The Dormer Pramet C922 10.0 mm HSS-E-Powder Metallurgical End Mill is a compact roughing tool designed for demanding metal removal in shoulder milling, slot milling, and ramping applications. Built for professional machinists working with alloy and tool steels, stainless, cast iron, copper alloys, and high-temperature alloys, it delivers reliable performance in a compact 10 mm diameter format.

• Diameter: 10.0 mm
• Length of Cut (LOC): 22 mm
• Overall Length: 72 mm
• Reach / Neck Relief: 31.5 mm reach with neck relief for deep pockets
• Shank: 10 mm Weldon shank, DIN 844 K standard
• Material & Coating: Powder-metallurgical HSS-E with Alcrona Primax coating
• Flutes & Geometry: 3 flutes with an asymmetrical fine-pitch HRA profile, 35° helix, 12° rake
• Intended Operations: Shoulder milling, slot milling, and ramping in a range of metals

This end mill is optimized for efficient roughing in tough materials, offering strong edge retention and consistent performance across a variety of alloys. The Alcrona Primax coating reduces wear and helps maintain a stable cutting action under high load, while the powder-metallurgical HSS-E substrate provides improved toughness and longer tool life compared with conventional high-speed steel. The 3-flute design enhances chip evacuation and material removal rates in short-series machining, making it well-suited for production environments that require repeatable results without frequent tool changes.
