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

Easy y use

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.

Im an experienced instrument maker, as a shop supervisor and as owner of a business that has produced scientific instruments for many years. Almost all my tapping needs use machine thread taps, but very occasionally need pipe taps. I bought this Drill America NPT tap set to eventually replace my old pipe taps that were getting dull, and put the new set in the tool crib for future use. Several months later, well past to return date, I tried to use the 3/4 NPT tap from that set to tap a hole in a nylon plate. The tap turned very hard for such soft material, and produced a ragged hole with no chips or usable thread. Then I tried to use the 1/4 NPT tap from the Drill America set to tap a brass piece with the same results, and had to finish that job using one of my old taps. Although these Drill America taps look good, the cutting teeth are shallow and will not shave thread and produce chips in any material, even using oversized holes and plenty of cutting fluid. Trying to make thread with this set is like trying to use a threaded pipe as a tap, it doesnt work. Ive contacted Drill American about this problem, and offered to send them a tap for them to look at. Drill American has never responded. Ron Hilliard

great and durable tools , great value for the money.

Great NPT tap set, I taped my water pump inlet 1/2” NPT and the outlet 3/8” NPT for AN fittings, they taped very nicely into the aluminum housing and most importantly no leaks! I would definitely buy them if I needed another set again and recommend to a friend

As described

THEY CLEANED UP THE THREADS IN THE FITTINGS AFTER REPLASTERING MY POOL

This set has all the right sizes, they have not failed and I have used all of them except for one size havent had any issues with them havent had any of them break on me so far I am really happy for the value and set

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!

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.
