – T515


Due to the uniquely designed wiper edge with radius shape, SW chipbreaker increases productivity by 1.5 times compared to the competitor’s regular insert without wiper.Long tool life- T515, highly versatile grade for cast iron turning, improves wear resistance as the Al2O3 layer is thicker than that of the conventional product, leading to stable machining and doubled tool life even in machining FCD800.
