How to select the correct OSG Straight Flute Tap for aluminum?
For aluminum, choose a tap with a bottoming chamfer if threading blind holes, or a plug chamfer for through holes. Carbide material provides longer tool life. Ensure the thread size (e.g., 7/16"-20 UNF) and class fit (e.g., 2B) match your application. OSG taps are engineered for precision in non-ferrous materials.
