It is hard to believe how true this is until you start to get to really esoteric stuff. Example: I have electronic mortise locks (historic house with very custom doors that used mortise locks, replacing doors would be ... remarkably expensive. There are two doors i replaced with non-mortise locks by filling the cavities with marine epoxy, but wife really like the look of mortise locks on the others). There are a very small number of wireless mortise locks, all of which are garbage and look ugly to boot. The way these are electrified is either: 1. Wireless power transfer from the strike side - this is complicated and only works sometimes. or 2. Drilling a hole all the way sideways through the door and running a wire inside the door, using special hinges with embedded wires to transfer power through the hinge, and then connecting that all to a 24v supply somewhere. I have the tool necessary to do #2, which will properly drill a straight hole 36 inches deep horizontally into a door with perfect alignment. In part because the tool is as expensive as paying someone with a tool to do it for you, so i might as well own the tool. Doing this without the tool, I imagine even with the right set of bits, you would screw it up probably 99% of the time.
