For aluminum, choose a tap with a polished flute or coating to reduce chip adhesion. This OSG tap uses a V-coated powdered metal design for chip evacuation and wear resistance. Ensure the chamfer type matches your hole: bottoming for blind holes, plug or taper for through holes. Match thread class (H5) to your tolerance needs.
