Been using 47750 alloy steel dies & getting a lot of chips in the threads with some of the imported pipe. Would it help to change to the high speed steel dies, 47770? A friend threaded some of the same pipe on his threader ( not ridgid) & had no chipping. Don't want to buy new dies & not improve the problem. Could different cutting oil help. I've used Ridgid & brand x with no seeming difference.
