I’m thinking this will be a long shot, but looking to borrow (or find a place to rent) a concrete coring machine that will have between an 8-10" bit to core through a 4" slab of concrete. Appreciate any help! ---

Between 8 and 10 inches? So you don’t need a precise hole? ---

dont put the posts in the concrete, they will rot quicker, get 3 of the brackets that you sink into concrete for bolting posts to, that way the wood doesnt absorb moisture from the damp concrete ---

United Rentals only had a 6" and a 12" bit in stock… Any other places that rent coring machines? Or anyone on here own one and want to make some quick $$$? ---
