I am in the process of attempting to install an outside switch for a radon mitigation system. However, I am unable to drill through the remaining part of the block wall. I have an M12 Fuel hammer drill and a carbide drill bit. I imagine something is in the way but what? If it was concrete in the floor I would guess rebar. The first part went through like butter.

I don't know what it is but take the hint. Find another place to drill. It could be a plate protecting something, or a pipe.

Yeah, I'll try drilling somewhere else. I wasn't too specific but given the location of that wall, I know for a fact there is no kind of pipe or anything in there.
