Widin Carbide Corner Radius End Mill For Mold & Die - 2 Flute Long Neck - 4mm x20mm x R0.3

Engineered for precision mold and die work, this Widin carbide corner radius end mill delivers clean surfaces and reliable reach for intricate cavities. With a compact 4 mm diameter and a long-neck design, it's built to access deep pockets and tight grooves while maintaining rigidity and consistent cutting performance.

• Diameter: 4 mm
• Flute count: 2 flutes
• Length of cut: 20 mm
• Corner radius: R0.3
• Material: Carbide
• Helix angle: 30°
• Shank: Long neck / long shank design for deep grooves
• Application: Mold and die machining, precision pocketing and deep groove work

The combination of a 30° helix and two flutes minimizes cutting resistance, allowing steady feeds and reducing workpiece deflection for smooth, accurate surface finishes. The long-neck geometry provides extended reach to engage deep features without sacrificing stability, making it well-suited for complex mold inserts and die cavities. Carbide delivers wear resistance and edge retention, helping you maintain tight tolerances over many cycles. The 0.3 mm corner radius balances strength with part geometry, reducing the risk of corner chipping while still delivering sharp, accurate corners where required.
