Widia offers new Victory™ WS40PM grade that completes its indexable milling grade portfolio for titanium and stainless steel machining. The indexable grade’s new substrate plus proven PVD coating technology increases performance in rough milling titanium and stainless steels. Excellent toughness and better wear resistance leads to higher efficiency in these demanding applications. New advanced alloyed substrate achieves excellent cutting edge strength and avoids catastrophic insert breakage in severe cutting conditions. It resists thermal cracking that makes it extremely important in machining titanium as coolant is used. WS40PM was designed to meet the needs of the aerospace, defense, and medical industries, where titanium is used for everything from landing gear and seat tracks to lifesaving implants and surgical instruments. Testing results show that WS40PM is suitable for far more than titanium. It can used for machining materials like high-temp steel alloys, austenitic and PH stainless steels, nickel-based super alloys, such as hastelloy and nitronic—these materials cause tool failure due to built-up edge (BUE), cratering, and chipping.
