The Widin Carbide Corner Radius End Mill is engineered for mold and die manufacturing, delivering precise corner radii and reliable performance in demanding milling applications. This 8 mm diameter tool features a corner radius of R3 and a variable index geometry that enhances machinability and chip evacuation for smoother, more efficient cuts.

Its long shank provides extended reach for deep grooves and hard-to-access features, making it a versatile choice for complex mold cavities and dies. The combination of variable index and 4-flute design supports steady cutting, reduced vibration, and consistent results across materials and production runs.

• Variable index geometry: Reduces cutting forces and improves chip evacuation, delivering smoother cutting and more consistent performance across materials.
• Four-flute design: Increases material removal efficiency and provides stable cutting action for clean corners and contours, helping maintain tight tolerances.
• Long shank with versatile corner radii: Enables deep groove access and accommodates a range of corner radii (including R3) to match mold features and minimize rework.

This end mill is built to boost productivity: predictable tool life, reduced downtime, and cleaner mold surfaces. The long reach lets you tackle deeper cavities in fewer passes, while the optimized edge distribution lowers chatter and supports consistent results from roughing through finishing. For both high-volume production and precise prototyping, this tool helps you complete jobs faster with reliable, repeatable results.
