Plenty of wrong answers.Step drilling is considered bad practice.Corners will break off the drill bit because of the high load on the corners.A drill is apt to catch and break.I have to drill a lot of 3/4 and 7/8 in 1/2 inch steel with a small drill press.A sharp drill and oil helps the job.A friend broke my 5/8 drill trying to open a hole up to 3/4.
