Review on Jiozermi Cutting Bi Metal Smoothly Cornhole by Craig Lovro

Received my hole saw today and set it on my drill press trying to cut through a plain piece of 3/4" plywood. This turned out to be quite difficult, as he wanted to burn more wood than chop, despite moving as slowly as possible. It took me 15 minutes of dedicated effort to get through, but I ended up with a nice clean hole and cutout. So I wouldn't recommend it if you want something that just works, it takes a little bit of time and effort - more than you can imagine for something that should be that easy.
