This long-series roughing end mill delivers reliable depth of cut and steady performance in demanding milling operations. The combination of powder-metallurgy HSS-E substrate and Alcrona Primax coating reduces friction, minimizes built-up edge, and extends tool life in tough materials. The 38 mm length of cut provides reach for deeper pockets and wider slots, while the 88 mm overall length keeps your workflow efficient. With its precise geometry and robust construction, it’s a dependable choice for high-precision shoulder and slot milling across a broad spectrum of engineering metals.
