The Widin Carbide Corner Radius End Mill is a precision 4-flute cutter designed for machinists who work with hard materials and detailed internal radii. With a 10 mm cutting diameter and a 0.5 mm corner radius, it delivers reliable, high‑quality milling across demanding applications.

• Diameter: 10 mm — gives a consistent cutting width essential for tight tolerances
• Corner Radius: R0.5 mm — enables smooth, accurate internal corners and fillets
• Flutes: 4-flute design for improved rigidity, efficient chip evacuation, and smoother finishes
• Material: Carbide construction — optimized for hard-to-machine workpieces with wear resistance
• Helix Angle: 45° — enables high-speed cutting with stable feeds and good chip control
• Application Focus: Ideal for hardened steels, die/mold work, and precision pocketing requiring precise corner radii

Designed to tackle high-hardness materials with confidence, this end mill maintains stable performance under demanding milling conditions. The 45° helix and 4-flute geometry reduce chatter and provide consistent material removal, helping you achieve accurate radii, clean edges, and reliable tool life. Use in rigid setups on CNC machines with appropriate lubrication to maximize efficiency and minimize wear. Whether producing precision dies, molds, or complex pockets, the Widin corner radius end mill delivers repeatable results with minimal finishing required.
