Description

The Widin Carbide End Mill is a 3-flute ball-nose milling tool crafted for precision contouring and finishing. With a 3 mm diameter and 16 mm length, this carbide end mill is well-suited for engineers, machinists, hobbyists, and tradespeople tackling complex profiles, grooves, and sloped surfaces. The tapered neck design reduces tool vibration and chatter, delivering smoother cuts and improved dimensional accuracy on challenging parts.

  • Tapered Neck for Stability and Precision: The tapered neck minimizes vibration and chatter, enabling smooth, stable cutting in deep grooves and on inclined surfaces for more consistent geometry and fewer finishing passes.
  • Ball Nose, 3-Flute Geometry for Contoured Surfaces: Ball-nose geometry delivers true rounded profiles and excellent surface finish on complex contours, making it ideal for pockets, fillets, and sculpted features.
  • Advanced Material and Coating for Dry/High-Speed Cutting: A newly developed substrate and coating support dry cutting and high-speed operations, delivering longer tool life and reliable performance even in demanding applications, including hard materials up to HRc70.

The end mill’s effective neck length, aligned with the rake angle, provides real flexibility across a variety of machining scenarios, from deep groove operations to sloped surface milling. Built for reliability in tough environments, it enables efficient workflows, reduced downtime, and consistent results that professionals can trust in both production settings and precision work.
