The tool characteristics of these milling cutters are the very high toughness because of a new fine grain hard metal, the new tool geometry and a high quality TiAlN coating. NE-Metals (Copper, Al Si alloys), construction and plain carbon steels, alloyed steels and tool steel up to 48 HRc, stainless steel and titanium nickel alloys can be machined with the Qmax without problems. The Qmax allows Economical roughing of both full width and side cutting, with large cut depths and high feed rates.
