How long does it take to core a hole?
Depends on the size hole and the thickness of the concrete. For hoes 1 1/2″ and under, using a good percussion masonry bit in a hammer drill, it would only take 60 seconds or less to get through a 4″ concrete slab. Larger diameter holes require the use of a core drill. You can rent them at a rental center.
