Meet the Widin Carbide Corner Radius End Mill—a precision cutting tool designed for machinists tackling high-hardness workpieces. With a 12 mm diameter, a 0.2 mm corner radius (R0.2), a 2-flute design, and a long shank, it’s engineered for deep groove machining and extended reach.

• Diameter and corner radius: 12 mm diameter with a 0.2 mm corner radius (R0.2) for controlled edge engagement and precise corner finishing.
• Flute count: 2-flute geometry for balanced rigidity and efficient chip evacuation during cutting.
• Material: Carbide construction delivers high hardness resistance and extended tool life when machining tough materials.
• Shank: Long shank design provides extra reach for deep grooves, recesses, and tight access areas.
• Edge geometry: Corner radius engineered to maintain strength when cutting high-hardness workpieces, reducing chatter and deflection.
• Ideal applications: Perfect for deep groove machining, pocketing, and slotting in hard metals where precision and reach matter.

This end mill is built to preserve dimensional accuracy and surface quality on challenging materials. The combination of carbide durability, a purposeful corner radius, and a long shank enables consistent cuts, fewer tool changes, and reliable performance in confined or deep-access tasks. Use with appropriate spindle speeds and coolant to maximize tool life and finish when working with high-hardness substrates.
