Description

The Widin Carbide Radius End Mill is a versatile 4-flute cutting tool designed for contouring, profiling, and slotting in a wide range of materials. With a cutting diameter of 12 mm, a 1 mm radius, and a 12 mm shank, this end mill delivers precise radii and clean edges across demanding machining tasks.

Constructed from carbide for durability and wear resistance, it combines a radius-end geometry with a 45° helix to promote efficient chip evacuation, reduce cutting forces, and extend tool life. The 4-flute design enhances material removal while maintaining a smooth finish, even on tougher workpieces.

  • Radius End Geometry for Smooth Contouring: The rounded tip enables precise profiling, contouring, and slotting with consistent radii and clean edge quality.
  • 4-Flute Design for Efficient Cutting: Four flutes provide robust material removal and improved chip evacuation, helping maintain steady cutting and a longer tool life.
  • 45° Helix for Stability and Reduced Deflection: The angled flute geometry increases rigidity during cuts, minimizes deflection, and supports a stable, high-quality surface finish.

This end mill is engineered to deliver reliable, repeatable results in demanding machining operations, helping you complete complex parts with confidence while minimizing downtime and rework.
