To select the correct spiral flute tap for a blind hole, match the thread size (e.g., 5/8"-11 UNC) and tolerance (e.g., H11) to your application. Choose a semi-bottoming chamfer for threading close to the hole bottom. Ensure the tap material suits your workpiece—CHICAGO-LATROBE taps are suitable for steel and aluminum.
