The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die work. With a 3 mm diameter, 16 mm length, a 0.5 mm corner radius, and a four-flute design, it delivers smooth cuts and strong edge quality. The tapered neck enhances rigidity for deep grooves, helping you maintain tight tolerances and clean finishes on complex molds and dies.

It is available in multiple specifications to suit different depths and rigidity needs, giving you flexible options for a wide range of projects.

• Four-flute geometry for smoother cuts: The extra flute helps distribute cutting forces more evenly, reducing vibration and delivering finer surface finishes on molds and dies.
• Tapered neck for increased rigidity: The tapered neck design increases stiffness and stability, reducing deflection during deep-groove milling and helping maintain consistent dimensions.
• 0.5 mm corner radius for precise, durable corners: The defined corner radius preserves radii accuracy, reduces corner wear, and extends tool life while delivering crisp, repeatable edges.

By using this end mill, you can achieve reliable, high-quality results across demanding mold and die tasks. The combination of four-flute cutting, tapered neck rigidity, and a precise corner radius translates to smoother finishes, fewer rework passes, and longer intervals between tool changes—helping your shop run more efficiently and confidently.
