There is a rusted, broken off screw stuck in my overflow drain. Ive tried screw extractors but it’s impossible to drill inside of the screw because it has a conical protrusion right in the center where the sides have rusted away. I’ve now broken multiple drill bits trying to get this out. It also doesnt help that the plastic holding it there has give. So i’m pushing the plastic away from me instead of drilling into the screw.

Is there anyway to get rid of this without replacing the pipe?
