We use these at work quite frequently, they are great even if a bit slow. most useful when you have a very odd size and are not able to get a proper die. also they work better that a die when the end threads are damaged and a die would have trouble starting.

I believe that the ones we use are made by Jaw manufacturing (http://www.jawco.com/page2.html) and are usually on sale in the monthly flyer from ENCO (http://www.use-enco.com) for about $7.00 a piece

its money well spent the first time you have to use them to salvage an expensive part

Looks interesting and as Greg said they would be helpful after cutting. As it is now, before cutting I thread several nuts on the bolt/rod and run them off the end after cutting. This seems to do the trick for me.

These things are great, I have used them for the ends of all thread after cutting it to restore the threads works quickly and like a charm

I have a thread file made by Cal-Van that has 8 different thread pitches and I use it all the time. They’re great when you have damaged threads in the middle of a long bolt or threaded rod. Very effective and handy to have in your toolbox.

These work well, and you basically just slowly file around to get the threas back to shape, using the existing threads to guide. You can achieve the same thing with a triangular file but it’s harder to keep the spacing right on severely damaged threads.

These also work great as a poor man’s checkering file…
