Description

The Widin Carbide End Mill is a precision 2-flute ball-nose milling tool designed for intricate profiling and tight-radius work. Its tapered neck reduces vibration and chatter, delivering stable cuts in deep grooves and along sloped surfaces.

With a cutting diameter of 1.8 mm, 16 mm overall length, and a 0.4 Ø shank, this micro end mill fits tight pockets and fine-detail applications while maintaining rigidity during aggressive passes. Built to handle tough conditions, it’s engineered to machine hardened materials up to HRc70 and features a newly developed raw material and coating that support dry and high-speed cutting.

  • Tapered neck for stable, low-vibration cutting: minimizes chatter in deep or angled features, helping you achieve consistent finishes and longer tool life.
  • Ball-nose geometry for smooth contours: enables precise, curved finishing passes on complex 3D shapes with predictable radii and surface quality.
  • High-hardness capability with durable coating: designed to cut hard materials up to HRc70 and excel in dry or high-speed cutting, delivering reliable wear resistance and repeatable results.

This end mill supports efficient workflow by delivering accurate profiles with fewer passes, reducing setup time and tool changes. The tapered neck and ball-nose design help you navigate tight features and depth without sacrificing stability, while the hardened-core construction and coating guard against wear in demanding applications—from prototyping to production—so you can trust it to perform job after job.
