Both taps and dies are used to create screw threads. Some sets are used as cutting tools, and others to form the threads. Taps cut or form the female of a mating pair or nut, while the die cuts or forms the male, or bolt. Tapping is the tap-process of cutting or forming threads, and the die-process is called threading.

What kind of tap is used for blind holes?
Spiral point taps are ideal for machine tapping of through holes, or blind holes where there is enough clearance beyond the threaded portion to accommodate the swarf. SPIRAL FLUTE These taps are used to produce a thread close to the bottom of a blind hole and therefore have a very short lead.
