Widin Carbide Corner Radius End Mill For Stainless & Exotics - 4 Flute Variable Helix - 20mm x R4.0

Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool designed for challenging materials such as stainless steels and other exotic alloys. With a 20 mm diameter and a corner radius of R4.0, it excels in pocketing, finishing, and precise corner work, while the four-flute geometry and variable helix optimize chip control and surface quality for reliable, repeatable results.

• Variable-helix, four-flute design: Unequal index flutes improve chip emission and reduce vibration, helping you achieve a smoother surface finish on stainless and exotic alloys and extend tool life in demanding cuts.
• Hard carbide cutting edge: High hardness provides excellent wear resistance, maintaining sharpness longer and reducing the need for frequent tool changes in tough materials.
• 20 mm diameter with R4.0 corner radius: Delivers strong, clean corners and versatile fillets, enabling efficient pocketing and finishing with repeatable geometry across parts.

This end mill is built to support professionals across the shop floor—from engineers specifying for high-precision work to machinists on the floor delivering consistent, high-quality parts. By combining robust materials with thoughtful geometry, it helps you shorten cycle times, improve surface quality, and rely on dependable performance for stainless and exotic applications.
