Widin Carbide Corner Radius End Mill For Stainless & Exotics - 4 Flute Variable Helix - 3mm x R0.1

The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and exotic alloys. With a 3 mm diameter and a 0.1 mm corner radius, this 4-flute end mill uses a variable helix to deliver steady, controlled cutting and clean pocket corners.

Its unequal index flute geometry promotes efficient chip evacuation and a smooth workpiece surface, while the hard carbide cutting edge provides strong wear resistance for longer tool life in demanding metals.

• Unequal index flute design for superior chip control: Excellent chip emission and smoother surface finish when cutting stainless and exotic materials, reducing built-up edge and improving part quality.
• 4-flute carbide construction with variable helix for durable, stable cutting: Reduces vibration, distributes cutting forces, and delivers consistent finishes across tough alloys for longer tool life.
• 3 mm diameter with 0.1 mm corner radius for precise details: Enables clean, accurate corners and radii in tight features, improving accuracy and reducing post-machining work.

In daily machining, this end mill helps you finish parts faster with fewer passes and fewer tool changes, while delivering smoother surfaces and reliable wear performance. It’s a dependable choice for shops and hobbyists who value consistent results, predictable performance, and long tool life when working with stainless and exotic materials.
