For those that don’t know, pipe is measured by inner diameter, so the die will need to be sized for the outer diameter; also just an FIY tubing is measured by outer diameter.
I guess many Harbor Freight tools are good for an occasional or one time job use. If all goes okay you got your money’s worth.
that (tool) is just really good for is chasing the old threads. a Ridgid electric pipe threader (Industrial machine) is the best for new threads. I would measure and mark all cuts and take it to a machine shop and in no time hardly they will be threaded to ensure I have a good seal.
Hay Pete.Your a guy that works hard to work hard.geter done.
Dang it Pete… looks like that Harbor Freight is as much a negative thing as your saying… and the peice of failure Monte Carlos, I drive…
O'well… Whadda ya' gonna do…..
There are a lot of approved piping for air at 300 psi brassed copper black iron and galvanized pipe brass pipe and stainless
I have hand treaded 2” pipe it’s a pain but it helps if you got a heavy friend and a 4 foot cheater
Lots of people are stating you need more oil and I agree but, the technique also needs modification. Most than likely the dies are a high carbon steel (cheap) and NOT H.S.S. (High Speed Steel-expensive). I noticed you only backed off after the threading became very hard. When the threading becomes difficult, there is NO oil where the dies are cutting through the new metal. You have to reverse and re-oil long before it gets that tough to pull the handle. Your threads prove that out.
Def need more oiling. The hotter the thread gets the better chance it will temper and shatter the thread. Aerosol Ridged cutting oil is perfect for hand threading. It bonds to the pipe very well. 🤟🏼
I bought that set at least 10 years ago and I've had very good luck with it. I used the 1-1/2" a lot. I use a plumber's style pipe vice on my bench and I also bought a tow extention mount chain pipe vice to use on the back of my truck. My 1/2" cutter is finally getting dull, but not enough to motivate me to figure out if the bits can be replaced, or if the entire cutter interchanges with a Rigid, etc.
