[HIPPO]

You don't drill out the screw, you just remove the plug that covers the screw. You take a small drill bit like 1/8" or close to it and drill slightly into the plug (make sure you do not drill thru it) just enough to where a sheet metal screw will hold in the hole you just drilled and then you pull on the screw with a pair of pliers so as to remove the plug.

Some of the info is old, but it should give you a better idea.
