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.
What do you use a tap and die for?

Can I use a tap as a thread chaser?
A cutting tap is designed to create new threads, whereas a chaser tap is designed to clean, re-form and restore existing threads. If you want to clean-up existing female threads (maybe the threaded hole has burrs or a bit of corrosion, etc.), it’s best to use a chaser, or follower tap instead of a common cutting tap.
Can I chase threads with a tap?
Standard taps are actually designed to cut new threads rather than chase existing ones.

What is a bottom tap?
Bottoming Tap: When the lead in chamfer is smaller than 2 threads it is referred to as a bottoming tap. This tap is capable of cutting threads all the way to the bottom of a blind hole. Its lack of chamfer makes them very difficult to start a new thread and keep it aligned with the hole.
