step drill

A step drill is a specialized drill bit used to create holes of multiple diameters in a single operation. It's commonly used in metalworking, woodworking, and other applications where precise and incremental hole sizes are needed. Step drills are particularly useful for enlarging existing holes or creating holes in thin materials. They are versatile tools that can save time and effort by eliminating the need to switch between multiple drill bits or hole saws to achieve different hole sizes. They are often used in applications like sheet metal fabrication, electrical work, and plumbing installations.
