Outlining designs for a DIY steel skid plate.
Looking to put a formed counter sink into 7/64 inch thick (~2.77mm) metal flat bar. Countersink on the bottom (street) side, recessed against the chassis to match the existing countersinks on the chassis (on right side of image).
My plan is to drill 4mm thru holes and then use some sort of shaped punch to indent the outer rim of the hole to contour to the chassis countersink. I'm not a machinist by trade, so i'm not expecting to get millimetrically perfect results, but would this tool do the job?

I don't have a machine shop, so this would just be myself in my garage with some 2x4's, a 4mm drill bit, a mini sledge and the metal flat bar. Would that work well enough?
