Description
The OSG Carbide 3 Flute End Mill is a square-edge, 4 mm diameter tool designed specifically for aluminum machining.
With a three-flute configuration, it efficiently removes material while maintaining stable, precise cuts. This end mill is an excellent choice for machinists working with aluminum, whether you're milling, profiling, or slotting, to achieve consistent results in both prototypes and production parts.
- Three-flute design for efficient aluminum removal: The three-flute geometry balances chip evacuation and rigidity, helping you cut faster with smoother finishes and less clogging in aluminum applications.
- Square-edge geometry for clean, accurate cuts: The square edge delivers sharp, burr-free edges on profiles, slots, and contours, improving part quality and reducing the need for secondary finishing.
- Durable carbide for long tool life: Premium carbide substrate and robust construction resist wear at typical aluminum cutting speeds, delivering consistent performance and fewer tool changes.
Using this end mill simplifies your workflow by delivering predictable, repeatable results across milling, profiling, and slotting tasks. Its geometry and material choice support smooth operation, reduced downtime, and tighter tolerances, helping you finish aluminum projects faster with confidence and fewer interruptions.
