HSS is an acronym for High-Speed Steel. These drill bits are extremely hard-wearing and particularly well-designed for drilling into metal surfaces. They are much more resistant to the heat generated from high-speed operation. Our fastest-selling sizes are 2 millimeter, 2.5 millimeter, 3 millimeter, and 3.5 millimeter, as these sizes are commonly used for pilot drills.
