Description

Widin Carbide End Mill For Stainless & Exotics - 4 Flute Variable Helix LongShank - Square Edge - 16mm is designed for professionals tackling stainless steels and exotic alloys. The 16mm diameter, 4-flute configuration with a variable helix and a long shank provides reliable cutting performance and extended reach for challenging milling tasks.

With a square edge and an optimized flute arrangement, this end mill delivers efficient chip emission and a smooth workpiece surface finish, even on tough materials. The cutting edge combines high hardness with excellent wear resistance, helping it stand up to demanding use over time.

  • Unequal index flute geometry: Improves chip emission and delivers a smoother surface finish on stainless and exotic materials by managing chip load across flutes.
  • High-hardness carbide edge: Provides exceptional wear resistance and long tool life when cutting tough materials like stainless steels and exotic alloys.
  • Corner chamfer on end face: Reduces cutting edge chipping, helping maintain sharpness and extend tool life in demanding milling operations.

This end mill supports precise, dependable milling with extended reach and stable performance, helping you complete jobs with consistent results and fewer rework episodes. Its geometry and design are tailored to deliver reliable performance on challenging materials, making it a trustworthy choice for professional workshops and serious hobbyists alike.
