Title : Always clean metric threads. They are not forgiving First I used them to learn about the different metric bolt and thread sizes I was changing the exhaust manifold gaskets on my truck I used them to clean up some of the threads Worked good

Works well for re-threading / cleaning threads. Gold color shed and was ground down to silver, but still functions. Will keep as long as it can be used.

Works well. Cross threaded front tire post on my e-bike. Cheaper to buy the kit than bring to bike shop. Used M12-1.5. Would recommend.

Save yourself a chunk of money and buy this kit. Its the same thing as what the tool trucks sell but without that fancy name.

Messed up a water pump and used this to fix the threads. Worked right away and fixed the issue.

Had to chase a bolt on my e-bike it it worked great for that. As with any chaser/tap set just take your time and oil up the surface and go slow with hand tools only, no drills.
