Thread repair file

[LMMasterMariner]

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.

Cheers,
