Greenlee 28154 Slug-Splitter SC (Self-Centering) Knockout Punch 1/2 Conduit Size

Using the Greenlee 28154 Slug - Splitter Knockout Punch is quite straightforward. First, select the appropriate power source - you can use a battery, hydraulic, or high - leverage ratchet driver. Place the self - centering punch on the pilot hole, and it will align itself automatically. You don't need to draw crosshairs or line up die alignment marks, which saves you time. When punching, it can handle 10 - gauge (3.5 mm) mild steel and stainless steel with ease. After punching, the unique punch profile will split the slugs, making them easy to remove. For conduit sizes, keep in mind that the hole size is the outside diameter of US conduit sizes, like a 1/2' conduit - size punch creating a 7/8' hole. As for maintenance, regularly check the heavy - duty dies and stainless - steel draw studs for any signs of wear. Since it has good abrasion resistance, it can be used on fiberglass and plastic, but still clean it after use to keep it in top condition. Also, make sure to use the corresponding die (28155) and draw studs as specified. Remember, this punch can only be used with the mentioned power sources, so don't try other drivers.
