Widin Carbide Corner Radius End Mill is a versatile 4-flute carbide tool designed for mold and die work. With a variable index geometry and a 4 mm diameter, it delivers smooth cutting and efficient chip evacuation across complex cavity features. Its long shank provides extended reach for deep grooves, making it a reliable choice for demanding mold and die applications.

This end mill features a corner radius option (R0.1) and a wide range of other corner radii, allowing you to tailor each pass to your specific feature. The combination of variable index geometry and four cutting edges enhances stability and material removal, helping you achieve consistent results with fewer passes and less chatter.

• Variable index geometry: Optimizes cutting edge distribution to reduce cutting forces and improve chip evacuation, yielding smoother operation and longer tool life.
• Corner radius versatility with 4-flute design: Wide range of corner radii available paired with a robust 4-flute configuration for efficient material removal and reliable finishes on mold/die cavities.
• Long shank for deep groove reach: Extended reach lets you access deep pockets and tall features without frequent tool changes, improving workflow on multi-axis setups.

Designed for engineers, machinists, and hobbyists alike, this end mill helps you standardize tooling across parts, reduce downtime, and achieve precise radii and smooth surfaces in molded components. Its carbide construction and thoughtful geometry deliver dependable performance in demanding mold and die tasks, so you can work faster with more predictable results.
