A funny fact about tap and die sets is that most people tend to think of them as tools used for plumbing or car repair, when in fact they were first used for watchmaking. Tap and die sets were first used by watchmakers in the early 1800s to create screw threads in small watch components. This allowed for more precise and intricate designs to be created, something that was previously impossible. According to the Smithsonian Institution, tap and die sets allowed watchmakers to make smaller gears and other components than ever before, paving the way for advancements in watchmaking and other precision engineering fields.
