For roll tapping, cutting tap drill sizes should not be used. Roll tapping displaces metal from the hole walls to form the threads so cutting tap drill leaves to much material in the hole.

Roll tapping is a process which forms a thread in the hole by displacement of the material into the desired size and pitch. Roll tapping eliminates the problem of chip disposal. The threads produced with roll tapping are stronger than cut threads because the grains are continuous and unbroken, and the displaced metal is work hardened. Roll tapping is a method to be applied to relatively ductile metals such as low-carbon steel, leaded steels, austenitic stainless steels, wrought aluminum, magnesium, copper, and ductile copper alloys.

Reaming — Reaming has been defined as a machining process that uses a multi-edged fluted cutting tool to smooth, enlarge or accurately size an existing hole.

Tap: A mechanical tool used to make a standard thread through a hole. Different type of taps exist such as straight fluted taps, spiral pointed taps, spiral pointed only taps, spiral fluted taps, fast spiral fluted taps, thread forming taps, pulley taps, nut taps, and pipe taps.

UNEF (Unified National Extra Fine): Used when finer pitches than UNF are needed (Ex: Short engagement length).

UNF (Unified National Fine): External threads of this Fine Series have greater tensile stress area than comparable sizes of the Coarse series. The Fine series is suitable when the resistance to stripping of both external and mating internal threads equals or exceeds the tensile load carrying capacity of the externally threaded member. It is also used where the length of engagement is short, where a smaller lead angle is desired, where the wall thickness demands a fine pitch, or where finer adjustment is needed.
