Re-Threaders are Ideal for: Quickly cleans and re-threads fixing holes in socket-switch or conduit-boxes which can often be blocked by cement or plaster and have malformed threads. Solid dies cut a nominal thread form and depth, whose accuracy is subject to the precision the die was made with, and the effects of wear. If you are using a taper tap, you may need to drill a deeper hole to account for the part of the tap at the end that doesn't create complete threads.

This instructable will focus on primarily the use of taper taps, although there will be some mentioning of bottoming taps. Tap and dies can also be used to clean existing threads, freeing the grooves from build-up or dirt and debris.Additionally, threads come in several different gauges, although usually there are only one or two standard options for any given screw diameter. You're doing this by hand, and it gets hard to cut the metal pretty quickly -- after about a quarter turn the tap gets very stiff.
