High Polish Solid Carbide Ball Nose End Mill (For Aluminum)
Master deep 3D machining in non-ferrous materials with our Extra Long Aluminum Ball Nose Series.
Unlike coated steel cutters that cause aluminum to stick and weld, these tools feature a Mirror-Polished (Uncoated) Finish and a specialized high-helix geometry. This ensures chips slide effortlessly out of deep cavities, leaving a smooth surface finish on Aluminum, Brass, Copper, and Plastics.
With Overall Lengths available up to 150mm, this series is the ultimate solution for machining deep impellers, prototypes, and molds.
Key Features & SEO Benefits
- Mirror-Polished Flutes: Eliminates friction and prevents the "built-up edge" (aluminum melting onto the tool), which is the #1 cause of tool breakage in deep aluminum milling.
- Extra Long Reach (Up to 150mm): We stock hard-to-find lengths (75mm, 100mm, 150mm), allowing you to reach the bottom of deep pockets without dangerous tool stick-out from the collet.
- High Helix Angle (45°): Designed to pull soft, gummy chips up and out of the cutting zone rapidly.
- 2-Flute Design: Large chip gullets provide maximum space for swarf evacuation, essential for heavy roughing and contouring.
Applications
- Aerospace & Automotive: Machining aluminum impellers and intake manifolds.
- Deep Mold Making: Finishing deep cavities in aluminum proto-molds (6061/7075).
- 3D Carving: Large-scale relief carving in wood, acrylic, and plastic.

Why Choose Polished Tools for Deep Reach?
When machining deep features, coolant often struggles to reach the cutting tip. A polished surface is your best defense, as it naturally reduces heat and friction, allowing the tool to perform even when coolant access is limited.
