Greenlee 36508 1-7/32 Hole Size Slug-Buster Knockout Punch Unit

Using the Greenlee 36508 Slug - Buster Knockout Punch Unit is quite straightforward. First, choose the right driver for your needs - it can be battery - powered, hydraulic, ratchet, or manual. If you're using a ratchet, hydraulic, or battery driver, you don't need to worry about the draw stud as it's part of the driver kit. Just get the punch and die. This punch unit is great for punching mild steel, aluminum, fiberglass, and plastic. But keep in mind, its capacity is limited to mild steel up to 14 gauge. When it comes to conduit sizes, the hole size is the same as the outside diameter of US conduit sizes. After each use, make sure to clean the punch and die to keep them in good condition. If there are any slugs stuck, the unique punch profile is designed to split them for easy removal. Store the unit in a dry place to prevent rusting and damage.
