The conical powerhouses called Step Drill Bits, or Unibits, are amazing. Drilling through metal, wood or plastic, even holes over an inch in diameter is a breeze with a step drill bit. Their massive presence makes short work of metal, even car frames. So unless you need a deep hole of uniform diameter, the Step Drill Bits should be your first choice.
