How to select the right tap for aluminum threading?
For aluminum, choose a tap with a polished flute and coolant-through design to reduce built-up edge. A bottoming chamfer suits blind holes, while a plug chamfer works for through holes. Match thread class (e.g., 2B) and tolerance (e.g., H5) to your application requirements.
