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

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

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

Great for the money.

Used for manual thread cleaning. working well even w/o lubricant

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 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.

Good HSS taps for us

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.

Was just tapping aluminum, but did a great job. Had some mounting bolt threads that stripped on a Kohler engine. I drilled them deeper, and tapped with this set. The bottoming tap gave me a few more threads to screw in to.

cant have to many 1/4x20 taps
