The Widin Carbide Corner Radius End Mill is a 4-flute carbide end mill engineered for mold and die work. It delivers precise corner radii and reliable performance in demanding profiles, making it a versatile choice for engineers, machinists, and serious hobbyists alike.

Its variable index geometry improves machinability and chip evacuation by distributing cutting forces across edges, which helps maintain stable feeds and a smooth finish. The tool also supports a range of corner radii, including R0.5, allowing you to tailor operations to your specific geometry. The long shank provides the reach and stability needed for deep groove machining and intricate pockets.

• Variable index geometry: Optimizes edge distribution to reduce cutting forces and promote efficient chip evacuation, delivering steadier feeds and improved surface finish.
• Corner radius versatility: Offers an extended range of corner radii including R0.5, enabling precise corners and fillets tailored to your mold or die design.
• Long shank design: Provides extra reach and stability for deep groove machining and hard-to-reach features, with improved rigidity and reduced tool deflection.

Together, these features empower you to complete complex mold and die projects more quickly with consistent results. Expect cleaner corners, smoother surfaces, reduced downtime, and greater confidence in achieving repeatable, high-quality tooling outcomes across a range of materials and applications.
