Dormer Pramet C407 14.0mm HSS-E-Powder Metal Primax Flatted Shank Multi-Flute Roughing (NRA) Standard Length End Mill DIN 844 K

The Dormer Pramet C407 14.0 mm HSS-E-PM roughing end mill is a compact, high‑efficiency tool built for demanding roughing and shifting operations. Designed for shoulder milling, slot milling, and ramping, it combines an NRA asymmetrical coarse-pitch profile with a four‑flute geometry to optimize chip control and material removal in tough materials.

The combination of a powder‑metallurgical HSS‑E substrate and a Primax finish provides robust wear resistance and toughness for tough machining tasks. The 35° helix and 12° rake angle are optimized for stable cutting movements during shoulder and slot milling, while the short, stout geometry supports strong plunge and ramping performance in a variety of machines. With a DIN 844 K Weldon shank, it offers secure clamping and consistent precision in every pass, making it a reliable choice for production environments that demand steady material removal and predictable tool life.
