How to select the correct OSG tap for aluminum threading?

For aluminum, choose a tap with a polished flute or coating like V coating to reduce built-up edge. A bottoming chamfer suits blind holes, while a plug chamfer works for through holes. Match thread size and tolerance (e.g., H3 / 2B-3B) to your application.
