The Widin Carbide Corner Radius End Mill is a 4 mm diameter, 45 mm long carbide cutter designed specifically for mold and die machining. Its four-flute configuration features a variable-index geometry that promotes smooth cutting action and efficient chip evacuation, helping you achieve consistent surface finishes even in tight pockets and complex features.

With multiple corner radii available, including R0.2, this tool lets you tailor profiles to each mold feature. The long shank provides the reach and stability needed for deep groove machining, enabling precise, reliable cuts in hard-to-reach areas and intricate cavities.

• Variable Index Geometry for Reduced Cutting Forces: Distributes cutting edges to minimize vibration and workload, delivering smoother cuts and easier chip evacuation for better surface quality.
• Long Shank Design for Deep Grooves and Reach: Provides the necessary reach and rigidity for deep-pocket work, improving stability and accuracy in challenging geometries.
• Corner Radius Versatility for Precise Profiling: Offers multiple corner radii (including R0.2) to match feature geometry, enabling precise, tailored finishes on mold and die components.

This combination supports faster, more predictable machining: cleaner corner profiles, steadier cutting with reduced chatter, and consistent results across complex mold and die features. The tool’s robust carbide construction and thoughtful geometry help extend tool life, reduce rework, and streamline setup for demanding applications.
