Review on 🪚 HSS Bi-Metal Extended Arbor for Deep Hole Drilling by Nathan Akers

Good quality; well made and beautifully painted. The saw teeth are quite sharp. The included drill bit is also very good and interchangeable (held in place by a hex screw). - External doors. It worked great for that. As suggested on many YouTube videos, you should drill this type of hole on each side of the door (stop when the arbor drill first/straight into the opposite surface, then finish drilling on THAT side to finish the hole ; this helps control the pull -out "/split around the hole you just sawed/drilled. You want to minimize damage to doors and other machined or visible surfaces). I usually use cheap spade bits when drilling holes large diameter (in wood), but his hole saw makes excellent and accurate holes and is easy to control when working with solid wood.
