What is a tap and die set used for?

thread cutting

A tap and die set is a versatile tool used for cutting internal threads (taps) and external threads (dies). The set typically includes various taps and dies that allow users to create threads in a range of sizes and shapes to fit different types of nuts, bolts, and other hardware.

Taps are used to create internal threads in a hole, while dies are used to create external threads on a rod or other cylindrical object. The set may include both straight and tapered taps and dies, as well as sizes ranging from small to large.

Taps often are made of high-speed steel or carbon steel and feature a cutting edge that is either straight or spiral. Many sets also include tap wrenches to help users turn the taps by hand.

Dies typically are made of carbon steel and have cutting teeth that work to remove metal from a rod or other material. They often feature adjustable threads to allow users to choose the proper size for their project.

Overall, a tap and die set is an essential tool for anyone who works with threads regularly or needs to create or repair threaded parts. It is often used in industries such as automotive repair, machinery, and construction.
