Dormer Pramet C273 10.0mm HSS-E-Powder Metal Flatted Shank Multi-Flute Long Series End Mill DIN 844 L

The Dormer Pramet C273 10.0 mm HSS‑E powder‑metallurgical end mill is a long‑series, four‑flute tool designed for shoulder and slot milling in free‑machining steels and copper alloys. With a robust Weldon shank and extended reach, it delivers precise, reliable milling in tight pockets and deep slots.

• Diameter: 10.0 mm
• Flutes: 4‑flute geometry for stable cutting and effective chip evacuation
• Material: Powder‑metallurgical HSS‑E with bright finish for enhanced wear resistance
• Shank: Weldon shank, Ø10 mm, for secure, repeatable toolholding
• Length and reach: Length of cut 45 mm; overall length 95 mm; reach 54.5 mm with neck relief
• Helix and rake: 30° helix and 12° rake angle optimize cutting action for shoulder and slot milling
• Standard: DIN 844 L compliant for compatibility with compatible holders and setups
• Applications: Suitable for shoulder milling and slot milling in free machining and plain carbon steel and copper/copper alloys

This end mill is built to tackle deep pockets and extended reach tasks without sacrificing rigidity or finish. The combination of HSS‑E powder metallurgy and a bright surface creates a durable cutting edge that stands up to repeated passes in challenging materials. The 30° helix aids chip flow and reduces heat buildup, while the 12° rake angle supports stable engagement during shoulder operations. For shops needing a reliable, long‑reach milling solution on steel or copper alloys, this Dormer Pramet C273 tool offers consistent performance and predictable results across demanding milling cycles.
