Dormer Pramet C922 8.0mm HSS-E-Powder Metal Alcrona Primax Flatted Shank Multi-Flute Roughing (HRA) Standard Length End Mill DIN 844 K

Engineered for robust roughing, the Dormer Pramet C922 8.0 mm HSS‑E end mill delivers dependable material removal for shoulder milling, slot milling, and ramping in a range of hard metals. Built on a powder‑metallurgical HSS‑E core with an Alcrona Primax coating, this 3‑flute tool is designed to perform reliably in alloy steels, stainless steels, cast iron, copper and copper alloys, and high‑temperature alloys.

• Applications: Shoulder milling, slot milling, and ramping in alloy steel, tool steel, stainless steel, cast iron, copper/copper alloys, and high‑temperature alloys

The combination of a 35° helix and a 12° rake angle enhances chip evacuation and yields steady cutting forces, helping you maintain dimensional accuracy even on aggressive roughing passes. The 10 mm Weldon shank provides a robust interface with common toolholding systems, reducing runout and vibration. Thanks to its Alcrona Primax coating and powder‑metallurgical HSS‑E substrate, the C922 end mill balances wear resistance with toughness, enabling longer tool life and reliable performance across multiple materials without sacrificing finish quality.
