Meet the Widin Carbide Corner Radius End Mill — a precise, versatile cutting tool designed for machinists and engineers who work with hard metals. Its compact stub-cut geometry (3 mm diameter, 8 mm cutting length) and a precise R0.2 corner radius deliver clean radii and sharp corners in tight pockets and along intricate contours.

• Diameter: 3 mm
• Corner Radius: R0.2
• Flute Count: 4-flute configuration for efficient cutting and smooth finishes
• Cutting Length: 8 mm (stub-cut) for rigidity in tight pockets and shallow pockets
• Material: Carbide for enhanced wear resistance on hard workpieces
• End Mill Type: Corner-radius end mill designed to produce precise fillets and clean corners

This end mill is purpose-built to help you achieve accurate radii and sharp corners without sacrificing tool life or finish quality. The 4-flute design supports efficient chip evacuation and stable cutting in hard metals, while the R0.2 radius provides a controlled fillet that reduces stress concentration and improves part reliability. The compact stub-cut geometry minimizes deflection, making it ideal for milling in confined spaces and along tight contours. Whether you’re finishing internal corners, creating precise external radii, or preparing fillets for clean assembly, this Widin end mill delivers repeatable results with every pass.
