Need to drill only to a certain depth in wood or other material?  Wrap electrical tape around the bit two or three times, beginning at a distance from the bit’s tip equal to the depth you want to drill.  You will be able to see and feel exactly where to stop.  Don’t use too much pressure, though, or the tape will slide upward and the bit will go in deeper than you want.
