Description

Introducing the Widin Carbide End Mill, a compact, precision tool designed for engineers, machinists, and hobbyists tackling intricate profiles. This 2-flute ball-nose cutter features a tapered neck to minimize vibration and chatter, delivering smooth, stable cuts in deep grooves and on sloped surfaces. With a 0.8 mm cutting diameter, 4 mm neck length, and a 0.4 mm shank diameter, it’s built for precision in tight spaces and challenging materials.

  • Tapered neck for smoother cutting: The tapered neck reduces tool vibrations and chatter, especially in deep grooves and on angled surfaces, helping you achieve consistent geometry and better surface finishes.
  • Ball-nose geometry for accurate contours: Ball-shaped tip enables smooth radii and precise contouring across complex shapes, reducing workpiece distortion and improving dimensional accuracy.
  • Coated carbide designed for tough environments: Enhanced coating and new substrate support dry and high-speed cutting on hard materials up to HRc70, delivering longer tool life and reliable performance.

This end mill is built to improve your workflow by delivering stable, repeatable results with fewer passes, less chatter, and dependable performance when machining hardened materials. Whether you’re finishing tight tolerances, pocketing deep features, or contouring complex surfaces, the Widin end mill helps you complete jobs faster, with cleaner finishes and reduced tool wear.
