Dormer Pramet C492 10.0mm HSS-E-Powder Metal Alcrona Primax Flatted Shank Multi-Flute Roughing (HRA) Long Series End Mill DIN 844 L

The Dormer Pramet C492 10.0mm HSS-E-Powder Metallurgy End Mill is a long-series roughing tool designed for shoulder and slot milling in a wide range of steels and alloys. It combines a 10 mm Weldon shank, Alcrona Primax coating, and a 4-flute geometry for robust material removal in deep pockets and slots.

The design emphasizes controlled roughing with an asymmetrical fine-pitch profile and a 4-flute layout that balances material removal with chip evacuation. The 35° helix promotes efficient cutting in a variety of materials, while the 12° rake angle aids shoulder milling performance by reducing rubbing and improving surface finish. The HSS-E powder-metallurgy core delivers robust wear resistance and edge stability, enhanced further by the Alcrona Primax coating for reduced friction and longer tool life. With a DIN 844 L shank standard and a generous reach, this end mill is well-suited for deep pockets, shoulder milling, and slotting in common engineering materials.
