Repair Tool, File, Chase, Restore, Repair, and Clean Internal and External : Male, Female, Inch, Metric and Pipe (3-Piece Starter Kit)

Poor quality. I excepted more out of the great americas. Definitely not worse the money since its not a qualitativ product.

This is a must have set. Ive been so impressed ive ordered a second set. As a farmer i come across rusty,damaged and corroded threads all the time. This tool has saved my thousands already. YES thousands!! Working on a John Deere 2510 anhydrous rig i have busted threads on almost every shank from anhydrous damage.To replace these blocks it wouldve cost me $200 dollars. The small one in the kit along side my cordless dremel worked flawless. The threads where 5/8th and id say you could go up to an inch with the smaller one maybe more with fine threads. Ive used tge big one once on a damage hydraulic cylinder end that woikdnt except a nut. Thats where it shines. More times then none its the first few threads that are damaged. With this tool you can start behind the bad threads and work towards them in a reverse motion. It takes a little time to figure out how fast you need to go with your movement and with the speed of your drill or dremel.Ive learned start slow with both on the first pass then speed up gradually until fixed.If youve read all tbis you can tell im impressed and this is coming from someone who owns alot of tools. Only regret is i hadnt found it sooner.

Expensive but it does work well

Works great and as described good quality

Edit: the company got ahold of me and did right by m. Although they never did me wrong. Original review was 3 stars. Adding 1 for the great customer he service. 2 wheels are pretty much the same thickness just a different diameter so that doesnt help with varying thread pitches. They do work pretty well, but not for the application/s that I specifically ordered them for. Also, heed the label saying to use light pressure. You WILL mess up your threads even worse than they were if you use to much pressure. It would be a good idea to practice on a spare nut or bolt to get an idea for how rapidly these will rip off rust at varying angles.
