I am trying to thread a cold rolled steel rod, 1/2 inch in diameter with about 3/4 inch long thread. Have busted 4 different die holders, and find threading to be very difficult. (No broken dies - yet)
Wanting to know - is there a way to soften up the rod to make threading easier? I have no worries about hardness when done - but I have pretty much run out of local places to try finding a different kind of holders. :mad:
I was using a round die, and it kept spinning in the holder, and breaking off the point of the set screw. I just switched to a hex shaped die and it still seems like I am putting a big strain on the die and holder. After a bunch of hours (including return of the broken die holders) I have managed to thread approximately 5/8 of an inch - with three more threading to go.
!!! I am threading forward about 1/4 turn, then backing up about 1/2 turn, then forward again. Also using cutting oil - not motor oil. !!!
Any advice from you “metal workers” is appreciated.
