The Widin Carbide Corner Radius End Mill is a 4-flute carbide cutting tool designed for mold and die work. With a 4 mm diameter and 45 mm overall length, plus a long shank, it delivers the reach and stiffness needed for deep cavities and challenging profiles.

Featuring a corner radius of 0.3 mm and variable index geometry, this end mill promotes smooth cutting and efficient chip evacuation. The variable index distributes cutting edges to reduce forces and heat, helping you achieve a cleaner surface finish and higher machining efficiency. It also offers options for different corner radii, so you can tailor the tool to your specific mold or die geometry.

• Variable index geometry: Optimizes cutting edge distribution to reduce cutting forces and promote efficient chip evacuation, delivering smoother cuts and improved surface finish.
• Long shank design for deep grooves: Provides the reach and stability needed for intricate, deep-cutting operations in mold cavities and channels.
• Corner radius options: Offers multiple corner R sizes to tailor machining to your design specifications, enabling precise fillets and consistent results across complex geometries.

This end mill helps you complete mold and die projects with greater predictability: cleaner surfaces, tighter tolerances, and less downtime from chip clogging. The combination of carbide durability, reach, and adaptable corner radii delivers reliable performance across demanding applications—from pocketing and profile milling to deep grooving—so you can finish parts faster with confidence.
