Official info (translated):
"Thread Rolling Dies ensure formation of the 6th degree of accuracy in accordance with GOST.
Roller material - chrome or alloy tool steel. Multiple-thread rollers.
Dies are self-threaded on the wrap that allows multiple reinstalls.
The total resistance of the dice is 25-30 times higher than cutting dies.
Manufacturer - Kharkov Tool Factory"
My personal thoughts:
Rolls excellent thread even on worn rods
Raises a thread to the proper level even on the average fasteners.
If you use a lubricant (highly recommended), it is practically unbreakable, you can forget about regular dies.
Also can be used for thread rolling on spokes, where conventional dies are unacceptable.
