Unless you have an extensive mortising setup, drilling square holes is a tough task that usually involves chisels. That’s where the Quadsaw comes in. Unfortunately, this is designed to work only with drywall, but if you’re an electrician, you’re pretty stoked because this tool will take a process that used to take several steps and whip it out in one go. It leaves a nice neat hole and can be adjusted to do double or single receptacles. You can pre-order now for about $250.
