Dormer Pramet C908 25.0mm HSS-E-Powder Metal Alcrona Primax Flatted Shank Multi-Flute Roughing (NRA) Standard Length End Mill DIN 844 K

The Dormer Pramet C908 25.0 mm HSS-E powder-metallurgical end mill with Alcrona Primax coating is built for heavy metal removal, designed for shoulder milling, slot milling, and ramping across a range of tough materials. Its NRA asymmetrical coarse pitch with six flutes delivers productive roughing performance with a steady, long-reach geometry.

• NRA profile: Asymmetrical coarse pitch for efficient material removal
• Coating / Material: Powder-metallurgical HSS-E with Alcrona Primax
• Shank: Weldon 25 mm
• Length of Cut: 45 mm
• Overall Length: 121 mm
• Reach / Neck relief: 64.5 mm reach with neck relief
• DIN standard: DIN 844 K
• Helix / rake: 35° helix and 12° rake angle
• Applications: Shoulder milling, slot milling, and ramping
• Material compatibility: Plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper and copper alloys, and high-temperature alloys

The tool combines a robust 25 mm diameter with a long reach to tackle deep pockets and through-slots, while neck relief provides clearance to prevent rubbing on workpiece surfaces during aggressive cuts. The Alcrona Primax coating reduces wear and friction, helping maintain dimensional accuracy and extend tool life under demanding roughing passes. With the 35° helix and 12° rake, it promotes steady chip control and efficient material removal across a variety of metals, making it a reliable choice for productive milling operations where consistency and longevity matter.
