Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool designed to tackle hard alloys with confidence. With a 20 mm diameter and a 5.0 mm corner radius, this end mill delivers strong corners and reliable cutting performance in stainless steels and other exotic materials.

Equipped with a 4-flute, variable-helix design and unequal index flutes, it promotes smooth cutting, efficient chip evacuation, and a refined surface finish. This combination makes it a dependable choice for shops that value consistency and long tool life.

• Unequal index flutes for improved chip emission and surface finish: Efficient chip control and a smoother workpiece surface, even in stainless and exotic alloys, thanks to staggered flute spacing that reduces load and helps evacuate chips.
• High-hardness carbide edge for wear resistance: Maintains sharp cutting action in tough materials, delivering longer tool life and reliable performance in demanding applications.
• Corner radius versatility: Available with multiple corner radii to match specific fillet requirements and ensure consistent, accurate corner geometry on finished parts.

Designed to fit into busy shop workflows, this end mill enables repeatable, high-quality results with fewer reworks and interruptions. The combination of durable carbide, thoughtful flute geometry, and flexible corner radius options helps you finish parts faster, maintain tight tolerances, and improve overall machining efficiency when working with stainless steels and exotic materials.
