Drill America DWT54455 1/4-20 UNC High Speed Steel Bottoming Tap, (Pack of 1)

The pedal on my daughters bike got boogered up, and when trying to take it off, the threads were damaged. I didnt have any other way of fixing, so I was going to replace her bike. This little purchase saved me 100 bucks. Worked great.

Ive 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 thats 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. Its 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). Id 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 youre 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, theyre ok.

Worked great
