ATOPLEE Metric Thread Tap,M12 HSS 6542 Right Hand Thread Tap (M12x1.75)

Quality product for the money.

I needed the tap to install a trailer hitch this weekend and it arrived right on time and worked perfectly to clear threads for the bolts to the frame rails that had been exposed for years.Thanks again Amazon.

I was pleasantly surprised. Very nice tool.

I drive a 2003 Mitsubishi Lancer ES.My manifold cat o2 sensor slot got stripped a bit and it was either buy a new one, or rethread. The better, cheaper and more hopeful option was to rethread.If you're planning on a small project like rethreading your o2 sensor slot(s), this tap bit is the specialty bit size and threading.Size: M18Thread: 1.5Best practices:1. Ensure o2 sensor slot is clean of dust, debris, etc.2. It's possible to do this with a drill, but I prefer by hand. Less chances of drilling out the slot instead of threading it.3. Secure the catalytic converter so that it will not move or get damaged as you attempt to rethread the o2 sensor slot.4. Apply your choice of cutting fluid/oil.5. Place tap into slot and place a moderate amount of your strength/weight pushing it into the slot.6. Begin turning it with your choice of tool, slowly, to make sure you're at the correct angle.7. The bit is designed in such a way that you can see how far in you've gotten. Just remember that a quarter inch of the end of the tap is not thread, so you'll want to go farther into the slot by about 1/4 (quarter) inch to get a full threading completed.8. Slowly remove the tap bit by unscrewing/turning it back out.> It should be good to go now. Test by putting your new o2 sensor into the o2 sensor slot of the catalytic converter.>> If you have an old o2 sensor, ensure it has been properly rethreaded as well. You can do this with what is called a "die" bit. It rethreads bolts/screws/etc. Sizing will be the same as the tap: M18 x 1.5

Works perfect

I like it

Worked well for tapping a new oversized drain hole in my rear differential after I accidentally stripped the threads. This tool cut a clean precise thread.

I first tried a Lisle12230 thread chaser, but that didn’t work to fix my fouled threads.I made the mistake of heating the O2 sensor with a torch and then trying to remove it while still hot. I think the better route is to heat it with a torch and then quickly cool it with either freeze spray or even compressed air a couple times.In any case this M18.5 tap worked perfectly to cleanly repair the partialy stripped bung threads for the O2 sensor.Just make sure you have enough clearance between the O2 sensor in the bottom of your car, because the tap is 4 1/8” long. I had to use open end 1/2” wrench to turn the tap.A nice bonus is that the tap comes in a reusable and labeled plastic sliding case.Another nice bonus is that it was delivered in less than 24 hours.

I used this tap to thread a hole in a master cylinder for my motorcycle. It did the job well and I'm very happy with the product.

Fabulous high quality

Habe schon viel gearbeitet damit, funktioniert gut

J'ai utilise ce taraud pour refaire deux filetages de ma BMW X1 F48 qui avait été foires par Midas... J'ai suivi une vidéo sur Youtube et appliqué ! Avec un porte taraud que j'ai pris sur Amazon aussi, j'ai défait les roues avec un Cric et refait le filetage doucement mais sûrement. Visse, dévisse, et revisse jusqu'à atteindre le Boury. Nettoyage,un peu d'huile et remise de deux boulons neufs achetés sur internet. Résultat parfait! Trop content,c'est top !! Il faut essayer.

Tenias mis dudas al ser de gran diámetro de rosca y usar solo un macho, cuando normalmente se pasan 3, pero con paciencia y poco a poco a quedado la rosca perfecta, recomendable.
