The Dormer Pramet C407 10.0 mm HSS-E powder-metallurgically enhanced roughing end mill from the Primax line is engineered for high-efficiency roughing in steel, stainless steel, and related alloys. Its NRA asymmetrical coarse-pitch geometry and four-flute design deliver reliable chip control and material removal in shoulder milling, slot milling, and ramping applications.

• Diameter: 10.0 mm
• Flutes & geometry: 4-flute design with NRA asymmetrical coarse-pitch profile for efficient chip evacuation and high material removal
• Length of Cut: 22 mm
• Overall length: 72 mm
• Reach with neck relief: 31.5 mm
• Shank type: DIN 844 K Weldon, 10 mm with a flat (flatted) shank
• Material & finish: Powder-metallurgical HSS-E with bright finish for enhanced toughness and wear resistance
• Helix & rake: 35° helix and 12° rake angle for smooth cutting action and effective chip control
• Applications & compatibility: Shoulder milling, slot milling, and ramping across steels, ferritic/martensitic and super-austenitic stainless steels, duplex and precipitation-hardening stainless steels, cast iron, copper or copper alloys, and high-temperature alloys
• DIN standard: DIN 844 K specification, ensuring standard toolholding compatibility

This end mill is designed to maximize productivity in roughing tasks where aggressive material removal must be balanced with reliable stability. The powder-metallurgy HSS-E construction offers a robust combination of hardness and toughness, while the flat shank provides secure seating in standard holders. The geometry supports efficient ramping and precise shoulder and slot milling, making it a practical choice for mixed-material shops that demand consistent performance and longer tool life when matched with appropriate feeds and speeds.
