"This is a great hole cutter for electrical boxes. Quite often the knockout locations on a larger piece of electrical equipment such as a circuit breaker panel aren’t where you need an opening. Perhaps your wiring or conduit would work better and be cleaner if it entered the box in a different location. It is usually allowable to drill additional holes in these panels as long as they don’t interfere with other components or interior parts and it is done in a “workmanlike manor”. Actually, many electrical panels don’t even come with knockouts at all, and the electrician is expected to cut them in where needed.\r\n\r\nThis 1-1/8 inch size Milwaukee hole cutter is the perfect size for 3/4-inch EMT fittings, NM cable clamps and other fittings that are designed to fit the “3/4 inch” hole into electrical boxes and enclosures. The best part is that it works great. It is carbide-tipped, so it works fast and cuts a clean precise hole, unlike hole saws. Little if any filing is needed to remove burrs. It also works well for drilling holes in steel studs, since often there are no factory holes in the studs where you need to run conduit\r\n\r\nThe cutter portion of this tool is removable from the pilot bit in case it needs replacement or sharpening, and an allen wrench is also included for that purpose. It is also designed with a spring around the pilot bit to pop out the center slug. I would have liked to see this item contained in a box that was durable enough for long-term use and would protect it, with the speed chart permanently attached to the box. I take good care of my tools and expect them to last a long time, and a good storage case shouldn’t be too much to ask for the price. \r\n\r\nI found this cutter to be well designed, and should be a real time-saver as opposed to a traditional knock-out set. I suggest using it like a traditional hole saw and drilling straight to avoid binding, and don’t exceed the recommended speed. For most users with battery drills this will seem very slow, but I suspect going too fast would damage the cutter and create an undesirable cut."
