The Dormer Pramet C247 12.0 mm HSS-E-Powder End Mill is a high-performance milling tool designed for shoulder milling, slot milling and ramping in free‑machining steels and copper alloys. With a robust 12 mm Weldon shank and a precise 4-flute geometry, it delivers reliable cuts and consistent finishes in demanding work kicks.

• Diameter: 12.0 mm
• Flutes: 4-flute design for efficient material removal and smoother engagement
• Cutting length (LOC): 26 mm, optimized for pocketing and profiling tasks
• Overall length: 83 mm with neck relief for controlled reach
• Reach: 37.5 mm neck relief to access deeper features while maintaining rigidity
• Shank: 12 mm Weldon shank for secure clamping and repeatable positioning
• Material and finish: HSS-E produced by powder metallurgy with a bright finish for wear resistance and easy chip evacuation
• Helix and rake: 30° helix and 12° rake angle optimized for shoulder milling, slot milling and ramping
• Standard: DIN 844 K, ensuring compatibility with standard tool holders and equipment
• Applications: Suited for free machining and plain carbon steels as well as copper and copper alloys

Designed to maximize productivity, this end mill combines a robust flute geometry with precise angle geometry to deliver clean shoulders, accurate slots, and smooth ramping. The 30° helix promotes efficient chip evacuation at higher feed rates, while the 12° rake angle helps reduce cutting forces during shoulder milling. The powder‑metallurgically produced HSS‑E offers improved hardness and wear resistance, extending tool life in challenging materials. With its DIN 844 K compatibility and a secure 12 mm Weldon shank, this end mill provides reliable performance in standard milling machines and fixtures, making it a solid choice for workshop environments that require consistent results, reduced setup time, and predictable tooling costs.
