Greenlee 28158 Slug-Splitter SC (Self-Centering) Knockout Punch 1 Conduit Size

Using the Greenlee 28158 Slug - Splitter Knockout Punch is straightforward. First, select the right draw stud according to your driver type, like the 31872 for certain hydraulic drivers or 12099 for the ratchet driver. Then, place the self - centering punch on the pilot hole, and it will align itself automatically, so you don't need to draw crosshairs or worry about die alignment marks. Connect it to a battery, hydraulic, or high - leverage ratchet driver to start punching. When punching, remember it's designed for 10 - gauge (3.5 mm) mild steel and stainless steel, and it has great abrasion resistance for fiberglass and plastic. The unique slug - splitting design will make removing slugs easier. For maintenance, keep the heavy - duty dies and stainless - steel draw studs clean. After each use, wipe them down to prevent rust and ensure a longer lifespan. And since it's a patented - pending product, use it as intended to get the best results.
