DEWALT Power Tools Extreme Step Drill Bit 20-34mm DT5031-QZ

The DeWalt Extreme 2 Metal Step Drill Bit is a professional-grade step drill designed for drilling and enlarging holes in a wide range of metals and plastics on site or in the workshop. Featuring a titanium coating, this step drill bit offers enhanced wear resistance and corrosion protection — delivering up to twice the service life compared to standard black oxide alternatives. This makes it a practical, cost-effective choice for contractors and tradespeople who rely on consistent performance across repeated use. The optimised geometry helps the bit penetrate material faster and drill with precision, reducing the risk of walking on sheet metal and thin-walled materials. The anti-slip 10mm shank provides a secure, stable connection in the drill chuck, supporting accurate results even in demanding conditions. Suitable for ferrous and non-ferrous metals, stainless steel, aluminium, and plastics, this stepped drill bit is ideal for electricians, fabricators, and general contractors working with thin-walled materials up to 3mm thickness. With multiple hole sizes incorporated into a single bit, it reduces the need to carry multiple drill bits to site.
