Impossible bolt- need tricks and suggestions

The teeny ones you pictured will vanish instantly, but the fiberglass ones last a lot longer.

(Edit: As I said, I wouldn't recommend going out and buying one just for this purpose, but if you've got one available it will certainly do it)

Even better than the above is the EZ-Lock kit:

These are basically miniature angle-grinder blades, and come with a handy quick-change collet. This is the shaft that I have in my dremel 90% of the time. The EZ-change discs are slightly larger and thicker than the screw-type version, and seem to made of sterner stuff. I very rarely break them.
This is the first tool I think of when tasked with "I need to cut through a bolt in a tight space." I've used them on tool steel, hardened steel shafts, steel plate, etc. Sometimes you use up more than one disc on a job, but the small size allows you to get them into places which are otherwise inaccessible.

I have a Ryobi version of the Dremel and it is good quality. Sometimes the access requires a smaller tool like the Ryobi. I prefer the air cut-off wheel for slightly larger jobs and the angle grinder with a cut-off wheel for the ones with good access. You can never have enough cutting tool variety in your arsenal.

I've used a Dremel with regular cut-off wheels to cut a nut off a sway bar that the owner manager to round off beautifully.
That took ages and several cutting wheels due to them wearing quickly and snapping if I used the wrong angle.
When I finished I looked like a WWI fighter ace, there was black crap all over my face except where the safety goggles had been.
Tip: If you start rounding off a nut/bolt, switch to another tool, the one you're using is just making things worse!
Unfortunately those nut-busters/crackers tend not to fit in the spaces where you need them and often you can't even fit it over the nut because they're so thick :(
I've got 2 in my collection though because they're worth trying first.
