Designed to handle long cutting runs with stability, this end mill minimizes deflection during deep pockets and tight shoulders. The four-flute configuration strikes a balance between rapid material removal and chip evacuation, helping to maintain consistent tool life and steady feeds during roughing passes. The Alcrona Primax coating reduces wear and heat buildup, enabling repeatable performance across challenging materials. Whether you’re profiling, slotting, or pocketing, the C948 Long Series is built to deliver reliable, high-coverage roughing with a clean breakout and durable performance in CAM workflows.
