Review on 🔐 Ryobi A99DLK4 Wood and Metal Door Lock Installation Kit for Effortless Deadbolt and Lockset Installation by Tony Trotter

Before buying, read the reviews on this tool. Apparently many had difficulty removing the cylindrical cutting wheel from the mandrel when switching between two different bit sizes. I replaced all the doors in my house with solid oak paneled doors, so I bought a separate frame for the second hole saw. First I drilled half a hole for the bolt and then loosened it from the drill and left it in the door. This allowed me to then drill a hole for the locking mechanism, using the smaller hole saw as an anchor to hold the tool in place. After the big hole was drilled, I finished drilling the smaller hole. Fits perfectly in all my doors. The bits wear out over time, but I haven't noticed any wear on the tool itself after 18 doors.
