Greenlee 730BB-11/16 11/16 Hole Size Standard Round Knockout Punch Unit

Using the Greenlee 730BB-11/16 is quite straightforward. First, make sure to assemble the punch, die, and draw stud properly through the pilot holes. When you're ready to punch, choose the right driver - it can be battery - powered, hydraulic, ratchet, or manual. If you're using a battery - powered, hydraulic, or ratchet driver, just get the punch and die as the draw stud comes with the driver kit. This unit is great for materials like mild steel, aluminum, fiberglass, and plastic, but remember its capacity is up to 10 - gauge mild steel (3.5 mm). As for maintenance, after each use, clean the punch and die to remove any debris. Store it in a dry place to prevent rust. When handling, be careful not to drop it as it might damage the precision parts.
