Widin Carbide Corner Radius End Mill for Mold & Die is a high-performance cutting tool designed for precision work in mold and die machining. It’s built to handle tough materials with consistent results, delivering smooth finishes and reliable tool life in demanding applications.

This end mill features a 4 mm diameter with a 50 mm overall length and a corner radius of 0.3 mm (R0.3), plus a 4-flute, variable index geometry that optimizes edge distribution for reduced cutting forces and efficient chip evacuation.

• Variable index geometry for smoother cutting: Distributes cutting forces across the edge set to minimize vibration, improve surface finish, and promote fast, clean chip evacuation for steady, reliable performance.
• Long shank for deep groove reach: The extended shank provides the necessary reach and rigidity to navigate deep pockets and grooves with minimal deflection, enhancing stability and accuracy.
• Corner radius versatility and 4-flute design: Offers precise corner radii (including R0.3) with a balanced 4-flute configuration that delivers consistent finishes, efficient chip clearance, and reliable performance across mold and die applications.

Designed for professionals across engineering, production, and workshop environments, this end mill helps you complete complex mold and die tasks with fewer passes, less rework, and dependable results. Its combination of corner-radius options, long reach, and optimized cutting geometry supports faster cycles, better surface quality, and longer tool life—making it a reliable choice for demanding machining environments.
