With high temperature wear resistance, Tiger•tec® Silver PVD Coated Inserts are designed for machining stainless steel, high temperature alloys, and other materials that are difficult to machine. Special surface smoothing on rake face minimizes friction, keeping heat generation in check. Available in WSM10S, WSM20S, and WSM30S grades, inserts offer 3 positive geometries: FM4 for finishing operations, MM4 for universal use including 7° and 11° positive rake, and RM4 for roughing operations.
