Stud and Keyway Punches
A stud punch provides a quick way to create the holes that enable you to run wires and cabling through metal studs without having to pre-drill. A keyway punch (AKA keyway nibbler or nibbler punch) is used as a fast way to create round holes or raised tabs in a variety of materials for push button switches, rather than sawing and filing. Items vary by what gauge of steel they will punch through, as well as hole size, handle type and other considerations. Manufacturers include Greenway punch and others.
