Taps and dies are simply cutting tools that are used to thread metal. The taps are used to tap a hole by twisting the threads to form a hole. Dies, hexagonal in shape, fit into a holder where you then turn them to cut the thread on a rod.
These sets can be used for various things. They are mostly used for metal-working; however, special ones can be used for woodworking.
