Price was nice and it did as good as more expensive taps.

Exactly as described, I was able to tap town to near the bottom of my pilot hole in cast aluminum.

Used it on mild steel, worked fine

I had some threads gall up on my motorcycle exhaust. I used this to clean out the threads and it did a good job.

Based on most reviews I was hesitant to purchase this but I figured for the price even if it didn't work, I wasn't out too much money. Now, I'm not sure what others are using it for that they're breaking these but I used it on an aluminum transmission housing to rethread a hole that stripped out and it worked flawlessly. I'm no master tapper (is that even a thing?) but I definitely recommend this to anyone needing something this specific. I used the M12x1.25 which is a VERY specific size/thread pitch for Japanese cars (not sure on other imports, though).

Great lefty tap that was just what I wanted.I couldn't find ANY left hand taps at ANY local hardware store.I guess it's an un-tappedmarket here.Sorry, I had to.

I bought this with a cheap hand tool for the tap and that's how I planned to use it. I needed to re-thread the bolt hols underneath my van that had become encrusted with rust and crust. I got 5 of the 6 working fine, but one seems to have not had enough material remaining. Not this products fault though... at least I don't think so.Anyway, It did what I needed. No more no less.

works great just as stated

I've gotten a few of these from Drill America as well as some other brands...some are clearly the same manufacturer and some are different. The ones from Drill America are quite inconsistent in varying aspects. The steel is a decent hss, not the cruddy low quality M50 type, so that's good. For this tiny M2 bottoming tap the teeth are ground well and the tip looks good. About 11mm of depth with a taper up to the shank. The square flats are a little rough but once again they flubbed the heel. It's chamfered but not to a point, nor is there an indent on the flat. This makes it hard to use a follower and with very small taps like this, you really should use a follower/guide to ensure that you are plumb with the hole. Failure to do so almost guarantees tap breakage (true for large taps as well but you have a lot more room for error there, generally). I'd say if you need standard quality, pay the difference and get a good tap. These are not terrible, though, and they are a LOT better than the junk that comes from many vendors or in those watchmaker tap kits (stay away from those unless you're spending big bucks on a set). I got the 3pc M2.5 set on this order as well, and that was a small disappointment but again, they're ok.

TOOLS I NEED TO USE THEM TO SEE HOW THE PERFORM IN CUTTING AND STAYING SHARPDOSNT TUST ARE LOOSE COLOR, I WILL GET BACK AND LET YOU KNOW.
