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.  

Another key feature is that with its unequal helix angles (35 and 38 degrees) this end mill is able to achieve low vibration operation, boosting tool life and significantly improving surface quality, according to Walter.
 
These features make the Proto·max Inox especially useful whenever high machining rates and superior surface finishes in the machining of materials from the ISO M group are priorities. The mills come in diameter ranges from 6 to 20 mm, with or without corner radii.
