The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and other exotic alloys. With a 13 mm diameter and a 0.3 mm corner radius, this 4-flute end mill is ideal for engineers, manufacturers, and hobbyists who need accurate radii, clean pockets, and reliable performance on CNC and manual mills.

Built for durability, it features carbide construction, a variable helix, and an unequal-index flute arrangement to improve chip evacuation and surface finish—even when cutting hard metals.

• Unequal index 4-flute design: enhances chip emission and delivers a smoother workpiece surface finish by reducing heat buildup and clogging during stainless and exotic-material milling.
• Carbide with high-hardness cutting edge: provides excellent wear resistance and long tool life when cutting hard alloys, helping you get more cycles between tool changes.
• Variable helix for reduced vibration: lowers cutting chatter and stabilizes throughout the cut, producing cleaner holes and better surface quality on challenging materials.

This end mill helps you complete projects more efficiently by delivering consistent radii, smoother finishes, and reliable performance across demanding materials. Its combination of chip-control, wear resistance, and vibration damping supports faster workflows, fewer reworks, and dependable results from prototype runs to production milling.
