The Widin Carbide Corner Radius End Mill is a 10 mm diameter, 4-flute carbide end mill with a corner radius of R1. It features variable-index geometry that optimizes cutting edge distribution for mold and die manufacturing, delivering smoother cuts and efficient chip evacuation. With a long shank and a wide range of corner radii (including R1), it adapts to complex cavities, deep grooves, and tight fillets, reducing setup time and increasing versatility.

• Variable-index geometry for smoother cuts: The varied spacing of cutting edges reduces chatter and cutting forces while improving chip evacuation for cleaner, more predictable results.
• Four-flute design for stable, efficient cutting: Balances material removal with surface finish and provides robust rigidity to support higher feed rates in mold-and-die work.
• Deep-reach capability with corner-radius versatility: Long shank enables access to deep pockets and complex cavities, while a range of corner radii (including R1) lets you tailor the tool path to your feature geometry.

Designed for reliable, repeatable performance, this end mill helps you achieve cleaner corners, smoother surfaces, and fewer tool changes in mold and die applications. The carbide construction delivers wear resistance for demanding materials, while the geometry supports consistent chip control and predictable results across a variety of depths and feature sizes.
