Introduction to Step Drill
A step drill, also known as a step bit or conical drill bit, is a specialized drill bit with a series of steps of increasing diameter along its length. This design allows the bit to drill holes of different sizes without the need to change bits, making it highly efficient for tasks such as drilling holes in thin materials, creating multiple - sized holes in a single operation, and deburring. Step drills are commonly used in metalworking, electrical work, plumbing, and automotive repair industries. They are available in various materials, such as high - speed steel (HSS), cobalt - alloyed HSS, and carbide, each offering different levels of hardness, durability, and heat resistance.
