The Milwaukee® #5 Step Drill Bit (Model 48-89-9205) is engineered for professional electricians and contractors who demand precision and speed on every job site. Designed to drill clean, accurate holes through metal and plastic — from electrical panels and junction boxes to conduit knockouts and sheet metal enclosures — this step bit eliminates the need for multiple drill sizes. The dual straight-flute geometry delivers up to 2X faster cutting with jam-free performance, while the rapid strike tip ensures fast, accurate starts with minimal heat build-up. Laser-engraved size markings keep you on spec without guesswork, and the 3/8" shank provides a secure grip in both chucks and impact drivers. The black oxide coating resists corrosion and works seamlessly with cutting lubricants — built to hold up through demanding Canadian job site conditions.
