STEPPED DRILLING BITS

Step drill bits are designed to enlarge a hole as the bit drills through the sheet metal. Each step on the bit is larger in diameter than the step before. Smaller step drill bits are self-starting and no pilot bit is required to start the hole. Unibits and step drills work exceptionally well on sheet metal.
