Widin’s Carbide Corner Radius End Mill is a precision micro-cutting tool designed for mold and die work. With a compact 0.4 mm diameter, a 0.05 mm corner radius, and a long-neck design, it excels at accurate cornerfiling and deep cavity access in tight mold features.

• Diameter: 0.4 mm cutting diameter for precise micro-milling
• Corner Radius: R0.05 for smooth, accurate fillets and reduced edge wear
• Flutes: 2 flutes provide efficient material removal and a clean surface finish
• Helix Angle: 30° to improve chip evacuation and lower cutting forces
• Neck/Reach: Long-neck design enables access to deep grooves and complex cavities
• Material: Carbide construction delivers hardness, wear resistance, and dimensional stability
• Application: Ideal for mold and die milling, micro-pocketing, and finishing tight radii

This end mill is engineered to deliver dependable performance in delicate mold features. The 2-flute geometry, paired with a 30° helix, helps maintain a smooth cutting action and consistent surface finishes while minimizing tool deflection. The long neck provides extended reach into deep or narrow pockets without compromising rigidity, making it a practical choice for intricate mold and die designs. The corner radius preserves corner integrity during aggressive milling, helping to reduce chipping and prolong tool life, while carbide construction ensures long-lasting sharpness and repeatable results across multiple jobs.
