A step drill bit is a type of drilling tool used to create holes of different sizes in various materials. It is designed with multiple cutting edges that gradually increase in diameter as you drill deeper into the material. This allows you to create holes with different diameters without needing to switch between multiple drill bits.
Step drill bits are commonly used in metalworking, woodworking, and other applications where precision and versatility are required. They are especially useful for drilling holes in thin materials or enlarging existing holes. The stepped design of the bit helps prevent the material from binding or splintering as you drill, resulting in cleaner and more accurate holes.
