Description
Widin Carbide End Mill, 4-flute square-edge, Long Neck, 2.5 mm diameter x 10 mm length. This specialized milling tool is designed to tackle high-hardened materials up to HRc70 with precision and efficiency, making it a dependable choice for engineers, machinists, and hobbyists alike. The long-neck design extends reach into draft-angle features without sacrificing rigidity, helping you avoid interference and maintain accurate geometry on challenging workpieces.
Using a newly developed raw material and an advanced coating, the end mill supports dry cutting and high-speed cutting. This combination enhances heat and wear resistance, preserves sharpness over longer runs, and helps you achieve consistent, high-quality finishes on hardened materials. The ZSLNS20 engineering delivers excellent surface finishes across passes, improving both appearance and dimensional accuracy.
- Long-Neck geometry for draft-angle access: Extended neck length lets you reach into features with draft angles and varying interference lengths, reducing tool interference and enabling clean, accurate cuts on complex geometries.
- Dry cutting and high-speed capability: Built with a newly developed raw material and coating to support dry and high-speed cutting, reducing heat build-up and extending tool life for reliable, efficient production.
- Engineered for hardened materials with superior finish: The ZSLNS20 profile delivers excellent surface finishes on HRc70-grade workpieces, providing smooth tool marks and precise dimensions across passes.
By combining carbide strength, long-neck reach, and a durable coating, this end mill helps you complete jobs faster, with fewer tool changes and consistently high-quality surfaces. It supports repeatable results and a more efficient workflow across demanding materials and applications.
