Widin Carbide Corner Radius End Mill for Mold & Die is a high-performance four-flute carbide tool engineered for demanding mold and die machining. With a 4 mm cutting diameter, a 14 mm length, and a corner radius of R1, it delivers precise fillets and smooth finishes on complex cavities. Its long-shank design provides the reach and stability needed for deep-pocket work and intricate profiles.

The tool combines a variable index geometry with efficient chip evacuation to maintain steady cutting forces, minimize vibration, and improve surface quality—helping moldmakers and die-makers finish parts faster and with fewer passes.

• Variable Index Geometry for Smoother Cutting and Better Finish: Staggered cutting edges reduce peak loads and chatter, while promoting efficient chip evacuation for cleaner surfaces and longer tool life.
• Corner Radius Options for Precise Mold Features: Multiple corner radii let you reproduce accurate fillets and mating surfaces, improving fit, finish, and consistency across molds and dies.
• Long Shank for Deep Groove Access: The extended shank enables reach into deep cavities and tight pockets with enhanced stability and reduced tool deflection.

This end mill is designed to empower a wide range of users—from engineers and buyers to machinists and hobbyists—by delivering reliable performance, precise geometries, and a versatile reach that helps you achieve consistent results with fewer tool changes and less rework.
