no a tap and die set are used to either add threads to a hole or thread a bolt. Im talking about thesex2, a Tap and Die set correct? Or am I thinking of something else? //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

basically you use a drill to drill a hole in a screw or bolt they have recommended drill bit sizes depending on which extractor your going to use. The extractor is tapered you can put a socket on them and thread it into the striped bolt the extractor has reversed threads so when you back the extractor out it actually bits into the screw tighter and backs the screw out for you.
