Description

The Widin Carbide End Mill is a precision four-flute square-edge cutting tool designed to tackle very hard materials with confidence. With a 5 mm cutting diameter and a 16 mm length, this long-neck design delivers the reach and rigidity needed for challenging applications up to HRc70, helping you finish parts to tight tolerances in fewer passes.

Built for reliability in demanding environments, the tool’s long neck provides the necessary clearance for draft-angle features and undercuts, reducing interference and improving consistency when machining complex workpieces. A newly developed raw material and an advanced coating boost heat resistance and wear performance, enabling smoother dry and high-speed cutting.

  • 4‑Flute Square‑Edge Geometry: Delivers stable cutting with efficient chip evacuation, helping you achieve consistent finishes on hard materials and reduce cycle times.
  • Long Neck for Draft-Angle Features: Extended neck length provides extra reach and clearance, preventing interference on parts with draft angles and undercuts.
  • Dry Cutting and High‑Speed Readiness: Enhanced coating and carbide composition enable true dry cutting and higher cutting speeds, delivering better heat resistance, longer tool life, and superior surface finishes.

Designed to increase productivity, the Widin End Mill helps you complete tough jobs with greater accuracy, fewer tool changes, and dependable performance across a range of demanding applications. It pairs robust construction with precise finishes, giving you the confidence to tackle challenging materials and complex geometries in your shop.
