I am looking at renting a handheld coring drill and 4 " coring bit to
drill some ( about 12 ) weep holes in a 8" poured retaining wall (
all easy access) .

If you just want weep holes on an existing wall, why bother making them
4" in diameter? Why not just get a rotary hammer and make 1" (or even
less) holes?
