Greenlee 28155 Slug-Splitter Self-Centering Knockout Die – 7/8-Inch, Die Only

This Greenlee Slug-Splitter knockout die is the 7/8-inch size, and it's just the die – you'll need the matching punch and draw stud to use it. It's part of Greenlee's heavy-duty SC series designed to punch through up to 10-gauge (3.5mm) stainless steel and mild steel. The self-centering feature means it aligns itself on the pilot hole, so you don't have to fuss with crosshairs or marks. The unique design splits the slug for easier removal. Works with Greenlee punch #28154 and draw studs #29451 or #30227. Can be used with ratchet drivers (like #1904) or hydraulic drivers. Essential for electricians, metalworkers, or HVAC techs who need clean, precise holes in panels, boxes, or enclosures. A professional-grade tool that saves time and effort. Just make sure you have the complete set before starting your job.
