Greenlee K2P-3/4 – Frequently Asked Questions
1) How thick a panel can the Greenlee 3/4 inch Slug-Buster punch go through?
Rated to punch 10 gauge mild steel or 12 gauge stainless steel. Mild steel is what it is optimized for, stainless capability is limited, so on stainless enclosures stay at 12 gauge or thinner.
2) Do I need anything else to use a Greenlee Slug-Buster knockout punch?
The punch alone does not make the hole. You need a matching die and draw stud plus a driver, and the K2P-3/4 works with Greenlee battery-hydraulic knockout drivers, manual-hydraulic knockout drivers, or a ratchet wrench. You also drill a pilot hole for the draw stud first.
3) Will this punch work on stainless steel enclosures or only painted steel panels?
Material range covers mild steel, stainless steel, brass, copper, aluminum, fiberglass and plastics. Mild steel is the design target. On stainless, capability is limited and capped at 12 gauge, so for repeated heavy stainless work a punch rated for stainless duty is the better call.
4) What does Slug-Buster mean and why does it matter on a service upgrade?
The Slug-Buster profile splits the slug as it cuts instead of leaving a full disc trapped in the die. The pieces drop free, so you are not prying a stuck slug out of a live panel or fishing it off the bottom of an enclosure. On a panel with a dozen knockouts that is the difference in cleanup time.
5) Is the Greenlee K2P-3/4 punch round or does it cut a square hole?
Round. It cuts the standard round conduit knockout at 1.12 inches. For square or D-shaped openings you need a dedicated square punch, not this one.
6) Is the Greenlee 3/4 inch knockout punch made in the USA?
Country of origin is the United States. Useful if you are bidding work with domestic sourcing requirements on tooling.
7) What are the dimensions and weight of the K2P-3/4 punch?
It measures 0.81 by 2.9 inches and weighs 0.15 lb, so it drops into a pouch or driver case without adding meaningful weight to the kit.
