NPT Thread Forming Taps - 6 Pieces 1/8", 1/4", 3/8", 1/2", 3/4" 1" Pipe Taps Set with Storage Box Drill Bits for Cleaning or Re-Thread Damaged or Jam Pipe Threads, High-Speed Steel Material

I only used one of the taps but it worked well. I don’t think there should be an issue with the others.

I don't understand why taps can't also have drill points, makes it annoying to fit to the right spade bit hole, but oh well. Gets the job done and you get 5 different sizes! Home Depot doesn't even carry the 3/4 inch size anymore!

Super fast to Alaska, These work great for chasing threads and etc good buy for money.

These appear to be carbon steel, not HSS. They are not very hard, don't work at all on stainless steel, not well on steel. ok for aluminum.

I needed to tape some NPT fittings. Searching online, some had bad and some good reviews. So when I came across these, they seemed to be a good value. Plus, I was unable to find any at my local outlets. These fit my needs just fine and did the job.

These work great!

Comes with 6 taps as pictured. But only 5 are in the case. The other (largest) is in the box. So the case can't hold all of them in your tool chest. I don't love having the cardboard to store them.The largest two sizes are also too large for my largest two wrench. It would have been nice for the set to include a two wrench large enough. I have I think six and none of them can hold the largest size. That said I can use them on my milling machine with a proper collet.. which I also don't have for that size!

Heavy duty and good quality.

This tools is great for what I do.

they look eral good and come in a case i wood buy again thanks

The one inch tap has a pitch of 11tpi, when the NPT standard is 11.5I wrecked an expensive fitting trying to clean the threads before I figured this out.Amazon, I think you should either replace this item or give me a refund.
