Step Drills
Step drill bits, also known as cone bits or unibits, are specialized tools designed for creating holes of varying diameters in a single pass, featuring a conical shape with multiple stepped cutting edges. This design allows users to drill different-sized holes without changing bits, making them efficient for applications that require multiple hole sizes. Commonly used on thin materials such as sheet metal, plastic, and wood, step drill bits are ideal for HVAC, automotive, and electrical work. Typically made from high-speed steel (HSS) or cobalt for durability and heat resistance, these bits often include a pilot tip to ensure accurate hole placement by preventing the bit from walking.
