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.

Rebar is used in hollow block wall too:
I’d remove one of those circular knockouts at the back of the wall box to drill an inch to the left or right.
Huh, the more you know. I’ll try that out tomorrow. Thanks
Might be rebar or other reinforcement in the wall. See if you can shine a light on the hole and see what you are hitting. You might have to vacuum or blow the dust out first.
