Equipped to tackle both routine and demanding milling tasks, this tool maintains sharpness through powder metallurgy construction and delivers stable cutting action across a broad material range. The combination of a 30° helix and 12° rake angle supports efficient chip formation, reduced rubbing, and smoother finishes in slots and shoulders while minimizing tool wear during ramping. With a precise 13 mm length of cut and a 57 mm overall length, it provides ample reach for depth operations without sacrificing rigidity. Ideal for CNC and manual milling setups that require dependable performance on carbon steels, copper alloys, and high-temperature alloys.
