broken bolt and drilling when everything else has failed

[Jack_and_MLE]

Hello All

I have a high tensile bolt which sheared of
I have tried drilling it out with cobalt drill bits and have failed.
The bolt has broken into the chassis of the car

Can someone one recommend a company who specializes in removing broken bolts around Oxford Didcot?

Cheers

yes correct and body work in the way so could not use heat

Which drill bit did you use? very expensive cobalt?

The Nitrogen looks cool!

However, I have given it my best shot, spend hours on it and the broken bolt is still it

I've found a local company who should be able to sort it for the same cost as a new drill and drills bits.
