The Widin Carbide Square End Mill for Mold & Die is a high-performance cutting tool designed for precision work in mold and die applications. Featuring a 6-flute, high-helix geometry (45°) and a robust carbide construction, it delivers smooth cutting, efficient chip evacuation, and consistent results across a range of common mold steels and alloys. It is available in a cutting diameter range of 6.0 mm to 20.0 mm with multiple cutting and overall lengths to suit different setups. 6-Flute High-Helix (45°) Geometry: Reduces cutting forces and heat buildup while delivering smooth, efficient cuts and improved chip evacuation for faster, cleaner milling in mold cavities. Precise Diameter Tolerance: Maintains tight control with a tolerance of +0/-0.03 mm, ensuring accurate features and repeatable performance across jobs. W-Coated Carbide for Durability: Extends tool life and stabilizes machining, especially effective for mold and die steels below 55 HRc and for pre-hardened, alloy, and carbon steels. Designed to be reliable and practical, this end mill supports demanding mold and die work while remaining intuitive to use. Its wear-resistant carbide core and protective W coating help you maintain consistent results, reduce tool changes, and keep your machining workflow efficient. Whether you're setting up a new process or upgrading existing tooling, this end mill is a dependable choice for durable performance and precise, repeatable cuts.
