OSG Carbide 4 Flute End Mill Square Edge Diamond Coated - Regular Length For Plastic & Graphite - 16mm

The OSG Carbide 4 Flute End Mill is a 16 mm diameter, regular-length tool featuring a square-edge profile and a diamond coating. Built for precision work in plastics and graphite, this four-flute cutter pairs robust cutting action with stable, accurate finishes.

Designed for machinists who demand dependable performance over long runs, it helps you achieve consistent results with fewer passes and less wear, making it a reliable choice for both shop floors and home workshops.

• Diamond-coated carbide for extended tool life: The diamond coating provides superior wear resistance, reducing edge dulling and minimizing routine tool changes, so you can run longer between re-sharpening or replacements.
• 4-flute design for fast, stable cutting: Four flutes optimize material removal and chip evacuation while maintaining rigidity, resulting in smoother cuts in plastic and graphite and fewer deflections.
• Square-edge geometry for clean, accurate finishes: The square-edge profile delivers precise corners and shoulders, helping maintain tight tolerances and reducing downstream finishing requirements.

This end mill helps you streamline production, deliver repeatable, high-quality parts, and reduce downtime by combining a long-wearing coating with a geometry tuned for plastics and graphite. Whether you're prototyping, producing small batches, or performing high-precision work, this tool supports reliable performance and confident results across your workflow.
