Description
The Widin Carbide End Mill is a 3 mm diameter, 20 mm overall-length, 2-flute ball-nose milling tool designed for precise contouring, deep grooves, and sloped surfaces. Its tapered neck helps maintain rigidity and reduces vibrations, delivering smooth, stable cuts in challenging profiles.

- Extreme hardness capability with durable coating: Built to cut hard materials up to HRc70, supported by a premium raw material and coating for reliable dry and high-speed cutting and longer tool life.
This end mill is engineered to enhance productivity by delivering dependable performance across demanding materials and geometries, helping you finish parts with fewer passes, less rework, and more consistent surface quality.
