Dormer Pramet C40 14.0mm HSS-E Flatted Shank Multi-Flute Roughing (NF) Standard Length End Mill DIN 844 K

The Dormer Pramet C40 14.0mm HSS-E Flatted Shank Multi-Flute Roughing End Mill is a robust solution for aggressive roughing in free-machining steels and copper alloys. Designed for shoulder milling, slot milling and ramping, it delivers steady performance with a reliable Weldon shank and proven DIN 844 K compatibility.

• Diameter and length: Ø14 mm end mill with 26 mm length of cut, 83 mm overall length, and 37.5 mm reach with neck relief
• Shank: 12 mm Weldon shank for secure clamping and repeatable accuracy
• Material and finish: Cobalt-based HSS-E core with a bright finish for wear resistance and heat tolerance
• Flutes and profile: 4-flute design with NF flat coarse pitch for efficient material removal
• Helix and rake: 30° helix and 12° rake angle optimized for shoulder milling, slot milling and ramping
• Standard: DIN 844 K specification ensures compatibility with standard tool holders
• Applications: Suitable for free machining and plain carbon steel and copper or copper alloys, ideal for roughing stages in multiple machining tasks

This end mill combines a short series geometry with a flat coarse pitch to deliver solid rigidity during aggressive roughing. The 30° helix promotes smooth chip evacuation, while the 12° rake angle helps reduce built-up edge on harder materials. With its 83 mm overall length and neck relief, you gain extended reach without sacrificing stability, making it well-suited for pockets, shoulders, and ramping operations in demanding manufacturing environments. The Weldon shank and DIN 844 K conformity ensure reliable clamping and interchangeability across standard milling setups.
