Drill America 3/8-16 UNC High Speed Steel Tap Set

I used this set to tap threads into a 1 deep hole that bottomed out in a piece of stainless steel. Used all three taps starting with the taper and ending with the bottom tap. All three cut through the hard stainless steel with relative ease and achieved smooth threads all the way to the very end of the hole. So far have done just the one hole and taps look pristine and ready for more. The plastic case they come in is also handy for storage.

The picture show when purchased them 3 different type of tapes. When I received them they all dead front or bottom type tapes. All are 5/8X11.

These tap are marked HSS and seem to be well made. Im threading in Bakelite so they should last awhile.

I needed the bottom tap and used all three. they worked great with ease.

good quality for the price, they work well.

These are not high speed taps, so if you put them in your cordless drill to tap a number of holes, there is a good chance youre going to break at least one. I guess thats why they come in 3s.

I bought the set to chase some threads and finish threads in a blind hole. They worked great and cut new threads easily. I only used the taps for one hole, but they are still sharp and show no signs of damage.
