The Greenlee 730BB-1 is a top - notch round standard metal punch unit. It comes as a complete set including a punch, a die, and a draw stud. When assembled correctly through pilot holes, it can create clean, rapid, and precise holes. This punch unit is made up of a 87AV punch, a 35164 die, and a 00042 draw stud. It has a capacity to punch through mild steel up to 10 gauge (3.5 mm). You can use it to punch mild steel, aluminum, fiberglass, and plastic. It's quite versatile in operation as it can work with battery - powered, hydraulic, ratchet, or manual drivers. If you use 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 sizes are related to conduit sizes (where the hole size is the outside diameter of US conduit sizes, like a 1/2' conduit size punch making a 7/8' hole), Pg Sizes (European standard pipe sizes), and ISO Sizes (International Standards Organization pipe sizes).
Using the Greenlee 730BB - 1 is easy. First, make sure you have the right punch, die, and draw stud for your project. 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 assemble the punch and die through the pilot holes. Then, place the material you want to punch (it can be mild steel, aluminum, fiberglass, or plastic) in the right position. Operate the driver, and the unit will make a clean hole quickly. Remember, this unit can only punch through mild steel up to 10 gauge (3.5 mm), so don't try to punch thicker materials. After use, clean the punch and die with a dry cloth to keep them in good condition. Store the unit in a dry place to prevent rusting. If you notice any damage to the punch, die, or draw stud, replace them immediately to ensure accurate and safe punching.
