Description
Designed for precision machining in plastic and graphite, this 2 mm diameter, regular-length OSG Carbide 4-Flute End Mill features a square-edge geometry for clean, accurate profiles. The diamond coating boosts wear resistance, extending tool life and reducing downtime on demanding jobs.
- Diamond coating for longer tool life: The diamond-enhanced edge minimizes wear and friction, delivering extended tool life and fewer tool changes in plastic and graphite workpieces.
- Square-edge geometry for precise cuts: The sharp, square edge produces crisp corners and smooth walls, reducing chipping and the need for rework on delicate materials.
- Four-flute design for fast, stable cutting: Four flutes enable efficient material removal with balanced cutting action, delivering consistent finishes and reduced vibration over longer runs.
This end mill helps you achieve repeatable, high-quality results with less downtime. The combination of a robust diamond coating and precise square-edge geometry supports tight tolerances, clean edge quality, and reliable performance across production runs and prototypes alike—particularly when working with plastic and graphite materials.
