The screws are (I'm guessing) about #10 self tapping. The I-beam frame is tapered thickness but I'd guess where the screws go through it's about 1/4" thick steel.
#10 thru 1/4" steel? Not likely. That's too thick. 1/8" may be?
Anyway, you either punch out the old screw or drill it out. But as mentioned, some sefl tappers are harder than your standard screws.
Masonry bits wont touch metal...doesnt matter what they are made of...forget that.
Look for screw removal kits that come with a drill bit, or drill/removal tool combo bit.
Last resort, if you insist on not making new holes with new screws (which I dont understand) buy couple 1/8"-3/16" carbide ball end mills from McMaster. They will get that screw out, but it will still be tricky alignment.
