Widin's Carbide Corner Radius End Mill is a precision machining tool tailored for mold and die manufacturing. With a versatile 4-flute design and a variable index geometry, it delivers smooth cutting action and efficient chip evacuation for consistent, high-quality finishes across complex cavities and fillets.

This tool features a 12 mm diameter with a corner radius of R0.3 (R0.3) and a long shank, making it ideal for deep groove work and reaching into tight spaces without losing rigidity. The variable index design optimizes edge distribution to balance cutting forces, reduce vibration, and maintain steady performance throughout demanding mold and die applications.

• Variable Index Geometry for Balanced Cutting: Optimizes edge distribution to reduce cutting forces and improve chip evacuation, delivering smoother machining and longer tool life.
• Long Shank for Deep Grooving: Provides extended reach to access deep pockets and complex cavities without repositioning, boosting productivity and reducing downtime.
• 4-Flute Rigidity for Stable Performance: Four flutes remove material efficiently with minimal vibration, ensuring consistent finishes on mold steels and alloys.

Equipped to handle the precision demands of mold and die work, this end mill helps you achieve precise radii, clean corners, and reliable results across a range of materials. Its combination of corner radius versatility, long reach, and stable cutting makes it a dependable choice for professionals seeking repeatable performance and efficient workflows in high-demand manufacturing environments.
