What is step drill bit?
A step drill bit can be used to drill a range of different sized holes with a single bit. Since each bit size drill holes less than 1/4″ deep, a step bit is mainly used for drilling thin material such as sheet metal.

To make it easy know how deep to plunge the bit for the right sized hole, wrap a piece of masking tape around the bit at correct hole size.

Step drill bits work exceptionally well on sheet metal. They can be used on other materials as well, but you won’t get a straight smooth-walled hole in solid materials thicker than the step height. Step drill bits are incredibly useful for one-step drilling operations, but they’re not suitable for all operations.
