The Widin Carbide Corner Radius End Mill is a precision cutting tool for machinists tackling tight radii on hard materials. With a 3 mm diameter, 20 mm cutting length, and a small R0.2 corner radius, this 4‑flute stub-cut end mill delivers accurate, repeatable results in compact CNC setups.

• Diameter: 3 mm
• Cutting Length: 20 mm
• Corner Radius: R0.2
• Flutes: 4-flute design
• Cutting Style: Stub-cut length for rigidity and precise starts
• Material: Solid carbide for high-hardness workpieces and wear resistance

This end mill is engineered to handle high-hardness workpieces, delivering clean radii and sharp corners while maintaining dimensional accuracy across passes. The four-flute geometry improves chip evacuation and reduces cutting forces, enabling smoother cuts and more stable tool life in challenging materials. Ideal for finishing pockets, fillets, and tight inside corners on compact parts, it helps you achieve precise details with fewer deburring steps.
