installation - How do I cut a brick fireplace hearth to allow for a ...

I am attempting to cut a small piece out of the brick fireplace (already in place) to allow for the expansion of the floating laminate flooring that I am installing. I don?t want to just leave the flooring short of the fireplace (I think this looks very unclean), I don?t want to put any molding across the front of the fireplace (I also think this would look terrible) and I don?t want to fill it with caulk. I also considered purchasing the end cap pieces, but I didn?t think having the trim going in a difference direction than the flooring would look very nice (fireplace is not parallel to the flooring, see image at the end).

I bought a carbide blade (said it would cut through brick on the packaging) for my oscillating tool. When I went to cut the brick, it barely put a dent in it. So I?m not sure if my oscillating tool (1.8A) is just too weak (had it cranked up the whole way) or if I need to go with a grinder and a diamond blade or some other tool.

The tricky part is, the fireplace is in the corner of the room, so I would need something that would get into a tight place. So before I sink any more money into trying things, I wanted to see if anyone had any advice on how to cut this. I was also thinking after making the cut, I would need to somehow chisel out the pieces at the bottom as well (maybe they would break off?).

Any advice would be appreciated.

Here is a zoomed out image if that helps (No I didn?t put in the off center fire place, it was like that when I bought the house).
