You likely have the same "bricks" that I do which are actually colored concrete
in the shape of a brick. I used (one) masonry bit to install an outdoor
electrical outlet on my sister-on-law's house. She has "real" bricks and the
bit went through them like butter. Armed with that success I decided to do the
same on my own house. Took me three brand new bits to make two holes for my
screw anchors. All were ruined by the process.
What you need is not a better bit (though there might be one), but rather a
hammer-drill as opposed to a regular one.

No. The bit isn't the problem. The drill is. For masonary you need a
hammer drill. A hammer drill acts like an impact and chips forward through
the brick as you drill . Suggest seeking out your nearest rental company.
I think what you have is a real fired brick that is very hard to drill
regardless of having a hammer drill or not. I would suggest drilling into
the mortar instead of the brick if possible. I ran into this when I was
installing lighting on an 100+ year old house. The mortar drilled like
butter and took the rawl plug and held very well.

I agree with the above statement.
