Plug chamfer taps are the most general purpose of the three chamfer types and are usually used by themselves or after a taper tap when it is necessary to thread deeper. Gun taps have a longer chamfer and are used for threading blind holes, while twisted taps have a shorter chamfer and are used for threading through holes. Taper chamfer taps are used to start the thread and to guide the tap into the hole, but they are not suitable for threading deeper.
