very very sharp drill bit?

Give it up and take it to an automotive machine shop. Some things are better left to the pros. Unless, of course you're bound and determined to keep on until you have destroyed any hopes of saving the rim.

the amount of money it would cost to buy that bit would be worth more than the rim is worth.meaning your best bet is to buy another rim.easy outs are a tough carbide type of metal.that's if you bought or used a good quality one.but from experience,can you drill the opposite side of the hole?maybe a little bit bigger than the bolt that is broken and thread it out that way?ive done that before.just a thought.good luck.

You need a diamond bit to drill an easy out. Easy-outs are incredibly hard. Diamond drills must be run wet or they'll burn up. Even if you drill the easy out, it still is stuck; I would try and chisel the easy out piece loose, if there's room to do that. The broken stud is junk anyway, so try and un-wedge the easy out it from where it's stuck in the stud. Good luck.

The Tungsten carbide should do it, maybe yours is dull, or try a titanium coated one. Also you can drill a smaller hole for a pilot hole and don't drill with too fast of rpm's, let the bit grab. And use some cutting oil, even wd 40 if you have it.

in all honesty a torch would be best

but try a high carbon steel

or explain the problem to the boys at auto zone im sure theyll know

goiod luck

Bummer, I hate when stuff like that happens. Imagine doing that to a head bolt. Your best bet is to take it to Napa and have them machine it out.

you need a pro for this. some of the motorcycle guys run into these type of problem more so than than car mech
