Drill bits are used to make holes in a piece of material by removing material in a spiral cutting motion. General purpose and specialty drill bits are available, and as a whole, cut through a wide range of material. The type of material the drill bit is made out of, coated in, and some geometry factors will all come together to determine what sort of material it is designed to cut through.
