Description

Widin Carbide End Mill is a precision cutting tool designed for challenging, high-hardness materials. This 2 mm diameter, 16 mm length end mill features four flutes and a square-edge profile to deliver consistent geometry and smooth finishes in tight workspaces.

Its long-neck design provides the necessary clearance for draft-angle features, helping you avoid interference and maintain productive engagement when machining complex geometries. Built for dry cutting and high-speed operation, the tool uses a newly developed raw material and the advanced ZSLNS20 coating to boost heat resistance and wear life, delivering reliable performance on hardened materials up to HRc70.

  • Long-Neck Design for Draft-Angle Accessibility: Extended neck clearance lets you reach deep pockets and complex features caused by draft angles, reducing interference and enabling consistent cutting without repositioning.
  • Dry-Cutting Ready with ZSLNS20-Coated Carbide: Optimized for dry and high-speed cutting, the advanced coating and carbide substrate enhance heat and wear resistance for longer tool life and stable performance under demanding feeds and speeds.
  • Four-Flute Square Edge for Finishes: Four cutting edges with a square-edge geometry produce clean contours and excellent surface finishes on hard materials, helping you achieve precise parts with fewer finishing passes.

Designed to tackle tough materials with confidence, this end mill improves workflow by enabling efficient material removal, reliable finishes, and longer tool life. Its robust construction and coating deliver consistent results across production runs, making it a dependable choice for engineers, machinists, and hobbyists working on demanding projects.
