2-Flute End Mills for Aluminum
High Precision Tungsten Carbide Micro End Mill - 2 Flute for Aluminum & Non-Ferrous Metals
Premium sub-micron carbide micro end mills specifically designed for high-speed machining of aluminum and copper. Features mirror-polished flutes and sharp cutting edges to prevent chip buildup and ensure a burr-free, mirror-like finish.
Product Overview
Our Tungsten Carbide Micro End Mills for Aluminum are engineered for extreme precision in miniature CNC machining. Designed for industries like electronics, medical devices, and aerospace, these tools feature mirror-polished flutes and a razor-sharp 2-flute geometry.
The large chip evacuation space is specifically optimized to handle the "sticky" nature of aluminum and non-ferrous alloys, preventing material melting and built-up edge (BUE) even at high RPMs.
Technical Highlights
- Mirror Polished Flutes: Exceptionally smooth flute surfaces reduce friction, allowing aluminum chips to slide out rapidly without sticking.
- Ultra-Sharp Cutting Edge: Specifically ground to achieve a burr-free finish and superior surface quality on soft metals like Aluminum (6061/7075), Copper, and Brass.
- Reinforced 4mm Shank: All diameters feature a standard 4.0mm shank for maximum rigidity, reducing tool deflection and preventing breakage in micro-machining.
- 0.01mm Increments: Available in a full range from φ0.20 to φ0.96 to meet the most demanding tolerance requirements.
