Stainless steel rmc

[haakefan]

So I've done a good amount of galvanized rigid, a little bit of rob-roy, and now im working with a lot of stainless steel conduit. Were running into an issue where we keep getting these kinks in the couplings that throw off our straight pipe runs. We figured that if we overthread our pipes a bit we can get it looking a bit straighter, but its not perfect.

Does anyone have any good advice on how to work with stainless? Ill take any tips or tricks, this stuff can be tough to work with.

Find cutting lubricant that works better with stainless?

Replace threading dies?

Are you using a power head but a hand threader and letting the handle rest against a fixed object that is putting some lateral pressure on the pipe as you thread it, but leaves a slight bend with direction of deflection based on where you stopped? If cutting die is attached to the threading machine you wouldn't have as much chance of lateral pressure and should have fairly even pressure from all directions on the threading assembly.
