Review on 🔪 Dribotway Bi-Metal Cutting and Drilling Fiberboard by Anthony Lopez

I bought a 110mm bit to cut holes in the drywall to install 4 inch led lights. The hole diameter was perfect. Some installers recommend using a rear drywall hole saw for a smoother cut, but this is not possible with the mandrel of this saw. I started the drill slowly and held it carefully and for the most part the hole was even. For my application, this hole saw was a good value.
