Chuck,
In Maryland, where brick veneer construction is common,
all tool rental stores have the equipment needed to drill
a large diameter hole in brick, concrete block or concrete
walls
Hopefully, tool rental companies in your area will have the
same equipment. If not, talk to an electrical or HVAC
contractor, they should be able to point you in the right
direction.
I drilled a hole large enough to insert a 3 inch plastic pipe
through the wall. It makes a very clean installation, on
both sides of the wall. A smaller pipe may meet your
needs. In my case, I needed five of them...
73!
