Widin Carbide Corner Radius End Mill is a purpose-built tool for mold and die work, offering precise corner radii with a compact 4 mm cutting diameter and a 40 mm overall length. The 2-flute design, 30° helix, and long neck combine to deliver smooth milling and reliable reach for intricate cavities.

• Cutting Diameter: 4 mm
• Overall Length: 40 mm
• Corner Radius: 1 mm (R1)
• Flute Count: 2 flutes
• Helix Angle: 30°
• Shank/Neck: Long neck for extended reach and stability
• Material: Carbide
• Primary Application: Mold & die machining, precision filleting, and deep-pocket milling

This end mill excels at producing clean, accurate radii in mold and die features while maintaining surface quality. The 30° helix reduces cutting forces and promotes efficient chip evacuation, helping you sustain higher material removal rates without sacrificing precision. The long neck provides the necessary reach for deep grooves and complex geometries, enabling consistent results in challenging mold designs. With its carbide construction, this tool offers durability and wear resistance essential for repeatable, high-precision machining.
