The Widin Carbide Square End Mill is a 2-flute cutting tool with a square end and a W coating, built for mold and die work. It covers a broad diameter range—from 0.1m to 20.0 mm—with a tight tolerance of +0/-0.012 mm, helping you maintain precise features across multiple parts. Designed for engineers, machinists, and hobbyists alike, this end mill combines durable carbide with a wear-resistant W coating to extend tool life and stabilize cutting when working with hard steels and alloy steels commonly found in mold and die applications. Long-lasting W coating for wear resistance: The W coating reduces wear and maintains cutting performance, delivering longer tool life and steadier results in demanding materials. Gash tooth design to prevent flute chipping: Specially shaped gashes minimize flute chipping and improve chip evacuation for consistent, reliable cuts even in tough workpieces. Precise diameter range with tight tolerance: With a cutting diameter range of 0.1m to 20.0 mm and a tolerance of +0/-0.012 mm, you get dependable sizing and repeatable pockets for molds and dies. This end mill helps you streamline production with repeatable pocket dimensions, cleaner edge finishes, and fewer tool changes. Its carbide core and W coating are optimized for mold and die work up to 55 HRc, including pre-hardened steel, alloy steel, and carbon steel, delivering reliable performance and consistent results across demanding applications.
