The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for machinists tackling hard materials and intricate contours. It features a 12 mm diameter, 4 flutes, and a 1.5 mm corner radius, with a 45° helix that supports high-speed cutting and stable performance.

• Size & corner radius: 12 mm diameter with a 1.5 mm corner radius (R1.5) for smooth fillets and robust edge strength in tight spaces.
• Flute count: 4 flutes for balanced chip evacuation and efficient cutting in hard materials.
• Material: Solid carbide construction delivers superior wear resistance and longer tool life under demanding conditions.
• Helix angle: 45° helix favors fast, stable entry and clean finishes at high feed rates.
• Recommended applications: Optimized for high-hardness workpieces, including contours, pockets, deburring, and precise fillet radii in hardened steels and similar alloys.

Built to translate power into consistent results, this end mill reduces edge chipping and minimizes finishing passes. The combination of a robust corner radius, four-flute design, and a high-helix geometry helps you achieve accurate radii, smooth surface finishes, and productivity gains—even when machining tough materials. Whether you're completing intricate pocketing, contouring, or deburring tasks, this Widin end mill delivers dependable performance and extended tooling life.
