What is a Step-Drill Bit?

The Basic Structure of Step-Drill Bits

A step drill bit, also known as a unibit, is a conical-shaped cutting tool featuring multiple cutting edges, each with a different diameter. The cutting edges are arranged in a stepwise fashion, from the smallest at the tip to the largest at the rear.

The main purpose of a step drill bit is to drill multiple-sized holes using a single bit without needing to change bits for each size.

Materials and Applications of Step-Drill Bits

Step drill bits are commonly made from high-speed steel (HSS), cobalt, or carbide, depending on the material to be drilled and the desired performance level. They are ideal for use on thin, soft materials like sheet metal, plastic, and wood and work best for enlarging existing holes.
