How do get bolt out?

[blinky phil]

have managed to remove bolt with end stickg out, but still have problem of trying to remove th one bolt that is flush with easy out broken off inside it, wondering what best type of drill bit should be used i have tried many drill bits all different type the only hole i managd to create was with my dremel using diamond tip but i managd to run out of those, was wondering whether you can buy diamond drill bits and where, or if there is another way

Feel sorry for you dude, been there many times myself!
I've heard of a spray that freezes the bolt to shrink it - the opposite of heating the surrounding metal - but i haven't used it, so i spose its only a rumour! good luck
