Description
The OSG Carbide 3 Flute End Mill with a corner radius is a precision cutting tool designed for aluminum machining. With a 12 mm diameter and a 1.5 mm corner radius, its three-flute geometry supports clean profiling, milling, and slotting while maintaining stability across cuts.
Designed for a wide range of users—from engineers and machinists to shop-floor technicians and hobbyists—it delivers reliable, high-performance results when precision and efficiency matter.
- Three-flute design for efficient aluminum removal: The three-flute geometry balances chip evacuation and cutting stiffness, enabling steady feeds and consistent material removal in aluminum, which helps maintain dimensional accuracy and a smoother surface finish.
- Corner radius for improved profiling and edge quality: The 1.5 mm corner radius produces defined contours and reduces burrs at corners, enhancing edge quality and part accuracy across complex profiles.
- Carbide construction for long-lasting, reliable performance: A carbide body delivers high hardness and wear resistance, ensuring stable cutting performance and repeatable results across jobs, even with challenging aluminum alloys.
By choosing this end mill, you can streamline aluminum workflows: efficient material removal, improved edge quality, and durable performance translate into faster cycles, fewer tool changes, and consistent part quality—from prototypes to production runs. This tool helps you achieve reliable results with predictable finishes, improving overall efficiency and assembly readiness.
