Review on 🔧 Hordion Bi Metal Drilling Tools for Cornhole Plasterboard Cutting: Ultimate Hole Saws & Accessories by Mike Travers

This is a good hole saw but if you need an 8 inch hole this won't work. It's 7 7/8 inches. Some fasteners require 8" and will not fit in a 7 7/8" hole. I don't know why they are advertised as 8" unless they cut an 8" hole. This is a very heavy duty saw blade and requires a lot of energy to operate. I test cut a hole in very thin wood and it was too small for my lamp. It took a long time to even cut this hole. Hole with copy saw and 10 tooth/inch blade.
