The C922’s asymmetrical fine‑pitch profile and 3‑flute geometry deliver strong material removal with controlled chip formation, making it a dependable choice for heavy roughing passes. The powder‑metallurgical HSS‑E substrate and Alcrona Primax coating resist wear under high cutting speeds and heavy loads, helping to extend tool life and maintain consistent performance across multiple operations. The flatted shank enhances rigidity in standard tool holders, while the extended reach and neck relief enable deeper pockets and shoulder work without interference. This end mill is well suited for production environments that machine a variety of materials—from alloy and stainless steels to cast iron and copper alloys—along with challenging high‑temperature alloys.
