Widin Carbide Corner Radius End Mill for Mold & Die — a precision carbide tool designed for mold and die manufacturing. It features a 12 mm diameter with a corner radius of R0.3, delivered in a 4-flute, variable-index configuration for versatile milling across profiles, pockets, and fillets. The long shank provides extended reach for deep groove work without sacrificing rigidity, making it suitable for challenging cavities and long channels.

Thanks to its variable index geometry, this end mill optimizes cutting edge distribution to reduce cutting forces and enhance chip evacuation. The result is smoother operation, cooler cutting, and more efficient material removal. A wide range of corner radii are available, letting you select the exact radius needed for precise tolerances and clean wall finishes.

• Variable Index Geometry for Smoother Cutting: Distributes cutting forces across the edges and improves chip evacuation, delivering smoother cuts and less tool wear in mold and die profiles.
• Four-Flute Design for Efficient Material Removal: Balances rigidity with effective chip clearance, enabling reliable roughing and finishing with consistent surface quality.
• Long Shank with Flexible Radius Options: Provides extended reach for deep grooves and a wide range of corner radii, giving you the flexibility to choose the exact fillet size without changing tools.

With this end mill, you gain dependable, repeatable performance for demanding mold and die work. The combination of variable index dynamics, a robust 4-flute design, and a long reach delivers smoother cuts, better chip control, and the flexibility to achieve precise radii and clean walls—helping you improve throughput, reduce rework, and maintain high part quality across productions.
