Maybe try something on a scrap and see if your skills and available tools are going to give you the results you’re after.
If all you have is a drill, maybe make a drill guide from some wood or plastic, and then clamp that to your metal. Use cutting oil and go slow.
If not, then do what was suggested in post 21…

Fortunately I found smaller pieces but large enough for me in their debris box.
- Cut out the entire area, and cover it with a pre-drilled piece of steel (or aluminium) sheet from inside or outside.
