Widin Carbide Corner Radius End Mill For Stainless & Exotics - 4 Flute Variable Helix - 5mm x R0.2

The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and other exotic metals. Featuring a 5 mm diameter and a 0.2 mm corner radius (R0.2), this four-flute end mill combines rigidity with refined geometry to deliver reliable performance on challenging materials. The built-in variable-helix design helps maintain stable cuts across a range of feeds and speeds.

Unequal index flute geometry promotes excellent chip emission and a smoother workpiece surface finish, reducing heat buildup and helping you achieve consistent results on hard alloys. This configuration, paired with a tough carbide cutting edge, supports durable performance even in demanding finishing passes.

• Unequal index flute geometry: Improves chip evacuation and heat management, delivering cleaner cuts and a smoother surface on stainless and exotic materials.
• 4-flute carbide with variable helix: Enhances rigidity and minimizes chatter, enabling steadier cuts, better finish, and longer tool life across diverse speeds and feeds.
• 5 mm diameter with R0.2 corner radius: Provides a strong corner radius for durable edges and precise radii in tight corners, reducing edge chipping and improving finishing quality.

This end mill helps you streamline your workflow by delivering fast, repeatable finishes on tough metals. The combination of wear-resistant carbide, optimized flute geometry, and a precise corner radius reduces rework, lowers downtime, and supports reliable performance across manufacturing, machining, and finishing tasks.
