Description
The OSG Carbide 4 Flute End Mill Ball Nose TiAlN Coated is a 16mm diameter cutting tool designed for general machining tasks. Its ball nose geometry enables smooth 3D contouring and precise profiling, while the four flutes provide efficient material removal and a quality surface finish.
With a regular-length body and center-cutting capability, it handles plunging and pocketing across common metals and engineered plastics, making it a dependable choice for engineers, fabricators, and hobbyists who require consistent, high-quality results.
- Ball Nose Geometry for Precise 3D Contouring: The rounded tip delivers smooth transitions on complex surfaces, enabling accurate depth control and refined finishes on 3D milling paths.
- TiAlN Coating for Extended Tool Life: The TiAlN layer increases hardness and heat resistance, helping the edge stay sharp longer and resist wear during demanding machining.
- Regular-Length Center-Cutting Design for Versatility: This design supports a wide range of tasks, including plunging into pockets and stable contouring, with consistent rigidity and reduced vibration.
Whether upgrading a shop’s milling lineup or tackling intricate 3D shapes, this 16mm end mill delivers dependable performance and predictable results. The combination of four flutes, ball nose geometry, and TiAlN coating helps you achieve precise contours, smooth finishes, and longer tool life, reducing downtime and boosting productivity across general machining tasks.
