Designed to cut cleanly and maintain sharpness through longer runs, this tool leverages cobalt-enhanced HSS-E for superior wear resistance and heat tolerance. The 30° helix supports efficient chip evacuation and smoother cutting action, while the 12° rake angle helps reduce cutting forces during shoulder and slot milling.
