What is a "step drill bit"?
A step drill bit is a type of drill bit designed to create holes of different sizes in a single pass. It has a cone-like shape with steps or gradual changes in diameter along the length of the bit. Step drill bits are commonly used for drilling through thin materials like metal, plastic, or sheet metal, as they allow for multiple hole sizes without needing to change bits. They are especially useful for tasks like drilling holes for electrical fittings, pipes, or mounting holes in various materials.
