Greenlee 28160 Slug-Splitter SC (Self-Centering) Knockout Punch 1-1/4 Conduit Size

Greenlee 28160 Key Details: The hole size of this punch corresponds to the outside diameter of US conduit sizes. For example, a 1/2' conduit size punch creates a 7/8' hole. The corresponding die is 28161, and there are various draw studs for different drivers. Features: This heavy - duty slug - splitter punch can easily punch through 10 gauge (3.5 mm) stainless and mild steel. Its self - centering design aligns on the pilot hole, eliminating the need for crosshairs or die alignment marks. The unique punch profile splits slugs for easy removal. It comes with heavy - duty dies and stainless steel draw studs for long - lasting use. It also has great abrasion resistance for punching fiberglass and plastic. It can be operated with battery, hydraulic, or high - leverage ratchet drivers. It's a patent - pending product.

How to use: First, select the appropriate draw stud according to your driver (like 31872 for certain hydraulic drivers). Place the self - centering punch on the pilot hole. Then use your battery, hydraulic, or high - leverage ratchet driver to operate the punch. When punching, make sure the material (like 10 gauge stainless or mild steel) is properly positioned. Note: Only use it with the specified drivers. Avoid using it on materials that are too thick or hard other than what it's designed for. Maintenance: After use, clean the punch, die, and draw studs to remove any debris. You can apply a light coat of oil to prevent rust and ensure smooth operation. Store it in a dry place to extend its lifespan.
