Default Re: Broken stud

Thank You all for some very interesting answer. No I did not used an heli coil I drilled the hole out with different size bits until I finished with a 3/8 bit. Then I could run a 7/16-14NC tap to clean the threads. But apparently I did not drill deep enough to thread the full 21/32 which is how deep the hole should be at least. As stated in George Miller's post. I did use a bottom tap. I went back out to my shop and was thinking of try my Drimrel tool with a small grinding bit.Working very carefully I managed to get about two more threads deeper.Now I think I had better leave will enough alone. Once again Thanks Richard
