Drill and tap it for what?
Yes, but you have to drill and tap.
For a cut tap the correct drill size is a #17 drill, which has a diameter of .173 inches.
Common references list the tap drill for a #12-24 screw as #17 or .173"
It is not a drill bit, it is called a Tap. You drill a hole slightly smaller than the Tap and then screw it into the hole.
You can use a small drift to tap it loose OR drill it out.
