How do I install an electrical box in a concrete/brick wall?

Question by Woodpeckerppa: How do I install an electrical box in a concrete/brick wall?
Hi everyone,
I am wondering if there were any special tool to make a square/rectangular housing in a concrete/brick wall for an electrical box? Generally we can drill a round hole using a masonry bit, then there should be a tool to convert that round hole into a housing for an electrical outlet. I remember seeing someone who does it with a special tool that is attached to a hammer drill/jackhammer.
It would be great if anyone can point me to the right direction.
Thank you in advance.

You could use an angle grinder with a masonry blade on it or a diamond tipped blade would also do the trick don’t use a jackhammer as you could upset the rest of the wall and cause cracking and you could end up with a lot of repairs to do.
