Description
The OSG Carbide 3 Flute End Mill with a corner radius is a precision cutting tool designed specifically for aluminum. With an 8 mm diameter and a corner radius of 1.25 mm, it delivers reliable material removal, clean edges, and stable performance across milling, profiling, and slotting tasks.
Ideal for machinists, engineers, tradespeople, hobbyists, and anyone working with aluminum, this end mill combines versatility with dependable results. Its three-flute geometry supports efficient cutting and smooth finishes, making it a go-to choice for consistent quality in aluminum components.
- Three-Flute Design for Efficient Aluminum Cutting: The balanced flute count provides rigidity and effective chip evacuation, enabling higher feed rates and smoother surfaces when machining aluminum.
- R1.25 Corner Radius for Precise Finishing: The corner radius preserves edge strength while delivering accurate radii in pockets and contours, reducing corner rounding and improving fit and appearance.
- Carbide Durability for Long Tool Life: Hardened carbide delivers exceptional wear resistance and repeatable results, even at higher speeds and with demanding aluminum alloys.
This end mill helps you complete aluminum projects faster, with fewer passes and less rework, while maintaining tight tolerances and a clean, professional finish. It’s a reliable, high-performance choice for shops and hobbyists aiming for precise, repeatable results.
