I busted off a bolt head in my elliptical machine, so I tried to remove the remaining part by drilling a pilot hole and then using a #2 screw extractor. I drilled a little over a 1/4" before my cobalt bit gave out. Then I tapped in the screw extractor and tried turning out the bolt, counter clockwise. It never seemed to really bite, and soon it just turned freely. Any suggestions?
