Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for machinists who need clean radii in deep grooves and sloped surfaces. Built with a tapered neck and a two-flute design, it delivers stable cutting and high-accuracy results in challenging geometries.

- Diameter and length: 2 mm cutting diameter with a 30 mm overall length for reach in tight spaces
- Corner radius: xR0.5 provides precise 0.5 mm rounded corners for consistent radii
- Material: Carbide construction delivers rigidity and wear resistance for long tool life
- Flute count: 2-flute geometry supports efficient chip evacuation and smooth cutting
- Neck design: Tapered neck reduces vibration and chatter, improving stability during aggressive passes
- Applications: Optimized for deep grooves and sloped surfaces where precise radii are essential
- Precision machining: Reinforced corner R capability ensures clean cuts and dimensional accuracy in challenging geometries
This end mill is engineered to minimize tool chatter and deliver a reliable finish, even when working with intricate radii or difficult-to-machine features. Its carbide composition and tapered neck translate into steadier cutting forces, reduced deflection, and better surface quality. The 0.5 mm corner radius enables precise rounding without sacrificing material removal efficiency, making it a strong choice for finishing corners on tight sections and complex pockets.
