Oh yeah, sent tip of spade bit up thru formica countertop. Once my crew was using our coring drill to core a 6" hole in a paved area behind Aloha Air Cargo, so we could put in barrier posts around our equipment. They drilled thru a rigid conduit feeder to the meat storage locker. It was Friday afternoon. I got the call from the field around 3:30 pm- quiting time. I had to go out and fix myself after hours so the 60 k worth of frozen meat stayed frozen.
