BROKEN BIT

[nachoman]

I would rather not throw it away, it would cost almost $100 to replace it. I never thought about using a Dremel tool. How many grinding wheels did it take? I have only used the small grinding wheel once and it went fast. I think I will give that a try.

In my case, I had a bolt that broke off in the cylinder head of my car. I tried drilling the bolt out, but the bit broke off. I think I used 2-3 of the smallest dremel grinding wheels to grind the bit out, and then had to re-tap for a helicoil. It probably took 3-4 hours from the time I broke the bold off until I got it repaired.
