I went with a 4-inch hole saw over a 2-inch for a tricky exterior wall pass yesterday.
The bigger cut gave me room to get my hand in and guide the cable, which saved me from having to come back with a fish tape. What's your go-to for tight spots in old plaster walls?
Did you guys see that old electrician trick where they shave down an old broom handle into a fish stick? My buddy swears by it for those plaster walls.
