Thread Repair Tool, File, Chase, Restore, Repair, and Clean Internal and External Thread: Male, Female, Inch, Metric and Pipe Thread (RT1) (3/8 Dia. Head x 2 Length x 1/8 Arbor) by Rotary Thread

Works great! Was really easy to use in my dremel.

Im a mechanic. Damaged threads are just part of the job sometimes. The case that brought me in contact with this tool was a spindle on the rear end of a Dana 80 truck axle. It would have required a $200 3 threading die. I decided to try this tool. I took something that looked beyond repair and transformed it to the point where the large lock nut spun on by hand. It takes some skill. Its not a toilet plunger. You need to have a steady hand and a good Dremel tool but the payoff is quite impressive. Its a tool anyone who works on anything threaded should have. It saved my butt and a buttload of money as well.

Although I was shocked by how small it is - it saved a damaged 3/4 threaded rod I had already welded to a bracket. I used a Dremel and magnification and was able within a few minutes to get the nut to travel the full length of the rod. ONE LIMITATION is this works best where you can get the tool perpendicular to the threads being repaired. Even using a Dremel extension I had to work at a slight angle 6 from the end of the rod which wasnt a problem due to the large threads I was fixing but it could be an issue on finer threads.

Works exactly how the description said it would.

I bought it to use in my shop in place of a thread file. Its smaller than I expected but thats a good thing. Has been useful and effective.

I purchased this tool after watching a review of a similar product on YouTube. This one is very similar if not the exact product. Works great with a high rpm impact drill. Also it does take a little getting use to at first, my suggestion is lock down whatever your working on and use two hands to control the direction of the drill as well as the recoil of the spinning bit. Also go with the direction of the drill while using. LIFE SAVER!!!

Great tool to fix and reform threards that may be damaged, rusty or very gunked up.

It fix any bad thread. Highly recommended. Easy to use.

The result isnt as pretty as using a tap or die to repair threads but it works surprisingly well and is much less expensive than buying costly tools you will probably never use again.

I bought this to clean up the threads on a part where the threads were distorted by welding. This tool cleaned them up nicely in a matter of minutes. I also used it to clean up the rusty threads on our main drain clean-out fitting which was pretty messed up after nearly fifty years. Fifteen minutes later the threads on the drain and cap were cleaned up and the cap securely screwed on. I would suggest when working on heavily damaged threads that you stop occasionally to flush the rust or metal particles out of the threads. And no matter what, flush them out when you are done.
