Description

3 Flute Spiral router bits CNC Square Carbide End Mills for Cutting Aluminum Alloys Brass, Bronze, Copper and More

Good for: High power spindle, low speed rotation less than 12000 per minute processing. A series are good for processing rigidity up to 45 HRC, AA series are good for processing rigidity up to 50HRC, 3A are good for processing rigidity up to HRC60.

Key Design Features for Non-Ferrous Metals

Square End / Flat Top: Engineered for precise side milling, slotting, profiling, and producing perfectly flat bottoms on pockets or dadoes.
Up-Cut Spiral Helix: Typically features a high helix angle (around 35° to 38°). The upward shearing action rapidly pulls sticky metal chips up and out of the cut zone, preventing re-cutting of chips which causes immediate tool breakage.
Polished Flutes & Specialized Coatings: High-performance variants are often highly polished or enhanced with specific coatings. Uncoated (bright) carbide works well, but ZrN (Zirconium Nitride) or DLC (Diamond-Like Carbon) coatings drastically decrease friction, preventing aluminum or brass from welding to the cutting edge under intense heat.

Critical Machining Tips for Aluminum, Brass & Bronze

Control Your Feed Rates: High spindle speeds require fast travel speeds to avoid "rubbing." If your CNC moves too slowly, the metal will melt rather than form distinct chips, clogging the flutes instantly.
Use Lubrication/Cooling: While brass and bronze can often be machined dry, aluminum gets highly gummy. Utilizing a mist cooling system, compressed air blast, or a light cutting fluid (like WD-40 or alcohol) drastically improves surface finish and prevents chip welding.
