A HSS Step Drill Bit Set is a set of high-speed steel (HSS) tapered drill bits designed to drill multiple hole sizes with one bit. Each “step” on the bit corresponds to a larger drill diameter, so you can progressively drill holes in sheet metal, plastic, wood, and thin materials without changing bits many times.
