Widin Carbide Corner Radius End Mill For Mold & Die - 2 Flute Long Neck - 0.4mm x4mm x R1

Widin Carbide Corner Radius End Mill for Mold & Die is a precision micro-milling tool designed for tight corners and intricate mold features. With a 2-flute, long-neck design, it delivers clean surfaces and reliable performance on small-diameter detail work.

• Diameter: 0.4 mm
• Flutes: 2-flute configuration for rigidity and smooth cutting
• Helix angle: 30° for efficient chip evacuation and reduced cutting load
• Corner radius: R1 for defined edge profiles on tight corners
• Neck / Reach: Long-neck design enabling access to deep grooves and recessed areas
• Material: Carbide for hardness, wear resistance, and long tool life
• Intended use: Mold and die machining, micro-milling, and precision finishing

Designed for precision and consistency, this end mill helps you achieve smooth surface finishes on micro-features while maintaining dimensional accuracy. The 2-flute geometry minimizes deflection, while the 30° helix provides a balanced cut with efficient chip removal. The long-neck reach allows you to access deep cavities without sacrificing stability, making it ideal for intricate mold and die designs. With carbide construction, you gain wear resistance and extended tool life in demanding materials, delivering repeatable results across multiple jobs.
