Widin Carbide Corner Radius End Mill For Mold & Die - 2 Flute Long Neck - 3mm x40mm x R0.2

Designed for mold and die machining, the Widin Carbide Corner Radius End Mill combines a precise 3 mm cutting profile with a 40 mm long neck and a tight 0.2 mm corner radius to tackle deep, intricate cavities with confidence.

• 2 Flutes: Efficient chip evacuation and smooth surface finishes in small-diameter profiles, providing reliable performance on mold and die work.
• 30° Helix Angle: Balanced chip flow and cutting force for steady performance across materials, with common use in general‑purpose carbide end mills.
• Long Neck / Long Reach: Extended reach for deep grooves and undercuts, enhancing stability and enabling profiling in tight mold features.
• Corner Radius: R0.2 design preserves corner accuracy while reducing stress concentration, contributing to longer edge life and smoother finishes.
• Diameter & Length: Ø3 mm cutting diameter with 40 mm overall length (long shank) for versatile deep-pocket access in mold and die components.
• Material: Solid carbide construction for rigidity, wear resistance, and capable performance across common milling applications.
• Application: Optimized for mold and die work, including deep profiling and precise corner radii in cavity corners and slots.

This combination of geometry and reach translates into tangible benefits: you get precise edge quality and smooth surfaces on challenging features, reduced tool deflection in long-reach cuts, and practical, dependable performance for mold and die manufacturing. The 2‑flute configuration with a 30° helix provides efficient material removal and consistent finishes, while the long neck enables access to deeper features without compromising stability. The R0.2 corner radius helps protect corners during aggressive milling, extending tool life and maintaining dimensional accuracy.
