Description
The Widin Carbide End Mill is a purpose-built 4-flute square-edge cutter designed for challenging, high-hardened materials. With a 2 mm diameter and a 25 mm long neck, it offers targeted reach for intricate profiles while maintaining rigidity for precise machining. Built to handle workpieces with draft angles, this long-neck design helps you maintain accurate tool engagement across complex geometries, making it a reliable choice for engineers, machinists, and hobbyists alike.
- Long-Neck Geometry for Draft Angles: The extended neck length provides the necessary clearance for draft angles and longer interference lengths, helping you avoid collisions and maintain consistent depth control on complex profiles.
- Advanced ZSLNS20 Coating for Dry and High-Speed Cutting: Engineered coating and carbide substrate deliver superior heat and wear resistance, enabling dry and high-speed cutting while preserving tool life and dimensional stability.
- Four-Flute Square-Edge for Smooth Finishes: The 4-flute design ensures efficient chip evacuation and stable cutting, producing clean, high-quality surface finishes on hardened materials.
Designed to deliver dependable performance in demanding applications, the Widin end mill helps you shorten cycle times, reduce tool changes, and achieve consistent, high-quality results on hard workpieces. Its robust carbide construction and dedicated coating work together to keep you productive and confident in every pass.
