Meet the Widin Carbide Corner Radius End Mill for Mold & Die. Designed for professionals working on molds, dies, and precision cavities, this 4-flute end mill features a tapered neck and a corner radius of R0.3. With a 4 mm cutting diameter and 70 mm overall length, it delivers stable, accurate cuts across a range of deep groove applications. The tapered effective length boosts rigidity, helping you maintain tight tolerances and smooth surface finishes. It’s available in multiple specifications so you can pick the ideal length for your machining task.

• 4-Flute configuration for smooth, stable cutting: The four cutting edges share the load, reducing chatter and producing cleaner surfaces while extending tool life in tough materials.
• Tapered neck for enhanced rigidity: The neck tapers to increase stiffness where it counts, improving accuracy in deep grooves and reducing deflection during heavy cuts.
• Corner radius of R0.3 for precise mold/die corners: Maintains crisp radii on molded features, minimizes tool marks, and delivers consistent finishes across cavities.

With Widin's corner radius end mill, you gain reliable performance that supports efficient workflows, fewer tool changes, and consistent results across production runs. The combination of carbide hardness, 4-flute geometry, and a tapered neck translates to longer tool life, reduced downtime, and superior surface finishes on molds and dies — helping you achieve tight tolerances and repeatable quality in every part.
