The Dormer Pramet C609 1-Inch HSS-E TiCN Flatted Shank Fine Pitch Roughing End Mill is a purpose-built tool for precise, high-arity roughing in steel and copper alloys. Designed for shoulder milling, slot milling, and ramping, it delivers dependable performance in demanding CAM programs and production environments.

• Diameter & Flute Count: 1" diameter with 5 flutes for efficient material removal and stable cutting
• Material & Coating: HSS-E cobalt-based steel with TiCN coating for improved wear resistance and longer tool life
• Shank Style: 1" Weldon shank (flatted) for secure seating and accurate alignment in holders
• Length Details: 2" length of cut; 4.5" overall length, ANSI standard
• Geometry: 30° helix optimized for shoulder milling, slot milling, and ramping
• Profile: HR regular fine pitch profile to balance chip formation and rigidity
• Applications: Effective for free-machining and plain carbon steel as well as copper or copper alloys
• Brand & Series: Dormer Pramet C609 line, engineered for consistent performance in roughing passes

This end mill is built to handle aggressive roughing without sacrificing control. The TiCN coating reduces built-up edge and enhances wear resistance, while the cobalt-based HSS-E core provides toughness under heavy cutting loads. The flatted Weldon shank minimizes slippage in chucks and collets, helping maintain stable engagement during shoulder milling and ramping. With its precise 1" diameter and 2" length of cut, it’s a reliable choice for production environments that require predictable tool life and consistent chip evacuation. Ideal for processing free-machining steels and copper alloys, it supports efficient removal of material while maintaining dimensional accuracy and surface consistency.
