Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and exotic alloys. With an 8mm diameter and a 0.5mm corner radius, this 3-flute end mill is engineered to create clean, accurate radii while delivering a smooth surface finish. The unequal index flutes optimize chip control, helping you maintain a steady cut and reduce heat buildup during demanding machining.

Built for reliability, the tool features a double-core design that enhances anti-bending strength, improving stiffness and stability in hard-to-machine materials. The innovative variable-helix geometry further reduces vibration, enabling consistent results across a range of cutting conditions. This combination makes it a trusted choice for precise deburring, radiused pockets, and finishing passes on stainless and exotic metals.

• Unequal index flutes for superior chip emission: Enhances chip evacuation and cooling, helping maintain consistent cutting action and a smoother surface finish.
• Double-core construction for anti-bending strength: Increases rigidity under load, reducing deflection and extending tool life in tough materials.
• Variable helix 3-flute design: Improves stability and finish by reducing chatter, delivering reliable performance across a range of cutting conditions.

This end mill pairs precise corner radii with durable construction, making it a dependable choice for fast, repeatable results. The 8mm diameter and R0.5 corner radius enable clean transitions and accurate features, while the tool’s engineered geometry supports efficient material removal, reduced rework, and consistently high-quality finishes.
