The Walter Prototyp Proto·max Inox from Walter USA is a solid carbide end mill that typically boosts stainless steel machining performance by as much as 50 percent when compared with conventional, universal solid carbide end mills, the company says. Walter optimized the end mill for machining ISO M materials such as stainless steel with features such as a four-flute cutter with two internal helical coolant channels for optimized coolant delivery and efficient chip removal—a problem often associated in many stainless steel machining applications.
The Proto·max Inox features a new TAA coating with a TiAlN base and an optimized micro geometry to increase wear resistance and protect against edge build up, the company says. It also provides for a smooth workpiece finish.
