The Widin Carbide Square End Mill is a precision cutting tool designed for mold and die applications. This 2‑flute square end mill pairs a tough carbide core with a W coating to deliver clean, consistent cuts and extended tool life. It’s built for engineers, machinists, and hobbyists who demand reliable performance across challenging materials. Designed with a dedicated gash tooth geometry, it helps prevent flute chipping and promotes smoother chip evacuation, even under demanding cutting conditions. The result is more stable machining, less downtime, and better overall part quality. Gash-tooth geometry to prevent flute chipping: Reduces flute wear and chipping, enabling smoother cuts and longer tool life in tough mold‑and‑die workloads. W coating for extended tool life and stable machining: Improves wear resistance and heat management, delivering longer tool life and steadier performance during high‑speed cutting on harder metals. Broad diameter range with tight tolerance: Cutting diameter range of 0.1m - 20.0mm with a tolerance of +0/-0.012mm ensures precise, repeatable results across jobs, reducing setup time and miscuts. Ideal for mold & die machining on steels below 55 HRc and pre-hardened grades, including alloy and carbon steels, this end mill provides dependable performance, fewer tool changes, and consistent finishes. Its robust construction and thoughtful geometry help you hit tight tolerances with confidence, boosting productivity on every project.
