Widin Carbide Corner Radius End Mill for Mold & Die is a precision micro-cutting tool designed for intricate mold and die work. With a tiny 0.4 mm diameter and a long-neck construction, it reaches tight pockets and deep grooves while delivering clean, accurate radii.

• Diameter: 0.4 mm
• Cutting Length: 3 mm
• Corner Radius: R0.05
• Flutes: 2
• Helix Angle: 30°
• Shank/Reach: Long neck design for extended reach into deep features
• Material: Carbide
• Application: Micro-finishing, precise grooving, radii and contouring in mold and die work

This end mill combines a two-flute geometry with a 30° helix to optimize material removal and reduce cutting forces, helping you achieve smoother finishes with consistent tool life. The long neck offers stable access to deep features, while the tight R0.05 corner radius preserves sharp, defined corners essential for accurate molds and dies. Ideal for high-precision micro-machining tasks where control, repeatability, and fine detail matter.
