Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool engineered for tough metals. With a 12 mm diameter and a 0.75 mm corner radius, this 5‑flute end mill features a variable helix that improves chip evacuation and delivers a smooth, uniform surface finish on challenging alloys.

Designed for stainless steels and other exotic materials, it combines a high-hardness cutting edge with unequal index flutes to resist wear and maintain sharpness across long runs. The rake-angle geometry is carefully optimized to suit the workpiece characteristics, helping you achieve reliable cuts and repeatable results.

• Unequal index flutes for improved chip emission: The staggered flute arrangement reduces chip buildup and heat, helping you maintain steady feeds and a cleaner finish on stainless and exotic metals.
• 5-flute carbide with variable helix for durable cutting: More flutes provide rigidity and strength, while the variable helix enhances cutting stability and wear resistance in tough alloys.
• Corner radius R0.75 with optimized rake angle: The 0.75 mm corner radius supports strong fillets for durable parts, and the rake angle is tuned to deliver consistent, smooth machining across various workpieces.

The Widin Corner Radius End Mill helps you achieve cleaner corners, smoother finishes, and longer tool life in demanding materials. With efficient chip evacuation and a durable carbide edge, you can maintain steady productivity, reduce finishing passes, and rely on consistent, high-quality results across a range of stainless and exotic alloys.
