For aluminum, choose a tap with a polished flute or coating to reduce chip adhesion. The OSG V coated powdered metal tap resists wear in abrasive aluminum alloys. A bottoming chamfer is best for blind holes, while a plug chamfer suits through-holes. Always match thread size and tolerance (e.g., H3 / 2B-3B) to your application.
