A Step Drill Bit is a versatile, cone-shaped tool designed to drill multiple hole sizes without the need to change bits. Featuring a series of graduated cutting edges, it allows for seamless drilling through various diameters, making it ideal for tasks involving thin materials like sheet metal, plastics, and wood. Beyond drilling, its design enables chamfering and deburring, providing a clean finish in a single operation. Commonly used in electrical work, HVAC installations, and automotive applications, the step drill bit enhances efficiency by reducing tool changes and ensuring precision. For optimal performance, especially when drilling metals, using appropriate lubricants is recommended to extend the bit's lifespan
