Drill America - POUCSNPT5 5 Piece NPT Pipe Tap Set (1/8, 1/4, 3/8, 1/2 and 3/4), Plastic Pouch Case, POU Series

I used the 1 npt tap to clean some very rusty threads in a cast iron well pump. The tap did great and cut well. Tap was undamaged after using.

This product works great. It was cheaper than I found anywhere else. It sure works just as good if not better than the rest. Product came sooner than expected so I was able to get the tractor fixed before expected. It helped me out tremendously.

My husband says they work great!

Was a good deal but I am missing one. So definitely not 5 stars on this. Went ahead and bought some from Granger. No reason an order like this they couldnt check before delivery process.

Great value. Will cut threads in anything a mortal person can drill a hole big enough for these taps... Soft metals and plastic. I would not use these on steel or cast iron except to clean up a damaged thread. I cut some nice threads in 1/2” polycarbonate for a fish tank filter. Great capability to have in the tool box. Great in a pinch or for fabricating things for fish, aquaculture, irrigation, or around a farm.

used this to chase the threads in a water heater. the next day there were spots of rust where I let the water sit too long I suppose. probably should oil these after every wet use.

The price of the pipe tap set is great. I have spent the same amount on a single tap at my local hardware store. The quality of the tools is very good. I have used two of them already with excellent results.

I messed up the treads on my pvc pipe coming from my sprinkler zone. This tap saved me a lot of work digging a big hole to fix pvc pipe. I’m a noob and ordered the set because I didn’t know I only needed the 1/2 tap. So all in all I’m happy. Worked great tapping a pvc pipe, It only took 16 hours to get this at my doorstep from Amazon!

These are very soft, maybe good for some plastics or low grade aluminum but definitely not meant for steel of any kind. One use, didnt cut threads, rather, the material took the teeth off of the tap. Definitely not what you want for a tap. Maybe I selected the non heat treated option? Kidding. Steer clear of this set, not worth buying.

great and durable tools , great value for the money.
