Qualtech 1/2"-20 HSS Machine and Fraction Hand Tap Set, Qualtech, DWT54741

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.

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 can't get much torque with one. I'm 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 I'll spend the extra money and get something a little higher quality.

Worked Great , Good Products ,Great quick delivery as needed as soon as possible to straighten out a Club Car President with Frt. End Lift issue.

Apparently there QC is not very astute. The tap packaging was labeled as 1/2"-20, however the actual taps in the package. Well they were 1/2"-13. Verify the actual item matches the package label, that is the lesson to learn from this.
