One size bit cuts many sizes
The "one size" description seems to refer to the single step that is labeled and is wider than the others. But you can drill any hole from about 1/4" to 7/8" if you control it and if the material is thinner than the step length. I've used it on 20 gage steel at several sizes. It works well.
