6-Piece NPT Pipe Tap Set, Precision Carbon Steel NPT Tap Set for Clean Accurate Threads, 1", 3/4", 1/2", 3/8", 1/4", 1/8" NPT Tap, Perfect for Plumbers Mechanics DIYers, with Durable Plastic Case

They are exact to specs and work well on cutting new threads in steel or in cleaning up damaged/rusted threads in old pipe. Good tsps at a reasonable price!

Nicely made set of NPT Pipe Tap I understand they are not a set of Hanson taps but I rarely need them and these will do just fine. Very inexpensive to purchase

Worked great for me. I had a bad aluminum valve that was cold welded into another aluminum fitting. The bad valve broke off at the fitting so I was able to drill out the majority of what was remaining and then re-thread using these. Worked perfectly.

I needed a 3/8 NPT tap for a project I am doing. So I ordered this set. I already have 1/4 and 1/2 NPT taps. The ones I have are imprinted with their size and the proper drill size to use. These inexpensive taps only have their size on them. Not a big deal as I asked SIRI what drill size for the 3/8 NPT tap and got the answer. I also had to grind the taper on the tap so it would start in the hole. Not great quality.

Great set.

Excellent Product.

We all hope there’s a cheaper way to do something- I did with this tap. Trying to chase threads in a cast iron 1 1/2” plumbing drain line- just needed a tap to clean up the threads for a plumbing project. Unfortunately it was apparant a few turns in that the metal was flattening instead of chasing threads, which ruined the threads and forced replacement of the cast iron pipe... Turned a small project into a large one- buyer beware.

Electrician, didn't know how much i would use it
