Description

Widin Carbide Corner Radius End Mill is a precision cutting tool engineered for stainless steels and exotic alloys. It features a 14 mm cutting diameter, a 0.75 mm corner radius (R0.75), and a 16 mm solid shank, paired with a five-flute, variable-helix design for stable, efficient milling performance.

Designed for demanding workpieces, this end mill uses unequal-index flutes to optimize chip emission and deliver a consistently smooth surface finish. The carbide cutting edge provides excellent wear resistance, helping you achieve longer tool life in hard-to-machine materials. A thoughtfully engineered rake angle tailors cutting action to the material, supporting reliable results across a range of workpieces and conditions.

  • Unequal index flutes for efficient chip emission: Improves chip control and surface finish, reduces clogging, and extends tool life in stainless steels and exotic alloys.
  • High-hardness carbide edge with wear resistance: Maintains sharpness longer for consistent cuts and fewer tool changes in tough materials.
  • Five flutes with a 0.75 mm corner radius and variable helix: Delivers stable cutting, reduces vibration, and preserves critical corners for accurate radii and cleaner pockets.

This combination enables faster, more predictable milling with less finishing work while maintaining tight tolerances. The robust 16 mm shank and optimized geometry minimize deflection and chatter, enabling higher feed rates and longer productive cuts on stainless and exotic alloys. With this end mill, you can expect repeatable, high-quality pocket and corner finishes that reduce downtime and increase overall machining efficiency.
