Review on 🛠️ MOKENEYE Bi Metal Fiberboard Drilling Cutting Tool by Ricky Cruise

This really speeds up cutting holes for LED lights in ceiling tiles. The only thing that confuses me is that when the cut was complete and the drill stopped, the blade continued to rotate through inertia and jumped off the mandrel. It also wasn't possible to use the saw backwards (a useful trick to start a cut just to gently break the painted surface of the tile). Maybe I assembled it wrong?
