Widin Carbide Corner Radius End Mill for Mold & Die is a high-performance 4-flute carbide milling tool designed specifically for mold and die applications. With a 4 mm diameter and a 45 mm overall length, this end mill delivers the reach and rigidity needed to tackle deep pockets, complex cavities, and fine features with confidence.

Its variable index geometry optimizes edge distribution to lower cutting forces and promote smooth chip evacuation, delivering faster material removal and a better surface finish. The tool also offers multiple corner radius options, including R0.1, so you can tailor corners to match your mold or die design without additional tooling.

• Variable-Index Geometry: Reduces cutting forces and improves chip flow for faster, more consistent machining and markedly better surface finishes.
• Extended Reach with Long Shank: Provides stability and access to deep grooves and tight features, reducing deflection and tool wear during demanding passes.
• Versatile Corner Radius Options: Offers multiple radii, including tight R0.1 corners, to precisely finish intricate profiles and minimize secondary finishing steps.

Designed for reliability and repeatable results, this end mill supports efficient workflows from roughing to finishing. Its carbide construction withstands challenging mold and die materials, while the optimized geometry minimizes heat and extends tool life. The combination of depth reach, stable cutting, and tailored corner radii helps you achieve consistent tolerances, smoother surfaces, and fewer tool changes—so you can complete complex parts faster and with greater confidence.
