Drill America-DWTH112-14NPS 1/4"-18 NPS 1-1/2" OD High Speed Steel Round Adjustable Pipe Die, DWT Series

Works great! I don't have a handle for it so I locked it in a vise while rethreading a tappered pipe, and it worked well.

1/8-27 NPS is what it says. This is straight pipe thread. Good mostly for lamps and lighting. It worked fine on hard steel tubing. It is high speed steel. It was sharp and cut a clean thread. 1" OD fit my die holder just fine. Fit and finish are good. Yes, it is made in China but the quality is good on what I received.

did the job

Did not work well for me on PVC pipe as a re-threader - looks to be of good quality.

This 1/8-27 NPS die is marked Made in China. I could not find country of origin disclosed on the Amazon listing and had hoped that it would be made in USA since the company is Drill America. Quality may be just fine (or maybe not) but I do not want to support China. I will be returning.

Maybe okay for repairing damaged threads, but worthless for cutting new threads. Well, it makes threads, but way less than 50% engagement in proper 1/8-27 NPS female threads.I'll get my thread micrometer out someday when I'm bored and check it out.
