The Widin Carbide Corner Radius End Mill for Stainless & Exotics is designed for precision work on hard materials. With a 12 mm cutting diameter and a 1.5 mm corner radius (R1.5), this 4-flute end mill uses a variable-helix geometry to deliver clean corners and smooth pockets in stainless steel and exotic alloys.

Featuring unequal index flutes for excellent chip emission and a smooth workpiece surface finish, and a high-hardness carbide cutting edge for outstanding wear resistance, this tool holds up under demanding conditions. It also supports various corner radius sizes to match your specific application needs.

• Unequal index flutes for efficient chip emission and smoother surface finish: The staggered flute pattern promotes quick chip evacuation, reducing heat buildup and leaving cleaner pockets on stainless and exotic metals.
• High-hardness carbide cutting edge for wear resistance: Built to maintain sharpness longer in hard materials, delivering consistent cuts and longer tool life.
• 4-flute variable-helix design with flexible corner radii: Balances cutting forces, reduces vibration, and supports multiple corner radius sizes to fit diverse machining needs.

This end mill helps you complete precise contouring and corner work with fewer tool changes, less rework, and reliable performance across stainless and exotic materials. The combination of chip-control, edge hardness, and radius versatility translates into cleaner finishes, better tolerances, and faster cycle times, making it a dependable choice for engineers, machinists, and shop floors alike.
