Tapping is when you threads are cut into a hole. A die set is used to cut threads onto a cylinder (bolt). To use a tap or a die, first determine the number of threads per inch (TPI) of the part to be fixed. A gauge system that has a number of different pins can be used to calculate the TPI of a bolt or nut.
A coarser Square thread or Acme thread tap and die would be good for wood as they should be stronger and more durable than the common V threads, especially for soft materials.
There are times when a Plug tap can be used to start a thread without using a taper tap first if the Plug tap is started with a guiding center or fixture. In blind hole applications, Plug taps are used after a Taper to get closer to the bottom of the hole.
Threading and tapping are the operations used to produce screw threads. Threading is an operation in which threads are produced on the outside of a component or we can call them as external threads using a die whereas, tapping is an operation in which internal threads are produced using a tool called tap.

Taps contain a chamfer at the beginning of their thread length. The primary purpose of the chamfer is to allow the first few cutting teeth to make progressively deeper cuts. This reduces the force the user requires in order to spin the tap as well as reducing wear on the tool.
A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called tapping, whereas the process using a die is called threading.
