To drill a hole in metal, first use a centering punch to make a small indentation in the metal so the bit does not wander. Then clamp the piece of metal securely to a piece of scrap wood. When the bit penetrates to the other side, it will have a tendency to grab the piece and spin it around at high speed. This can be dangerous, especially if it catches a finger, and thus, it is very wise to clamp it securely so that the piece stays put. Once it is clamped, put on a pair of safety goggles and then place the tip of the bit in the indentation made with the centering punch and hold it perpendicular to the piece (that is, if the piece is perfectly horizontal, the bit will be perfectly vertical). If the bit is not perpendicular (straight in), it will have a greater tendency to wander.
