Thread repair file

[Eloy Workshop]

Thanks for the comment, you're absolutely right! according to the manufacturer that end is to review the internal thread of a nut.... which is very very complicated and above only for large nuts where it allows you to enter with the piece, sincerely the only use I see it is to verify the thread pitch that has the screw to know which face you have to use from the file, greetings (translation)

I see thread files on Ebay all the time for under 24 bucks some as cheap as 12 dollars but they don't have the extra grinding on the ends for internal threads but those extra grindings are pretty much useless anyway as far as i am concerned

Thank you very much for the commentary, because I have discovered it right now... ajjajaja the truth is that I had never seen it and I thought it might be interesting to show it on my YouTube channel, very interesting about the triangular file, greetings (translation)

These thread files have been around for longer than I have, still useful in some cases when a threaded part is protruding from a machine you do not need to dismantle but it has to be the right pitch. I find a triangular needle file and eye glass has got me out of trouble many times.

Thank you very much for your information and above all for the images, I discovered this tool very recently and I thought it might be interesting to show it on my YouTube channel, I have to say that in the second photo I have no idea what these three tools are with the orange cover, greetings from Spain (translation)

Very useful tool.
Inside my threading drawer I have good HASE thread restore file and also cheap Chinese one.
But one of the best internal restore tool is NES thread repair kit. Have NES1007 3-Pc Internal Thread Repair 3-Piece Set 5/16" - 13/16, M8-20, which I also keep inside that drawer and this is the reason why I don't have plastic case anymore. I got it as a present, otherwise I wouldn't buy that expensive stuff. Used it several times and must say that this one is much better than thread file.

This is the tread file i prefer If there is a nick in a thread i fund the single edge file to work better. You may want to ask the seller if he shipp's international

I used to have the external thread repair tool shown but never had the internal. Those truly are fine and handy tools

Isn't the internal thread repair tool called a tap ?

If all you use the thread files for is cleaning up threads, but I also use one for doing checkering on steel parts, like safeties and bolt handles on firearms. Works real well, once you get the hang of it. It's not bad on hard woods, either!
