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

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 file worked amazingly well on a decades old floor drain that was rusted.. I recommend it to anyone with any thread problems..

I run across damaged bolts quite often and this tool has made it so I don’t have to find new bolts, just cause the threads are damaged. It’s easy to use and it’s great that it comes with an adaptor piece for the smaller bit
