Southwire Hole Making
When your project requires a circuit or feeding wires through a piece of steel, a Southwire® hole making tool will help. Often called a knockout punch, stud punch, panel punch or chassis punch, this tool works with a die and screw, removing material and making a perfectly round hole. Some Southwire knockout tools use manual drive systems, while others use a ratchet or hydraulic system. There are single tools available as well as complete sets that provide multiple punches and die sizes, such as ½-inch or 2-inch options.
When using a hole making tool, avoid holding onto the material you’re cutting through with your hands. For your safety, clamp down the material securely. Most Southwire stud punches cut through 10-gauge steel, plastic, fiberglass, aluminum and stainless steel. Some may require a predrilled pilot hole, however. Choose the draw stud or screw you’re using first, and make a pilot hole large enough for this stud. Place the die on the draw stud, put the stud through the hole, then screw the Southwire knockout tool on the back of the material. When using a manual punch, a wrench or an Allen key is necessary for tightening the screw. Ratcheting wrenches and hydraulic Southwire hole making tools make cutting through the material a lot easier, but they are bulkier.
Unlike Southwire pliers, which generally make straight cuts from the side of a material, the knockout punch lets you cut a circle in the middle of it. Some punches even come in different shapes, such as hexagons or squares. If your work keeps you on the go, consider purchasing a Southwire stud punch set with its own carrying case to make carrying the punches as well as your other Southwire cutting tools easier.
