Greenlee 7307 1/2 - 2 Conduit Size Slug-Splitter SC Knockout Punch Kit

Using the Greenlee 7307 Knockout Punch Kit is easy. First, choose the right punch for the conduit size you're working with. Place the self - centering punch on the pilot hole and it will align itself automatically, so you don't need to do any complicated markings. Then, use it with your compatible driver, like the Quick Draw series, battery - powered drivers, or the 7646 and 7625 ram - type drivers. When using, make sure the material you're punching is up to 10 gauge (3.5 mm) stainless steel. For maintenance, keep the punches clean after each use. Wipe off any debris or metal shavings. You can also apply a light coat of oil to prevent rusting. Store the kit in a dry place to ensure its long - term performance.
