Description
The Widin Carbide End Mill is a high‑performance ball-nose cutting tool designed for precision contouring and profiling on hard materials. With a stub-cut length and an extended neck, it delivers exceptional reach into deep pockets and tight radii while maintaining control and rigidity. This makes it a versatile choice for engineers, machinists, and hobbyists working on demanding projects.
Built to excel in dry and high‑speed cutting, this end mill features an ALTiN+HH coating and a premium raw material engineered to machine hardened steels up to HRc70. The two-flute design promotes efficient chip evacuation and smooth cutting, helping you achieve consistent finishes even on complex geometries.
- Extended reach for tight pockets: Stub-cut length with an extended neck provides enhanced access to deep features and difficult contours without sacrificing rigidity or precision.
- Hard-material compatibility: ALTiN+HH coating and advanced substrate are optimized for hard steels up to HRc70, delivering reliable wear resistance and longer tool life in dry or high-speed cutting.
- Efficient two-flute design: Two flutes optimize chip evacuation and reduce cutting forces, promoting stable cuts, reduced vibration, and better surface finish on intricate profiles.
Designed for reliable performance across a range of applications, this end mill helps you streamline workflows, cut times, and finish quality. Its combination of extended reach, hardened-material compatibility, and efficient chip management makes it a practical choice for precise contouring, profiling of complex features, and durable operation in tough materials.
