Dormer Pramet C407 6.0mm HSS-E-Powder Metal Primax Flatted Shank Multi-Flute Roughing (NRA) Standard Length End Mill DIN 844 K

The Dormer Pramet C407 6.0 mm HSS‑E powder metallurgy end mill is a compact roughing tool designed for real-world metalworking. With an NRA asymmetrical coarse pitch profile and four cutting flutes, it excels at aggressive material removal in shoulder milling, slot milling, and ramping applications.

• Diameter: 6.0 mm
• Length of cut (LOC): 13.0 mm
• Overall length (OAL): 57.0 mm
• Flutes: 4
• Shank: 6.0 mm Weldon shank with flatted shank geometry
• Material and coating: HSS‑E, powder metallurgy (PM) with Primax bright finish
• Chipbreaker profile: NRA asymmetrical coarse pitch for efficient chip control
• Helix and rake: 35° helix, 12° rake angle for shoulder milling, slot milling and ramping
• Standard: DIN 844 K
• Applications: Shoulder milling, slot milling, and ramping in steel, cast steel, ferritic, martensitic and super‑austenitic stainless steels, duplex or precipitation hardening stainless steels, cast iron, copper and copper alloys, and high‑temperature alloys

This short series roughing end mill is designed for reliable performance in tough materials, delivering consistent tool life and stable chip formation. The combination of powder‑metallurgical HSS‑E substrate and Primax coating provides robust wear resistance, while the flatted shank enables secure seating in standard toolholders to minimize runout during high‑demand roughing passes. Ideal for shops that handle a variety of steels and high‑temperature alloys, it balances aggressive material removal with predictable results across common roughing tasks.
