Up-cut spiral bits help lift chips away from the workpiece, improving chip evacuation and preventing gumming—this is especially important when cutting aluminum。

Single flute bits offer excellent chip clearance for aluminum, while 2–3 flutes can balance clearance and rigidity. Many users prefer single or 2-flute for better results。

Yes—using compressed air or mist helps cool the bit and clear chips efficiently. Many users pair it with a dust collector。

Even trying various cutter types (straight, 2- or 4-flute) doesn’t always eliminate chatter—it often reflects machine rigidity issues more than tool choice

Avoid down-cut or straight-flute bits when machining aluminum; they tend to cause gum buildup and poor chip evacuation.
