What size do auger bits come in?
Auger bits are produced in metric sizes ranging from 6mm to 25mm and imperial widths ranging from 1/4″ to 1″. Compared to other types of drill bit, auger bits can be considered to be quite long.

Which is better spade bit or auger bit?
Spade bits are much less efficient at clearing out boreholes than auger bits and leave a much rougher finish. Spade bits also require more downward force to use than auger bits, making holes much easier to drill with auger bits.
