• Applications: Shoulder milling and slot milling in free-machining and plain carbon steel and copper or copper alloys

With its generous reach and neck relief, this end mill maintains rigidity while accessing deep features, helping you achieve accurate shoulders and clean slots without frequent tool changes. The 4-flute configuration optimizes chip control and surface finish, particularly on tougher materials, while the HSS-E powder metallurgy core provides a balance of hardness, toughness, and wear resistance for longer tool life in industrial milling environments. The bright finish aids in chip flow and reduces built-up edge, contributing to steadier cuts and consistent results across multiple passes.
