Equipped with a powder-metallurgical HSS-E substrate and a Primax finish, this end mill offers enhanced wear resistance and toughness for dependable roughing across a range of materials. The 4-flute NRA geometry allows efficient chip evacuation and stable cutting, while the 35° helix and 12° rake angle optimize shearing action for clean shoulders and smooth ramps. The 12 mm Weldon shank provides secure clamping and minimizes runout during heavy cutting passes. Ideal for production environments that demand reliable roughing in steel, cast iron, ferritic, martensitic and super-austenitic stainless steels, duplex or precipitation hardening stainless steels, copper alloys, cast alloys, and high-temperature alloys.
