To select a spiral flute tap for blind holes, match the thread size (e.g., 1/4\"-20 UNC) and chamfer type—bottoming for threads to the hole bottom. Choose flute count (3 flutes for general use) and tolerance class (H3 for standard fit). CHICAGO-LATROBE taps are a reliable choice for consistent thread quality.
