Drill America seems to make good taps and drill bits . They hold up well

Received today and broke today, Used with hand tool to clean some rusty threads and tap broke half way through with cutting oil being used

Only used once so far, used to clean up a thread for my snowblower.

Appears well made, recommend you don't use an impact drill even on lowest setting... yep snapped mine off in the threads. On me for trying to go too fast.

Good price. Works well.

I ordered this tap to tap new threads into the aluminum oil pan on my 2008 rmz250. The previous threads stripped out. The tap was very sharp and cut right through the aluminum. Just go slow and keep getting the shavings out of the way.

As you can see in the photos the tap exploded on the fourth hole. I should have ordered the taper tap like the picture shows, but I mistakenly ordered a plug tap and it failed. It's a 4 flute design, and it's the first tap I ever broke out of hundreds of tapped holes over the years.

Used in my lathe to make threads in 1018 steel. Worked great

It works. But it's too small for my application

I ordered the small 8-40 tap, I had a scope mount plug screw that was glued in and had the strength of god. I broke an extractor trying to get it out, drilled it and still couldn't get the sucker out.Decided just to retap the hole and threads to see if I could get the bits of old plug out, managed to use this and match the old threads and work it's way out while trimming out the old gunk.I did feel a uncomfortable amount of flex in the bit once I started getting to the tough part and I feel with a little more turning would have snapped it. Fortunately this is all I needed it for but am certain it wouldn't survive tapping new threads in a hard steel receiver.

Well made and sturdy. I used it the first time tapping hardwoods. It cut nicely defined threads. I haven't used it on metal, but expect the same results.

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.
