The Widin Carbide Corner Radius End Mill for Mold & Die is a compact, high-precision cutting tool designed to create accurate corner radii on sloped surfaces and complex mold profiles. Its 4-flute tapered neck delivers stable, controlled cuts across varying taper angles, making it ideal for mold and die applications where precise fillets and smooth transitions matter.

Crafted from carbide for exceptional wear resistance and long tool life, this end mill combines rigidity with efficient chip control. The 1.5 mm diameter and 20 mm length provide access to tight features, while the R0.3 corner radius yields consistent, accurate fillets on delicate surfaces.

• Tapered neck for enhanced stability: The tapered neck design reduces bending and deflection when cutting angled surfaces, delivering straighter, more predictable cuts on complex mold geometries.
• Precise corner radius of R0.3 for smooth fillets: Produces consistent corner radii on sloped profiles, enabling accurate mating surfaces and reducing the need for post-process finishing.
• 4-flute design with efficient chip evacuation: Four flutes provide steady material removal and excellent chip clearance, improving surface finish and reducing clogging during high-feed milling.

This end mill is built to help you complete intricate mold and die features with confidence. The combination of carbide hardness, tapered neck rigidity, and precise corner radii translates to reliable performance, reduced downtime, and repeatable results across production runs. Whether you're prototyping complex geometries or performing high-precision finishing, this tool supports clean finishes, tight tolerances, and faster cycle times.
