Quadsaw
Drills are built to make round holes. Light switches, power outlets, and other utility plates are square or rectangular. The Quadsaw makes the two compatible. It attaches to your drill like any other bit, but uses four specially-designed blades to slice through drywall in as little as ten seconds, cutting single or double outlets with ease. It has a built-in height guide and spirit level to keep your cuts tidy and consistent, and is made from durable materials that will keep it working job after job.
