Polished Tungsten Carbide Long Neck Micro End Mill (For Aluminum)

Achieve superior surface finishes in deep cavities and rib processing with our specialized Long Neck Micro End Mills for Aluminum.

Standard micro end mills often fail in deep slots due to shank rubbing or chip packing. Our "Deep Reach" series features a reduced neck diameter for clearance and a high-polish flute specifically engineered for non-ferrous metals.

Key Features & SEO Benefits

Anti-Stick Polished Flutes: Unlike steel cutters, these tools feature a mirror-polished finish (or optional DLC coating) to eliminate material adhesion (built-up edge) when machining gummy materials like Aluminum 6061/7075.

Deep Reach (Rib Processing): The relieved neck allows the tool to reach deep into molds or heat sinks without the shank rubbing against the walls, preventing vibration and marks.

Optimized for Chip Evacuation: The 2-flute geometry with a high helix angle ensures rapid chip removal, which is critical when milling deep pockets to prevent tool breakage.

Precision 4mm Shank: Standard h6 tolerance 4mm shank ensures high rigidity and minimizes run-out, essential for micro-machining accuracy.

Applications

Electronics (3C): Deep slots in aluminum phone casings and laptop frames.

Heat Sinks: Machining deep, thin fins in aluminum and copper.

Mold Making: Processing electrode ribs for EDM or direct aluminum mold milling.

Why Choose Our Long Neck Cutters?

Precision manufacturing ensures that the concentricity between the shank and the cutting edge is within 0.005mm. This minimizes run-out, which is the #1 cause of tool breakage when using long-reach micro tools.

Custom sizes and DLC coatings are available upon request. Contact us for a quote!
