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

Used the bottom tap & it worked just fine

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.

Did the job.

I have bought products from this company before and have been satisfied with their products. With this product the diameter of the shanks was pictured as the minor thread diameter. The set arrived and the diameter of the shanks was the major diameter of the threads. This means that you cannot tap a deeper hole than the cutting length of the tap. This was contrary to Top Dogs question that was answered in 2020: Q: are the 1/4-20 taps like the web page picture, or like the customeer picture. In other words is the shank smaller than the minor diameter? A: As pictured By Top dog on December 7, 2020

good quality for the price, they work well.

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.

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.

I ordered a set of three and just got two. Thats unacceptable

These taps were much easier to use than I had expected, not having tapped anything before. Although its not likely Ill use them often, if ever again, Im completely satisfied.

Performed as expected.
