You say oxidized, so I assume the bolt is stuck and twisted off trying to get it out.
If that is the case, chances are the end result will be drilling it out.
There are many methods to do this. The object is to drill STRAIGHT and exactly in the CENTER of the bolt!
If the part can be removed and put in a mill or drill press, that is the best method. If not, sometimes a drill fixture can be used. That is a block of steel with a known straight hole can be clamped or bolted over the broken bolt, then drilled through the fixture to keep the hole centered and straight.
The object is to drill all of the bolt out, leaving just the thread in the hole. Use a tap-drill chart to determine the size drill to use. Trying to use an easy out will only result in a broken easy out, that will have to be removed with a carbide end mill, a much worse situation. Easy outs have their place, but only in a bolt that was sheared off or over torqued, in other words, the broken bolt needs to be somewhat free to come out, not rusted, corroded or seized in the hole.
Once the center is drilled out, the remaining thread can sometimes be peeled out, but typically it is best to tap it out. If the hole is damaged, a thread repair coil can be used to restore the original thread, or drill and tap to the next larger size.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
