Core Drilling is commonly used to create round openings in concrete, stone etc. to install plumbing, HVAC, electrical, dowels, posts through concrete etc.  or for obtaining test core samples. We can core-drill anything from 1/2″ to 48″ in diameter.  Depth is not a problem, we have the ability to drill at very deep depths…Steel reinforced slabs and walls, brick, block, stone and asphalt can all be core drilled by Big K.
