Description

The OSG Carbide 4 Flute Variable Lead End Mill is a ball-nose, regular-length carbide tool sized at 5 mm diameter, finished with TiAlN coating for enhanced wear resistance. It’s designed for machinists who work with titanium and a range of general materials, delivering precise contouring, smooth finishes, and dependable performance in demanding applications.

  • Variable lead design for smoother cuts: Reduces chatter and vibration during machining, especially on complex contours, helping maintain tight tolerances and better surface finish.
  • TiAlN coating for extended tool life: High-temperature hardness and wear resistance increase longevity when cutting titanium and other tough materials, reducing tool changes.
  • Ball nose with 4-flute geometry for stable finishes: The ball-end profile produces accurate rounded features while the four flutes provide robust material removal and improved finish consistency.

This end mill helps you boost productivity by delivering reliable, repeatable results in titanium and general-material projects. The combination of vibration reduction, hard-wearing coating, and a steady ball-nose profile translates into fewer passes, less rework, and a smoother surface finish across complex contours and pockets. Trustworthy performance from setup to finished part means you can meet tight tolerances with confidence.
