Description
Product Description
This versatile 4 mm–20 mm step drill bit is designed to drill multiple hole sizes with a single tool—ideal for sheet metal, aluminum, plastic, and thin steel. Its stepped design eliminates the need to swap bits, while the spiral flutes and self-starting tip ensure clean, burr-free holes every time. Crafted from high-speed steel (HSS) and finished with black oxide or optional TiN coating, this bit is built for longevity and performance in both professional and DIY settings.
