Description

Widin Carbide End Mill is a 3-flute ball-nose milling tool designed for precise contouring and challenging materials. With a 2 mm cutting diameter and a 16 mm length, it excels in small-radius profiling, deep grooves, and sloped surfaces, delivering stable cuts and consistent results. The tapered neck reduces vibration and chatter, helping maintain accuracy across passes and across complex geometries.

  • Tapered Neck for Reduced Vibration: The tapered neck minimizes tool whip and chatter, enabling smoother entry and stable cutting in deep pockets and angled surfaces for better dimensional control.
  • Ball Nose Geometry for Smooth Contours: The rounded tip delivers natural radii on complex 3D shapes, producing refined finishes with fewer post-processing steps.
  • Durable Carbide with Advanced Coating: Built to handle hard materials up to HRc70, the new raw material and coating support reliable dry and high-speed cutting, extending tool life in demanding environments.

This end mill helps you work confidently on tough alloys and intricate geometries, improving workflow efficiency, reducing downtime, and delivering repeatable, high-quality finishes. Its blend of neck design, ball-nose geometry, and rugged coating makes it a dependable choice for precise pocketing, contouring, and finishing tasks in professional and hobbyist shops alike.
