The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed for mold and die machining. It’s built for professionals and hobbyists who demand precise corners, reliable chip evacuation, and smooth, repeatable finishes.

Featuring a 3 mm diameter, 40 mm overall length, and an R1 corner radius, this long-shank end mill provides the reach for deep pockets and intricate cavities while maintaining rigid guidance. The variable-index geometry distributes cutting edges to lower cutting forces and promote efficient chip flow for consistently good finishes across challenging profiles.

• Variable index geometry for smooth cutting: Distributes the cutting load across edges to reduce vibration and heat, improve surface finish, and boost overall machining efficiency.
• Long shank design for deep grooves and reach: Enables access to deep pockets and complex geometries with stable guidance and minimal tool deflection, reducing the need for frequent tool changes.
• Four-flute carbide with precise corner radii: Delivers strong rigidity and efficient material removal, while the R1 corner radius delivers consistent fillets and repeatable corner quality in mold and die features.

This end mill combines robust carbide construction with thoughtful geometry to support reliable performance, longer tool life, and repeatable results across a range of mold and die applications. It helps tighten tolerances, improve finish quality, and streamline workflows by enabling deeper cuts and cleaner corners in a single pass.
