The Dormer Pramet C922 is a 7.0 mm HSS-E powder-metallurgy roughing end mill with Alcrona Primax coating, designed for high-efficiency material removal in tough alloys. It’s optimized for shoulder milling, slot milling, and ramping on alloy and tool steels, stainless steels, cast irons, copper and copper alloys, and high-temperature alloys.

• Diameter: 7.0 mm
• Length of cut: 16 mm
• Overall length: 66 mm
• Shank: Weldon, 10 mm
• Material & coating: Powder-metallurgical HSS-E with Alcrona Primax coating
• Flutes & geometry: 3-flute design with HRA asymmetrical fine-pitch profile, 35° helix, 12° rake
• Standards: DIN 844 K
• Application focus: Shoulder milling, slot milling, and ramping in alloys, tool steels, stainless steels, cast iron, copper alloys, and high-temperature alloys

This end mill blends the toughness of HSS-E with the wear resistance of Alcrona Primax, delivering reliable performance in demanding roughing operations. The 3-flute configuration promotes efficient chip evacuation and steadier cutting in medium-depth passes, while the asymmetrical fine-pitch profile helps maintain stable cutting forces. A Weldon 10 mm shank ensures secure clamping for consistent accuracy, even under heavy workloads. Suitable for shops tackling roughing tasks in diverse metals, it provides a practical, durable solution for cascade milling, pocketing, and aggressive material removal where precision and tool life matter.
