How to select the right extension tap for deep hole threading?

Select an extension tap like the CHICAGO-LATROBE M12x1.75 based on thread size, chamfer type, and material. For blind holes, use a plug or bottoming chamfer; for through holes, a taper chamfer works. High-speed steel suits general machining; ensure the extension length reaches your hole depth.
