Engineered for aggressive roughing, the Dormer Pramet C492 8.0 mm end mill combines a powder-metallurgical HSS-E core with an Alcrona Primax coating for outstanding wear resistance and long tool life. The long-series design and rugged geometry make it a reliable choice for demanding shoulder and slot milling on a wide range of materials.

• Diameter and reach: 8.0 mm diameter with 38 mm length of cut and 88 mm overall length (DIN 844 L) for deep pockets and extended reach
• Flutes and geometry: 3-flute configuration with an asymmetrical fine pitch profile (HRA), 35° helix and 12° rake for efficient material removal and smooth evacuation
• Shank design: 10 mm Weldon shank with a flattened section for secure clamping and precise alignment
• Material and coating: Powder-metallurgical HSS-E core with Alcrona Primax coating to enhance wear resistance and heat fatigue life
• Typical applications: Shoulder milling and slot milling in plain carbon steel, alloy and tool steel, stainless steel, cast iron, copper and copper alloys, and high-temperature alloys
• Construction standard: Complies with DIN 844 L for consistent interchangeability and compatibility with standard tool holders

This end mill is designed to deliver stable, high-efficiency performance in tough machining environments. The combination of a robust HSS-E substrate, advanced Alcrona Primax coating, and precise three-flute geometry reduces chatter, improves chip evacuation, and extends tool life—helping you complete demanding roughing operations with confidence. Ideal for shops seeking reliable, long-reach milling solutions that handle a broad material spectrum without frequent tool changes.
