Meet the Widin carbide corner radius end mill—designed for machinists, mold makers, and precision fabricators who tackle hard metals and deep grooves. The 4-flute, long-shank geometry with a precise R0.2 corner radius delivers consistent fillets and clean finishes in difficult workpieces.

- Diameter: 4 mm cutting diameter for precise material removal in small slots and pockets.
- Corner Radius: R0.2 corner radius to create smooth internal corners and consistent fillets.
- Flutes: 4-flute configuration for efficient chip evacuation and stable cutting at higher speeds.
- Material: Solid carbide for high hardness resistance, rigidity, and longer tool life.
- Shank: Long shank design provides extended reach for deep grooves, pockets, and undercut features.
- Cutting Edge Design: Optimized geometry reduces vibration and improves surface finish on tough materials.
This end mill is ideal for operators working with hard-to-cut materials and applications that demand deep access—such as deep groove milling, pocketing, and contour finishing. The long shank enhances reach without sacrificing rigidity, while the carbide construction maintains accuracy and durability over extended cutting sessions. Expect precise radii, smooth tool paths, and dependable performance in demanding machining tasks.
