The Widin Carbide Corner Radius End Mill for Mold & Die is a high-precision cutting tool designed specifically for mold and die milling. Featuring a variable-index geometry and a 4-flute design, it delivers versatile performance across roughing and finishing tasks, helping you achieve clean corners and smooth surfaces with consistent results.

Designed with a long shank, this end mill reaches into deep grooves and tight pockets where standard tools can’t reach. The corner radius is 0.5 mm (R0.5), enabling smooth fillets on mold features while maintaining tool rigidity and stability during heavy cuts.

• Variable-index geometry: Reduces cutting forces and enhances chip evacuation, delivering smoother cuts and less heat buildup for consistent results across complex mold features.
• 4-flute configuration: Balances material removal with stable cutting action, improving chip control and finishing performance on mold and die surfaces.
• Long shank design: Provides extended reach for deep grooves and hard-to-access pockets, enabling flexible tool paths without frequent tool changes.

This combination of advanced geometry and robust carbide construction delivers reliable, repeatable results in demanding mold-and-die applications. The tool’s design supports efficient chip clearance, reduces downtime, and helps you achieve precise fillets and consistent surface quality—even in deep-pocket work.
