Designed for versatility and reliability, this end mill delivers efficient material removal with a stable cut across hard-to-machine materials. The four-flute geometry provides a good balance between chip evacuation and finish quality, while the 45° helix promotes smooth cutting action and effective chip control. The 12° rake angle supports shoulder milling and ramping tasks, helping to reduce cutting forces and improve surface finish. The Weldon shank ensures secure clamping in standard milling setups, contributing to consistent accuracy and longer tool life.
