Step drills are versatile tools designed for clean, precise holes in a wide range of materials, including metals, plastics, and composites up to 4 mm thick. They allow a single bit to drill multiple hole sizes, making them ideal for enlarging existing holes while reducing tool carry. MILWAUKEE® step drills feature RAPID STRIKE TIP™ technology for accurate starts without walking, optimised two-flute geometry for faster, smoother cutting, and relief-ground steps that drill and deburr simultaneously. Built from custom-engineered steel with a black oxide coating, they offer up to four times longer life and are specially designed for high-speed cordless drills, making them durable, efficient, and reliable for trades such as electrical, plumbing, metal fabrication, automotive, and maintenance work.
