I would tape the grill up really well making sure the tape lays smooth and cut with the dremel threw the tape. Should help to make sure the chrome doesn't strip off. Do the same thing if your drilling holes in something painted and it helps not ruin the paint... It's not 100% perfect but definitely better than nothing. I would try to find a scrap piece and try it first to see how it works
