installing 3/4 sch40 black steel, and my Toledo dies weren’t cutting very clean threads. Teeth were sharp and undamaged, but I went ahead and bought a new Ridgid 12R threader, since Toledo doesn’t make the old die design anymore and I figured the dies were more dull than I thought. I hadn’t used them in 20 years. I’m getting the same, if not worse results. Tear out and flattened threads. Plenty cutting oil and I’m not new to threading pipe, but in the couple decades that have passed, has the quality of steel changed that much? This is imported pipe, but the 21’ lengths have nice clean thread on the ends, so someone’s able to cut nice threads on it.
Thanks
