Widin Carbide Corner Radius End Mill is a compact, high-precision cutting tool designed for machinists who tackle hard materials. This 3 mm diameter, 20 mm stub-cut end mill features a 1.0 mm corner radius to deliver precise, clean corner finishes and reliable performance in demanding milling tasks.

• Diameter: 3 mm
• Cutting length: 20 mm stub length
• Flutes: 2
• Corner radius: R1.0 (1.0 mm)
• Material: Solid carbide

Designed for high-hardness workpieces, this end mill combines a robust carbide construction with a precisely ground cutting edge to enable efficient material removal, tight tolerances, and smooth radii. The 2-flute configuration provides a balance between rigidity and chip evacuation, making it suitable for slotting, pocketing, and contour milling where stable engagement and predictable finishes matter. The stub-cut length enhances rigidity during deeper passes, reducing tool deflection and improving straightness and accuracy in challenging applications. For best results, pair this tool with appropriate feeds, speeds, and cooling to maintain edge life and surface quality on hardened steels and difficult alloys.
