The Widin Carbide Corner Radius End Mill is a high-performance cutting tool designed specifically for mold and die machining. With a 4 mm diameter and 20 mm length, this 4-flute carbide end mill delivers precision and durability for professionals working on intricate contours and tight radii.

Its variable index geometry improves machinability by distributing cutting edges to reduce cutting forces and promote smooth chip evacuation, boosting efficiency and delivering a cleaner surface finish. The tool offers multiple corner radius options to tailor fillets and contours to your exact part geometry. The long shank provides extra reach and stability for deep groove machining, enabling precise work in hard-to-reach features without sacrificing rigidity.

• Variable index geometry for efficient cutting: Distributes cutting edges to lower forces and enhance chip evacuation, helping you maintain steady feeds and achieve smoother finishes with less tool wear.
• Corner radius options for precise mold features: Flexible radii (including R0.1) let you match fillets and contours to your mold or die design, reducing secondary operations and improving part quality.
• Long shank for deep groove stability: Extended reach and rigidity support accurate cutting in deep pockets and tight cavities, minimizing deflection and improving repeatability on complex parts.

In practice, this end mill helps you shorten cycle times, reduce finishing passes, and achieve consistent results across challenging mold and die geometries. Its carbide construction and thoughtful geometry are built to withstand demanding materials while preserving edge life, making it a dependable choice for daily production and precision prototyping alike.
