RE: Diameter of borehole?
3.5" O.D. solid flight auguers
3.25" I.D. hollow stem auguers
or
4.5" I.D. hollow stem augers.
The O.D. on these hollow stem augers about about 8" and 10" respectively.
There are also larger hollow stem auguers.
For deeper holes you have mud rotary drilling with bits starting at about 4" diameter and going up.
