I'd like to put in a coach light just like the one below on the other side of the garage. The garage isn't finished, so the wiring will be easy. But I'm not sure how to cut through this thick stone facade to put in an electrical box. What tool would be best for this job?
Go to Home Depot or Lowes or any construction retail store and ask for a "masonry hole saw" that you can put in an electric drill. You can buy any size you want. I checked with my local Home Depot (on line) and got prices of about $25.00 for a 1" and up to $60.00 for a 4-1/8". They can be used for wet or dry drilling in almost any masonry surface. I have used them for cutting holes in both brick and concrete.
