The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and exotic alloys. With a 20 mm cutting diameter and a 1.0 mm corner radius, this tool delivers strong, smooth corners and reliable performance across a range of applications. Built for engineers, machinists, and hobbyists alike, it helps you achieve clean profiles with fewer passes.

Featuring a 3-flute, double-core geometry with a variable helix, it excels at chip control and stable cutting in demanding materials. The unequal index flutes optimize chip evacuation, helping you maintain a smooth workpiece surface and reduce heat buildup during heavy cuts.

• Unequal Index Flutes for Efficient Chip Emission and Smooth Finish: By employing flutes with unequal indexing, this end mill evacuates chips more effectively and helps produce a consistently smooth surface on stainless and exotic alloys, reducing the need for extra finishing passes.
• Double Core Rigidity for Anti-Bending Strength: The double-core design increases the tool's core strength, providing greater stiffness under load, improving resistance to deflection, and delivering more reliable cuts in tough materials.
• Variable Helix with 3 Flutes for Versatility and Stability: The combination of variable helix and three-flute geometry minimizes vibration, improves surface finish, and delivers balanced performance across a range of feeds and speeds when cutting hard-to-machine stainless and exotic alloys.

This end mill is built for dependable long-term performance, helping you maintain tight tolerances, finish high-quality surfaces, and keep your workflow efficient—even when tackling challenging materials. With its robust carbide construction and thoughtful geometry, it’s a trusted choice for precision work in professional manufacturing, job shops, and advanced DIY projects.
