Meet the Dormer Pramet C907 12.0 mm end mill — a high-performance HSS-E tool with Alcrona Primax coating, engineered for shoulder milling, slot milling, and ramping. Designed for professionals who demand reliability in steel, stainless steel, cast iron, and challenging alloys, it pairs robust geometry with long reach for deeper pockets and precise finishes.

• Diameter: 12.0 mm
• Flutes: 4-flute geometry for efficient chip evacuation and stable cutting
• Length of cut: 26 mm, suitable for shallow to mid-depth milling
• Overall length: 83 mm with neck relief for controlled engagement
• Reach / neck relief: 37.5 mm reach to access tight pockets
• Shank: 12 mm Weldon shank with a flatted section for secure seating in holders
• Coating / material: Powder-metallurgical HSS-E with Alcrona Primax coating for enhanced wear resistance
• Helix & rake: 45° helix and 12° rake angle optimized for shoulder milling, slot milling, and ramping
• Standard: DIN 844 K compliant for reliable interchangeability
• Applications: Shoulder milling, slot milling, and ramping across a range of materials
• Materials compatibility: Plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper and copper alloys, and high-temperature alloys

This end mill is built to handle demanding operations with a balance of depth, rigidity, and control. The 4-flute design provides steady chip management and a smooth finish, while the Alcrona Primax coating reduces wear and helps maintain precision over extended cutting cycles. The combination of a Weldon shank and a flatted section ensures a secure seat in the holder, minimizing runout during high-speed milling. With its versatile reach and DIN-standard sizing, it’s well-suited for machining pockets, shoulders, and ramps in a variety of common engineering materials, making it a dependable choice for both job shops and production environments.
