The Dormer Pramet C246 5.0 mm HSS-E end mill is a precision cutting tool designed for shoulder milling, slot milling, and ramping. Built for reliability on free-machining steels and non‑ferrous materials, it delivers steady performance with efficient chip control.

• Flutes: 4-flute design for smooth cutting action and effective chip evacuation
• Diameter: 5.0 mm
• Length of cut: 13 mm
• Overall length: 57 mm
• Shank: 6 mm Weldon shank, DIN 844 K conformity
• Coating / material: HSS-E (powder metallurgy) with TiCN coating for wear resistance
• Helix and rake: 30° helix and 12° rake angle optimized for shoulder milling and ramping
• Shank style: Flatted shank for secure grip and precise clamping
• Applications: Shoulder milling, slot milling, ramping in free machining steel, cast iron, copper or copper alloys, and titanium or titanium alloys

This end mill is engineered to withstand demanding machining tasks while maintaining stable tool engagement and predictable wear. The TiCN coating reduces wear on abrasive materials, while the powder-metallurgy HSS-E substrate offers a balance of hardness and toughness. With a DIN 844 K shank standard, it fits a wide range of collets and holders, providing reliable compatibility across common CNC setups. Whether you’re removing material from tight pockets or finishing shoulders, this tool delivers consistent results with clean chip formation and good surface integrity.
