I would try the easy out. Get the correct size easy out. Try to get a good placed center punch in the middle of the bolt. Then start with a small drill. Try to get the drill as straight as you can. A second person helping is good for this. Then slowly work you way up to the correct size drill for the easy out. Be very careful. Work the easy out into the hole. Then gently try to turn the easy out and see if the bolt moves. If not heat the area around the bolt and try again to turn it. Before you start put lots of oil or lubricant on the bolt and let it soak in. The other way is if you have a welder weld a nut to the top of the bolt. You have to be a good welder to to this. Place the nut on the bolt and weld in the center of the nut. The heat from the weld helps losen the bolt, then just turn the nut with the wrench. If none of this works, go to plan B.

X2, on the be very very careful with small drill bit. In fact I would not use smaller than 1/8. But look at the size needed for the proper easy out and then figure out what size bit to start with.

I agree with has been. I would try to spin it out with a sharp center punch first. I forgot about that method. Just angle the punch at the edge of the top of the bolt and tap it in the correct direction. Rightsy tightsy, leftsy loosey. If the god of the gear heads is in a good mood and likes you it should just start to move, and you can work it out far enough to get a grip on it with the pliers.

Good Job!!! I can see that the hole you drilled was as close to the center of the bolt as you can be. That is the hardest part. Next time tighten down till just before it breaks, then back off 1/2 of a turn. LOL. The gear head god was smiling on you this time. By the way. Plan B was to drill it out, then helicoil. But that is for another day.
