I'm installing a range hood in my kitchen with a 7" round exhaust duct to the outside.
The exterior covering on my house is brick. I should also note that this is 1920's vintage brick and the joints, etc. are somewhat fragile. Any method of putting a hold through has to minimize impact that could knock loose more that I want to.
I previously had to put a smaller hole through for a bath fan exhaust. I used a hammer drill and drilled a series of 1/2" holes as close together as possible around the circumference of the hole. I then used a chisel to gently "connect the dots" to finish up the hole. It worked, but was very time consuming.
This method would also work for the 7" hole, but will take a lot longer with a lot more little holes to drill to cover the larger circumference.
Does anyone have a better way? I only have one hole to do, so I don't want to buy an expensive tool to do it. I probably would spend $30-50 to rent/buy a tool if necessary just to make it go faster.
Thanks,
Joel
