Description
The OSG Carbide 3 Flute Centre Cutting Corner Radius End Mill is a precision cutting tool designed for aluminum machining.
With a short length design, 12 mm diameter, three flutes, and a 3 mm corner radius (R3), it delivers stable, efficient material removal and precise edges in tight pockets. This end mill is ideal for machinists, engineers, tradespeople, and hobbyists who require repeatable, high-quality results when working with aluminum components.
- Short length, high rigidity: The compact length minimizes flex and vibration, delivering tighter tolerances and cleaner finishes in confined pockets and real-world shop conditions.
- Three-flute design for efficient aluminum milling: Balanced chip evacuation and rigidity to remove aluminum quickly while maintaining consistent surface quality and tool life.
- Corner radius R3 with Centre-Cutting capability: The 3 mm corner radius supports durable, accurate radii and edge quality, while centre-cutting enables plunge milling and full-depth pockets in aluminum applications.
This end mill is built for reliability and repeatable performance, helping you streamline workflows, reduce rework, and achieve precise, consistent results across aluminum projects. Its combination of rigidity, efficient material removal, and robust edge radii makes it a dependable choice for demanding aluminum machining tasks where accuracy matters.
