Its not important so don't spend to much time searching Ollie, I was just interested in how such a tool worked.
Thanks for trying anyway.

If it is as tight as it sounds the I would not contemplate an "easy out"as this will probably break.
I would use a heavy hammer and shock the bolt on the head with a few hard blows. Do you have the tool for the lockbolt? If you do and if it still grips the bolt then this should loosen the bolt after a few attempts. Dont put on so much weight as to round the bolt. Also ensure you have the vehicle jacked up to take the weight of the bolt!!!

I've got one off by welding a large bolt on to it. The heat also helps to expand and free it off too.
I need to revive this thread again. We have tried the eazy out option, didnt work. We got a more powerful drill and managed to drill upto 8.5mm and its still very much on there, the wheel just will not come off no matter how hard we hit it.
This locking nut is one of the toughest i'd ever seen, it just wont give way.
I would've thought that 8.5mm would've affected the thread on the bolt by now, but its so damn tight it wont budge, not by conventional methods or by force. We want to avoid the welding route as none of us are any good with welders and we dont have access to one.
I can try to take a picture of it soon to show you all what it looks like if it helps. But there must be something to get this off...

The only other thing I can think of is to get some of the spray plumbers use for freezing pipes, spray it on the nut and then try and split it with a cold chisel and club hammer.

You can buy a stick welder for £40 - your welds dont need to be pretty and you'll have it off in 30 minutes.
Much better than all your fighting with this.

Bigger drill bit - sooner or later there will be no thread left and it will just fall off

speak to the likes of kwik fit or your local indi tyres place - they will have the proper socket. IIRC you bray it on with a club hammer then wind it anticlockwise with a power bar, it has a l/h thread which grips harder the more you wind, my memory tells me it really needs to be whacked on hard before you turn it.
£20 to your local tyre fitter for Xmas?

If this is just a 'normal' locking wheel nut, then what you need is a 'bolt extractor' It works on the principle of a screw extractor, but the spiral tapered thread is on the inside of a socket, which fits over the head of the bolt. Tunes Engineering Service Ltd., 506-509 Ipswich Road, Slough. SL1 4EX Tel :01753536811 Have probably got these, but I can't seem to get on their website at the moment. I have the feeling that this is what Ollie was talking about. Here's one example that I found
I had the same problem x4 a couple of years back when I bought my 190E 2.6 and it turned out the previous owner had lost the key to the locking bolts .
I tried hammering on a socket over the end of the bolt and this was enough to loosen three of them but , of course , there was one stubborn one .
I resorted to drilling , I quickly found the bolts were made of very hard metal which was very good for wearing down HSS and titanium coated drill bits - I did manage to get a pilot hole drilled centrally which was a good start . In the end , I went down to B&Q and found they had a Bosch bit which was designed for metal , masonary and all sorts . I found that putting this in on the hammer setting and just battering away was the quickest method at the expense of both the bit and the bolt - it didn't take long to drill enough out to get my largest 'easy-out' in and thankfully the bolt came out .
Here's the culprit

I think that sort of drill bit is called a Piranha at B&Q ?
