To select a spiral flute tap for blind holes, match the thread size and pitch (e.g., 1/2\"-20 UNF) to your application. Choose a tap with a semi-bottoming chamfer to thread close to the hole bottom. Ensure the flute design evacuates chips upward. For oversized threads, use an H11 / 1B tolerance tap like the CHICAGO-LATROBE 313534. Consult a tooling specialist for material-specific recommendations.
