Default Cutting a new window hole in a 4" thick conrete block wall - tool recommendations?

And then the top of the window hole falls onto your head leaving an
interestingly shaped hole and a crack all the way up the wall.

Rotary grinders in general make an insane amount of dust. Is there
any other tool that anyone can recommend? (I'm visualising something

Apparently, wet rotary saws make less dust - presumably it ends up as a
nasty wet slurry instead. You'd have to hire one, though.

If I had to do it with the tools I have, I'd tape everything up with
plastic, then use a 9" angle grinder to make a neat hole on the inside and
outside, and then join up those lines with an sds drill and chisel
attachment.
