Product Specifications:
This 3‑flute solid carbide end mill is specifically designed for high‑gloss finishing of aluminum alloys in deep cavities. The extra‑long 75mm overall length provides extended reach for deep pocket milling, while the 4mm cutting diameter allows intricate detail work and fine finishing. Mirror‑polished flutes eliminate aluminum adhesion (built‑up edge), ensuring a consistent mirror‑like surface finish on LED housings, automotive trim, and cosmetic aluminum parts.
The 45° high helix angle actively lifts chips upward, preventing recutting in deep slots. Unlike standard 2‑flute aluminum end mills, this 3‑flute design offers better surface finish while maintaining chip clearance. Ideal for CNC machining of 6061, 7075, and cast aluminum alloys. For deeper cavities (> 3× diameter), the extra length provides the necessary reach without excessive tool overhang.
Uncoated but polished, this tool outperforms coated end mills in non‑ferrous materials. Custom lengths up to 100mm and alternative coatings (DLC, ZrN) available for OEM orders. Upgrade your aluminum finishing with this precision‑ground 3‑flute end mill – experience burr‑free edges and mirror‑bright surfaces.
