Step drills are conical bits ideal for drilling various hole diameters in thin materials like sheet metal, plastic, or wood. Each step increases in size, allowing clean, precise cuts without changing bits.
Yes I'm InterestedA Step Drill, also known as a step bit, is a specialized cutting tool designed for drilling and enlarging holes in thin materials such as sheet metal, plastic, aluminum, brass, and other soft materials. It features a conical shape with a series of gradually increasing diameter steps, allowing users to drill multiple hole sizes with a single bit. This unique design eliminates the need for frequently changing drill bits and ensures precise, clean cuts with minimal burring.
Step drills are commonly used in electrical work, panel installations, automotive jobs, HVAC systems, and general metal fabrication. They are ideal for creating clean holes in junction boxes, control panels, and metal enclosures. Most step drills come with laser-etched size markings beside each step, making it easy to monitor the depth while drilling.
Made from high-speed steel (HSS), cobalt, or titanium-coated materials, step drills offer excellent durability, wear resistance, and heat resistance during continuous operation. Their self-centering tip design helps in easy starting without the need for a pilot hole. Step drills are compatible with standard handheld drills and drill presses, making them a must-have tool for professionals and DIY users alike.
