Widin Carbide Corner Radius End Mill for Stainless & Exotics is built to tackle hard-to-machine materials with confidence. This 16 mm diameter end mill features a 0.5 mm corner radius (R0.5), making it ideal for adding precise, durable fillets in stainless steel and exotic alloys while preserving finish quality and tool life. The combination of 3 flutes, a double-core design, and a variable helix delivers stable cuts and reliable performance in demanding applications.

Excellent chip emission and a smooth workpiece surface finish are achieved by the tool’s unequal index flute arrangement. The double-core construction provides anti-bending strength, helping resist deflection under heavy loads and enabling cleaner pockets and edges.

• Unequal index flutes for chip control: Optimized flute spacing enhances chip evacuation and minimizes built-up edge, leading to smoother cuts and better surface finish in stainless and exotic materials.
• Double-core construction for anti-bending strength: Reinforces rigidity to resist deflection during heavy cuts, delivering consistent pockets and longer tool life.
• Variable helix for versatile performance: Staggered helix geometry reduces vibration and chatter across a range of feeds and materials, improving finish and overall process stability.

This end mill supports professional workflows—from engineers and fabricators to hobbyists—by delivering predictable results, tighter tolerances, and a smoother milling experience in tough alloys.
