Designed for precise milling in free‑machining steels and a broad range of alloys, the Dormer Pramet C246 11.0 mm HSS‑E end mill combines a powder‑metallurgical substrate with a TiCN coating for dependable performance in shoulder, slot, and ramp milling.

• Diameter: 11.0 mm
• Flutes: 4‑flute design for efficient chip evacuation and stable cutting
• Length of Cut: 22 mm
• Overall Length: 79 mm
• Shank: Weldon (flatted) shank, 12 mm for secure clamping
• Material / Coating: HSS‑E powder‑metallurgical substrate with TiCN coating for wear resistance
• Helix Angle: 30° for balanced cutting action in shoulder and slot milling
• Rake Angle: 12° to optimize cutting efficiency and chip flow
• Standards: DIN 844 K compatible, designed to fit common toolholders
• Applications: Shoulder milling, slot milling, and ramping on free‑machining plain carbon and alloy steels, cast iron, copper or copper alloys, and titanium or titanium alloys

The combination of a 30° helix and a 12° rake angle supports steady cutting forces and effective chip evacuation, while the TiCN coating reduces wear and friction during higher‑feed milling. The PM‑HSS‑E substrate delivers a fine grain structure and reliable toughness, helping maintain accuracy across longer production runs. With a forgiving cutting geometry and a robust Weldon‑style shank, this end mill remains stable under demanding engagements, delivering clean shoulders, precise slots, and smooth ramps in a variety of workpieces.
