Head bolt - gone

[David Templeton]

Hi all,

I picked up a cobalt drill bit that was the same size as the bolt shank.
Used a puny 7.2 volt cordless drill and the head of the bolt came off in
less than 5 minutes of work.

Tried then to pry the head off and it will not come off. Is there something
I am missing?

Thanks for all of the advice so far
