It fixed the thread!

Nice product. Did what I needed it todo.

this has been a very helpful tool when not having the tap or die on hand, has been a life saver for me on many threads for any sizes

This item isvery useful and worth its money. But material quality and durability is not at high level. I have used several times and it worn out. I expected its lifetime could be longer...

Gooood

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.

Wored better than i expected

Bought these to fix a threaded end on a pipe. They worked great.
