Description
The OSG Carbide 4 Flute End Mill is a square-edge, diamond-coated cutting tool designed for precision work in plastic and graphite.
This regular-length end mill, at 4 mm diameter, features four flutes for efficient material removal, delivering stable, repeatable results across a wide range of projects.
- Diamond-coated longevity: The diamond coating dramatically increases wear resistance, extending tool life in plastic and graphite and helping you avoid frequent tool changes in demanding runs.
- Four-flute rigidity for smooth finishes: Four flutes provide efficient material removal while maintaining stability, reducing chatter and delivering consistent surface quality on plastics and graphite.
- Square-edge precision for clean edges: The square-edge geometry delivers sharp cutting action that yields precise dimensions and burr-free edges, helping you hit tight tolerances with each pass.
With this end mill, you gain durable, reliable performance that supports faster setup, fewer interruptions, and consistently high-quality results across a range of plastic and graphite applications. Its robust carbide core and wear-resistant diamond coating help you complete projects with predictability and confidence, every time.
