For aluminum threading, choose an interrupted-thread tap like the WIDIA GTD 16104 to prevent chip clogging. Verify the thread size (1/8"-27 NPTF), chamfer type (plug for through holes), and flute count (5 flutes for chip evacuation). Always match the tap to the material hardness and thread class (H3/3B) for proper fit.
