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

Arrived in good time, and used in Aluminum material tapped gave a great thread.

Im a machinist by trade. I cant say how they would hold up in a commercial setting but in my home shop environment they worked very well.

I needed a bottom and plug tap for 8-32 metal/jewelry working and it took awhile to get all 3 types in one item and purchase price separately was not as good as this offering. They look perfectly all right, so it was felicitous.

Only one tap is a bottom tap. The other two are standard tapered taps.

I spent over 10 years in a machine shop and can say these are legit taps. Not the cheap carbon ones...these are HSS and ground well. True gun tap, bottom tap and plug taps.

These taps were marked HSS and 12-24. There were no other markings for either manufacturer or country of origin on either the taps or the packaging. Are they counterfeit? Who knows? The good news is that they do have the correct pitch and diameter and at least cut in soft metals. These are quite inexpensive taps, so this is probably a reasonable deal for incidental use. They worked fine for the thread cleanup that I have done, but I would probably not use them in production.

Always a great product. Never had any issues. Keep em lubed.

Works as intended.

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.
