yeah, that's a good idea, take it back to the monkey that was too stupid to tighten the bolt up properly in the first place and entrust him with the rather more precise job of drilling it out without doing any damage to the rim.
On second thoughts......................

Reminds me of the only time I've let Costco fit my tyres. On the W126 they did look up torque settings and mistakenly chose those for the W140, which are 40 Nm higher. Fortunately I saw the error on the job ticket and persuaded them to check again -- they took some persuading, but finally admitted the error.
As in my thread, I have got rid of those bolts on all of my own cars.. its simply not worth the risk.
Although I got some from franey recently which seem a LOT better made.

I have one at the workshop recently.
The locking wheel bolt key snapped off then the head of the locking wheel bolt snapped off.
Drilling was impossible. I had diamond drill bits that would not touch it.
I welded a nut to it. It snapped the weld etc etc
I tried everything for hours.
I ended up cutting the wheel off with a petrol disc cutter.

Exactly like the one I had Olly, a nightmare

Wheel nuts
Went to have 2 new front tyres today (Sat) - same problem, fitter could not undo both wheels. Gave the studs a good soaking in release oil and will take it to my local garage Monday. If they do snap (which going on my present luck with this car they will) at least its in a garage and not a tyre fitters so hopefully he will have extracters etc.

Poor you, I had the same crap last year and I ended up cutting my wheel off (lucky they weren't my Brabus ones otherwise i'd REALLY be in tears)
Cutting the wheel off is the easiest but definitely last resort option.

a solution I found that worked in the end (from another member) :
use a breaker bar to put tension on the wheel bolt, just enough but not to much to snap them.
with a good heavy hammer, hit the head of the breaker bar several times.
The shock of the hammering and the tension on the breaker bar will cause the bolts to become loose.
Extractors will not get anywhere near getting the bolts undone.
If the bolts are the ones with the long shank, get them replaced ASAP with the short shank version and you will not have this problem again. Also make sure that the muppets at the tyre fitters actually torque them up to the correct value, as over torquing is the cause of this.
BTW. I have a set of the short shank bolts if interested.

Update.
Finally sorted. My local garage did manage to release the studs on one wheel - the other no chance, 3 snapped. They tried drilling them out but the drills wouldn't touch them. The next stage was to remove the wheel and hub together and take the whole lot to a local engineering company who machined them out. Unfortunately they couldn't save the hub so that had to be replaced.
Anyway now sorted and all wheel studs at correct torque. The eejits that fitted the tyres in the first place have now cost me more than the cost of the original tyres. Perhaps we should all start a national campaign to insist that tyre fitters torque up to manufactures recommendation. That of course presuming they have a torque wrench on the premises.
