The Dormer Pramet C609 5/8 Inch HSS-E TiCN Flatted Shank Fine Pitch Roughing End Mill Regular Length is a purpose-built tool for aggressive material removal in free‑machining steels and copper alloys. Designed for machinists who demand dependable roughing performance, it combines a robust HSS‑E core with a wear‑resistant TiCN coating to handle demanding milling tasks with consistency.

• Diameter: 5/8"
• Flutes: 4-flute geometry for efficient chip evacuation and rigidity
• Material & Coating: HSS‑E (cobalt‑based) with TiCN coating for enhanced wear resistance
• Shank Type: Weldon 5/8" shank with a flatted section for secure grip
• Length of Cut: 1.625" (1 5/8")
• Overall Length: 3.75" (3 3/4")
• Helix: 30° for smooth cutting in shoulder milling, slot milling, and ramping
• Profile: HR regular fine pitch
• Applications: Shoulder milling, slot milling, and ramping in free‑machining and plain carbon steel and copper/copper alloys
• Standards: ANSI standard compliant

This combination delivers steady performance under heavy stock removal while maintaining control and tool life. The TiCN coating reduces wear and friction, helping to extend tool life in tough materials, and the flat shank enhances seating stability in milling holders for consistent cuts. Ideal for shops performing general roughing duties where reliability and precise geometry matter for predictable material removal in 5/8" tooling.
