The Widin Carbide Corner Radius End Mill is a precise, reliable cutting tool designed for machinists who need clean radii and sharp corners on hard materials. With a 4 mm diameter and a 20 mm length of cut in a 4‑flute stub profile, it delivers rigidity and consistent edge definition in compact tooling.

• Diameter: 4 mm
• Flute count: 4-flute design for efficient chip evacuation and stable cutting
• Length of cut: 20 mm (stub-cut geometry to maximize rigidity and reduce deflection)
• Corner radius: R0.3 mm for precise fillets and controlled edge rounding
• Material: Solid carbide for high hardness resistance and long tool life
• Series: ZR704 series, offering reliable corner radii and effective lengths for flexible machining
• Application focus: Tailored for high-hardness workpieces and demanding milling tasks where consistent radii and sharp corners matter

Designed to tackle high-hardness materials with confidence, this end mill maintains dimensional stability under load thanks to its carbide construction and stub-length geometry. The 4-flute configuration balances material removal with finish quality, helping you achieve smooth walls and accurate corners in a single pass. The 0.3 mm corner radius enables precise fillets and controlled edge shaping without sacrificing tool life. Whether you’re pocketing, profiling, or finishing small features, this end mill delivers dependable performance and repeatable results.
