A step drill bit (or Unibit) is a conical-shaped drill bit that features a series of gradually increasing cutting diameters, or "steps." This design allows one bit to drill multiple different hole sizes.
A 6-piece set typically covers a very wide range of hole sizes, often from 1/8" (3mm) up to 1-3/8" (35mm), spread across the six bits.
