ok the buts i have wern't eve making a scratch

Get some Bits then! sorry!

I forget the name of the bits we used on hardened steel , but there are a lot of quality bits available . As has been said , if possible centre punch to give the bit a start , use cutting oil and start with a small bit as I suggested earlier. It went in - it will come out with patience .
I take it this is a quality job and you cannot have an uneven line as @snowhead suggests.

How on earth did you snap it in the first place, those bolts are pretty tough normally!

I have seen a electric gate fitter weld a piece of metal on the end of a broken bolt before as the head had snapped off, as the piece of metal was quite long he could use a bit of leverage to turn it anti clockwise and free it up and unscrew it.

That's fine if there is enough to get a weld on to it. Another method is to hammer an oversize nut onto the stud and weld that to it.

Patience will get it out.

Do you know her number, we could give her a call, she could bring her e-z-out kit!

masonry drill all round it in the concrete. get it out. refill with fine concrete mix. go back next day and re-drill for new bolt.

I would have it out in 30 - 45 minutes, the bolt that is.

Cobalt drill bits are the only bits that will do anything.
If they don’t work, you’ll have to drill down the side of the bolt.

Cut the head off a bolt super glue it over the hole collect money disappear...........

 

[davesparks]

Left handed drill bits are my preferred method of drilling stuck bolts.

Core drill around the outside of the bolt if you can't get it out by using HSS drills and a bolt extractor, then use one of those resin bolt kits to fix a stud in to the hole. Ignore baddegg as he doesn't have a sense of humour.........

Ha ha apologies swd I didn’t mean to give you a disagree,

For anyone not yet sold on cobalt bits, I drilled a hole, through a drill bit! To prove it's not just some picture I found on the interweb, there's my username in the pics...
