To select the correct CHICAGO-LATROBE tap, match the thread size and pitch (e.g., 3/8"-24 UNF) to your application. Use a spiral point tap for through-holes and a spiral flute tap for blind holes. Verify the chamfer type (plug, bottoming, or taper) based on hole depth. Always consult the manufacturer's recommendations for material-specific speeds and feeds.
