Widin’s Carbide Corner Radius End Mill is a precision micro-milling tool designed for mold and die applications. With a 0.4 mm diameter, a 4 mm long neck, and a precise R0.05 corner radius, it delivers clean fillets and smooth surfaces in tight cavities thanks to its robust carbide construction and engineered geometry.

• Diameter: 0.4 mm for precise detail and tight tolerances in micro features
• Neck Length: Long neck (4 mm) enables extended reach into deep grooves and recessed areas
• Corner Radius: R0.05 to create gentle fillets, reduce stress concentrations, and improve part integrity
• Flutes: 2-flute design provides efficient chip evacuation and stable cutting
• Helix Angle: 30° for smooth cutting action, better processability, and reduced cutting load
• Material: Solid carbide offers high hardness and wear resistance for demanding mold and die work
• Shank Design: Long-neck geometry supports deep cavity machining while maintaining rigidity
• Ideal For: Precision mold and die features, micro-finishes, and finishing passes on small-scale components

This end mill is engineered to deliver consistent surface quality and reliable performance in intricate mold and die geometries. The combination of a small diameter, shallow corner radius, and a long neck enables precise detailing in hard-to-reach areas, while the 2-flute configuration supports efficient material removal and stable tool engagement for repeatable results.
