Widin Carbide Corner Radius End Mill For Mold & Die - 2 Flute Long Neck - 4mm x26mm x R0.3

Designed for mold and die makers, the Widin Carbide Corner Radius End Mill delivers precise radii and clean surface finishes in tight cavities with dependable depth control. Its 2-flute design, 30° helix, and long-neck geometry make it a standout choice for intricate mold work and deep-pocket milling.

• Diameter: 4 mm
• Overall length: 26 mm
• Corner radius: R0.3
• Flutes: 2-flute configuration for smooth cutting action
• Helix angle: 30° for efficient chip evacuation and reduced cutting load
• Shank type: Long neck design providing extended reach and stability
• Material: Carbide, optimized for wear resistance and precision
• Application: Ideal for mold & die milling, deep groove machining, and intricate cavity work

The tool’s 2-flute geometry yields a refined surface finish and predictable engagement, while the 30° helix minimizes cutting forces—helping to extend tool life and improve productivity in demanding molds. The long-neck design enables access to deeper pockets and more complex geometries without sacrificing rigidity, making it well-suited for tight corners and internal radii common in mold and die applications. The 0.3 mm corner radius provides the necessary blend between strong edge retention and smooth radii transitions, reducing stress concentration in finished parts.
