Awesome tool everyone who works on any machinery,cars,trucks, farm eQuipment etc should own a set of these.
I run across damaged bolts quiet often and this tool has made it do I dont have to find new bolts just cause the threads are damaged. Its easy to use and its great that it comes with a adaptor piece the smaller bit.
Saves me 5k. I cleaned up thread on spindle of semitruck axle thread. It was like 30% missing this thing cut right through. Was able to change bearings and seal nuts went on amazingly.
Was invaluable on this heavily damaged shaft. Helped me define and clean the threads along with a thread file. Final repair shown.

This product saved me from having to buy a $200 part for my car’s emission system. Follow the directions, work slowly and you will get clean usable threads.

This thing is a must have. Saved me from having to buy a 300$ tap for an M27 thread on a pair of stainless long tube headers. Cleaned up the threads well and allowed me to install the correct fitting.
