The Dormer Pramet C908 11.0 mm HSS-E powder-metallurgical end mill with Alcrona Primax coating is a compact roughing tool designed for shoulder milling, slot milling, and ramping. With an 11 mm cutting diameter, a 22 mm length of cut, and a 79 mm overall length, it’s built for DIN 844 K machines and features a 12 mm Weldon shank for secure clamping.

• Diameter: 11.0 mm
• Length of cut: 22 mm
• Overall length: 79 mm
• Shank: 12 mm Weldon shank (flatted for secure grip)
• Material & coating: HSS-E powder-metallurgical substrate with Alcrona Primax coating
• NRA geometry: Asymmetrical coarse-pitch profile for efficient roughing
• Flutes: 4 flutes for strong engagement and effective chip evacuation
• Helix & rake: 35° helix and 12° rake angle for shoulder milling, slot milling, and ramping
• Standards: DIN 844 K end mill
• Applications: Roughing in plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper and copper alloys, and high-temperature alloys

This combination of NRA geometry, a robust 4-flute design, and the Alcrona Primax coating translates to efficient material removal, reliable chip control, and extended tool life in demanding machining environments. The tool’s geometry is optimized for high-contact operations like shoulder milling and ramping, delivering consistent performance across a wide range of common engineering materials.
