For blind holes, choose a bottoming chamfer tap like the CHICAGO-LATROBE 306341, which threads close to the hole bottom. Ensure the tap size matches the required thread (e.g., 1/2"-13 UNC) and use proper cutting fluid. Always start with a taper tap for alignment, then finish with the bottoming tap.
