Redrill → It is formed from "re-" (meaning again) and "drill" (from Old English "drillan", meaning to bore or pierce). The word "redrill" means to drill again or to bore a hole anew.
Think of doing something 'again' ('re-') with a tool that 'bores' ('drill') into a surface — that's why redrill means to drill again.
