I bought this for 1 very specific reason. I needed a way to clean the melted 3d printer filament from my nozzle threads as I swapped them out. This is absolutely perfect for the job! Most 3d printer hotend nozzles are m6 threads and it having wrench flats makes it easy to put in a vise. For the $ this is the best option for what I needed it to do.

Ordered M24x1.5 hex die to freshen/salvage the thread on a CV joint hub. It works as intended. $34 for one, Chinese-made tool, which will probably sit in my workshop drawer for another 10 years, unused. Take it or leave it, I was unable to find anything locally, and replacing the hub would easily cost close to $100.It does seem pretty robust, though. What I like is that it's thick enough to turn it with a large wrench onto. I didn't have any box wrenches or adjustables big enough to accomodate it, so I wound up using a monkey wrench. Not my best moment, but the job got done, and my BMW is back together.The hex dies that have the recessed area and matching bad reviews seem to be for smaller diameter threads.

Solid product that solved my issue!

Rethread some bolts

I used it to clean up some damaged threads on my 2012 Ram 2500's rear wheel studs. It cleaned all 16 easily with plenty of more life left.

Excellent little die. It is very small and a bit hard to handle but such is the nature of a tiny tool. Very affordable.

easy product to use

Works for me. However I was only chasing out damaged threads as opposed to cutting new threads.

Worked great

Cut too much percentage of thread off bolts
