Product Description
The Greenlee 730BB-1-3/8 knockout punch unit is a top - notch tool for your punching needs. It features a hole size of 1 - 3/8 inches (34.9 mm). The punch unit comes with a punch (3205AV), a die (3206AV), and a draw stud (249AVBB). It can handle mild steel up to 10 gauge (3.5 mm) and is suitable for punching mild steel, aluminum, fiberglass, and plastic. You can operate it with battery - powered, hydraulic, ratchet, or manual drivers. When using battery - powered, hydraulic, or ratchet drivers, you only need to buy the punch and die as the draw stud is part of the driver kit. The hole size corresponds to the outside diameter of US conduit sizes. For example, a 1/2 - inch conduit size punch creates a 7/8 - inch hole. It also supports Pg Sizes (European standard pipe sizes) and ISO Sizes (International Standards Organization pipe sizes). These round standard metal punch units are complete, including punch, die, and draw stud. They are designed to make clean, fast, and accurate holes when properly assembled through pilot holes and used with the appropriate drivers.
Using the Greenlee 730BB - 1 - 3/8 is easy. First, decide which driver you'll use - battery - powered, hydraulic, ratchet, or manual. If you're using a battery - powered, hydraulic, or ratchet driver, you don't need to worry about the draw stud as it's part of the driver kit. Just make sure to buy the punch and die. For manual drivers, you'll use all the parts of the punch unit. When you're ready to punch, properly assemble the punch unit through the pilot holes on the material you want to punch. This could be mild steel, aluminum, fiberglass, or plastic. Make sure the material is no thicker than 10 gauge (3.5 mm) mild steel. As you operate the driver, the punch unit will create a clean, fast, and accurate hole. Remember, the hole size is related to the outside diameter of US conduit sizes, so check the size requirements carefully. When it comes to maintenance, keep the punch and die clean after each use. You can use a clean cloth to wipe off any debris. If you notice any signs of wear, like dull edges on the punch or die, it might be time to replace them. Store the punch unit in a dry place to prevent rust and damage.
