Widin Carbide Corner Radius End Mill For Mold & Die - 2 Flute Long Neck - 4mm x14mm x R0.1

Widin's Carbide Corner Radius End Mill is a precision cutting tool tailored for mold and die work. With a 4 mm diameter, 14 mm cutting length, and a 0.1 mm corner radius, it delivers clean internal corners and smooth pockets, while the long neck provides extended reach for challenging cavities.

• Diameter: 4 mm
• Cutting length: 14 mm
• Corner radius: R0.1 mm
• Flutes: 2
• Material: Solid carbide
• Helix angle: 30°
• Shank / neck: Long neck for deep groove access and stability
• Ideal for: Mold and die applications, precision pockets, and narrow cavities

The two-flute geometry paired with a 30° helix reduces cutting load and promotes efficient chip evacuation, enabling steady material removal and a smoother surface finish. The 0.1 mm corner radius is optimized to create precise, consistent radii in mold features without introducing excessive tool stress, helping maintain dimensional accuracy over repeated cycles. The long neck design extends reach into deep grooves and complex geometry, improving control and reducing deflection during heavy milling steps. Built from carbide, this end mill combines hardness and wear resistance to support repeatable performance in demanding mold and die manufacturing environments.
