The Widin Carbide Corner Radius End Mill for Mold & Die (12 mm diameter, corner radius R4) is a precision cutting tool engineered for mold and die work. Its variable-index, 4-flute geometry delivers versatile, efficient milling with smooth finishes and reliable chip control.

The long shank provides extended reach for deep grooves and tight cavities, while the option of multiple corner radii gives you the flexibility to match the exact profile your mold or die feature requires.

• Variable-index geometry for smoother cuts: Optimizes edge distribution to reduce cutting forces and improve chip evacuation, helping maintain surface quality and reduce vibration during high-speed milling.
• 4-flute design for efficient material removal: Balances rigidity with generous chip clearance, enabling higher feed rates and more consistent finishes across complex profiles.
• Long shank for deep grooves and hard-to-reach features: Extended reach plus stable guidance supports accurate profiling in deep pockets and intricate cavities without sacrificing rigidity.

Designed for reliability in demanding mold and die applications, this end mill helps you achieve precise corner radii with fewer passes and repeatable results. Its carbide construction and optimized geometry are tailored to deliver steady performance, reduce downtime, and support consistent outcomes across challenging cavity geometries.
