The Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool designed to create accurate corner radii and smooth surface finishes on tough materials. With a 20 mm diameter and a 0.5 mm corner radius, this 3-flute, double-core, variable-helix end mill is ideal for engineers, machinists, and serious hobbyists working with stainless steel and exotic alloys. Its unequal index flutes promote excellent chip evacuation and help deliver a consistent, blemish-free finish.

• Unequal index flutes for excellent chip emission: The staggered flute spacing enhances chip flow and reduces heat buildup, helping you achieve a smooth surface finish on stainless and exotic materials.
• Three-flute, double-core design for rigidity: This combination provides anti-bending strength and stable cutting under demanding loads, improving tool life and consistency across jobs.
• Variable helix for reduced chatter and better finish: The evolving helix angles minimize vibration, delivering cleaner corners and more uniform surfaces on challenging alloys.

Designed to deliver reliable, repeatable results, this end mill helps you complete precise corner radii with confidence. The robust carbide construction, combined with chip-control optimization and rigidity, supports efficient workflows, fewer reworks, and dependable performance across production and prototyping work with stainless steel and exotic materials.
