Widin Carbide Corner Radius End Mill is a precision cutting tool for machinists and engineers working with hard materials. With a 3 mm diameter, 8 mm cutting length, and a 0.3 mm corner radius, this 4‑flute stub‑cut end mill delivers clean corners and reliable performance across demanding milling tasks.

• Diameter: 3 mm
• Cutting length: 8 mm (stub-cut) for improved rigidity and control
• Flutes: 4-flute design for efficient chip evacuation and smooth cutting
• Corner radius: R0.3 mm for precise fillets and sharp edges
• Material: Carbide for exceptional wear resistance and heat tolerance
• Versatility: Ideal for producing both sharp corners and smooth radii on hard workpieces
• ZR704 compatibility: Provides extended choice with various corner radii sizes and effective lengths to meet specific machining needs

This end mill is engineered to tackle high-hardness workpieces with confidence, delivering consistent results and longer tool life. The stub-cut geometry reduces tool deflection at higher feeds, helping you achieve repeatable, tight radii and precise corners in hardened steels and similar materials. Whether you’re roughing pockets or finishing delicate fillets, this tool offers reliable performance and flexibility across a range of demanding precision applications.
