The Widin Carbide Corner Radius End Mill for Mold & Die is a high-performance cutting tool designed specifically for mold and die machining. With a 3 mm diameter, 20 mm reach and a corner radius of R0.5, this 4-flute end mill uses a variable-index geometry to reduce cutting forces and promote efficient chip evacuation, delivering smoother finishes and longer tool life. The long shank provides stability for deep groove operations and intricate profiles, making it a reliable choice for demanding mold work.

• Variable-index 4-flute geometry: Optimizes edge distribution to reduce cutting forces and improve chip evacuation, yielding smoother cutting action and better surface finishes in complex mold features.
• Corner-radius versatility: Offers extended options for corner radii, including R0.5, so you can tailor profiles to specific mold/die requirements without swapping tools.
• Long-shank design for deep grooves: Provides enhanced reach and stability for deep cavity and groove machining, helping maintain accuracy and reducing tool deflection during aggressive passes.

This end mill supports efficient workflows by delivering consistent results across challenging geometries, helping you finish molds and dies more quickly with reliable tool life and predictable performance. The combination of chip-control, reach, and precise corner radii makes it a practical choice for professional machinists, hobbyists, and production shop environments alike.
