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

Nicely made taps, but not a set of 1 each of taper, plug, and bottoming taps as described. Replacement set the same so did not bother to return replacement set.

I had purchased these taps to clean out Frame Rail Weld Nuts in a 16 year old car. A lot of rust and road grime. The purpose was the installation of a new trailer hitch. When they first arrived I was impressed with the nice divided case that they came in. Very convenient especially considering the low cost of the set. That is where the good for this project ends. The first two snapped within minutes of use in the first nut. This was very surprising as I was using a T-Handle Tap Wrench and you cant get much torque with one. Im guessing these either had a bad temper or were from a bad batch of steel because the third lasted for the rest of the project (6 additional Weld Nuts). Next time Ill spend the extra money and get something a little higher quality.

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

I used grade 8 bolts into schedule 40 pipe after drilling and tapping. The tap started and cleaned easy.

Works great. Used it at work to tap out some screw holes.

I am frustrated at the photo not accurately representing the product. The product photo shows the threads wider than the body so you can tap both sides of a tube with a single tap. What was delivered did not look like the photo. I wouldn’t have ordered them.

havent used them much but they work as expected and have not broken yet.

There 1/4 20 but there a cheap tap so be carful not to make a bad job even worse with them.

The taps look OK. I have not yet used them. However, a set of 3 was advertised and I only got 2 in the package. It was not worth the effort to try to return them, but I feel cheated.

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