Review on 💧 Ridgid Dark Thread Cutting Oil - High Performance 1 Gallon Dark Pipe Threading Oil, Black by Edwin Kreps

I tried another brand of oil which I could tell was hot and bubbling from the heat. I switched to Rigid Oil and it was like using a different machine with brand new dies. I've threaded up to 2" with a 400 hard lathe and the oil keeps the threads and dies cool and it drains well through the pump gun. The best advice anyone has ever given me about threading is that oil does the threading.
