A die cuts an external thread on cylindrical material, such as a rod, which creates a male threaded piece that functions like a bolt.With hard materials, the machinist may start with a taper tap, whose less severe diameter transition reduces the torque required to cut threads. With soft or average hardness materials, such as plastic, aluminum or mild steel, common practice is to use an intermediate (plug) tap to cut the threads. This problem is particularly acute in blind holes, so thread forming is particularly suited to such applications. Even threads with multiple strands such as embroidery thread can be easily threaded through the needle eyes. Threading taps are used in conjunction with a tap wrench so always consider the maximum side tap your wrench can hold when purchasing.

You're doing this by hand, and it gets hard to cut the metal pretty quickly -- after about a quarter turn the tap gets very stiff. Although in general machine tapping is more accurate, tapping operations have traditionally been very tricky to execute due to frequent tap breakage and inconsistent quality of tapping. Thus builders of, for example, locomotives, firearms, or textile machinery were likely to make their own taps and dies.Note that the tap drill size is larger than that used for a cutting tap as shown in most tap drill tables, and an accurate hole size is required; a slightly undersized hole can break the tap.

In other words, tapping uses the tap part of the set and creates internal threads and threading is the process used by the die to cut external threads. Additionally, threads come in several different gauges, although usually there are only one or two standard options for any given screw diameter.
