I have a Bell Tec Hydraulic Auger and I need a larger bit all I have currently is a 2" puff drill for putting in T post. What size is best for all around wood/metal pipe fence post holes. Also I need to use it to drill 48, 2' deep holes in mostly solid rock to sink piers for my new house I intend to use .60 pressure treated 6" x 6"s since nothing else seems to be available or reccommended for this purpose. The point of the question is I can only afford one more bit right now so it needs to do everything, the bit cost around $1,100 I'm thinking a 10" but I welcome everyones input.
