Re: Quick save on bolt with end threads damaged
The Uniburr finally came in this past week.
This version is for hardened steel. To test it, I damaged the threads on the end of a bolt and verified the nut wouldn't engage the threads.
The tool instructions advise a maximum of 600 rpm's. Ay first I wasn't able to make any shavings and I found by varying the engagement angle, pressure and speed it started to work.
Once I figured that out I was making shavings like in the picture above, the end chamfered nicely and the nut would turn onto the threads.
And you guys are probably right...now I have this I will never need it again. That would be OK!
Apologies I couldn't get a clear picture.
