Ah-yes, the pleasure of broken bolts! I had exactly the same problem
with replacing the four splash shields on the '85 ur-Q. One of the bolts
on one shield snapped. I think I could have eased the bolt out
without breaking it, *if* I had been more patient......oh well....
So, I drilled a pilot hole and tried to remove the bolt with a bolt
extractor. Of course, the bolt extractor snapped off leaving me
with a real mess. (yes, I *knew* it would also break.....) So now,
I've got a busted bolt with a busted bolt extractor in it. Nice.
Of course the extractor is hardened steel and hell to drill out.
I trashed a drill bit, but eventually was able to drill out the bolt
with the busted extractor in it. The bolt itself was not hardened
and would have been easy to drill out, were it not for the busted
extractor stuck in it. You should be able to drill out that bolt
with no problem, they are relatively mild steel, as the shields
are not at all load bearing. Perhaps you have some cheap
drill bits, or the bolts were replaced some time with hardened
bolts (unlikely) or perhaps the drill is really spinning the
wrong way! Try testing the drill and bit with a block of wood.....
