Greenlee K2P-3/4-B – Frequently Asked Questions

1) What hole size does the Greenlee K2P-3/4-B knockout punch actually cut?
The K2P-3/4-B cuts a round hole of 1.12 inches (28.3 mm), which is the knockout size a 3/4 inch conduit fitting needs. The "3/4" in the part number is the trade conduit size, not the hole diameter, so don't order it expecting a 3/4 inch opening.
2) What material thickness can the Greenlee 3/4 inch Slug-Buster punch handle?
Rated for 10 gauge mild steel or 12 gauge stainless steel. Capacity is optimized for mild steel, with limited stainless capability, so if you are punching a stainless enclosure keep it at 12 gauge or thinner.
3) What else do I need to buy to use the Greenlee K2P-3/4-B punch?
The punch is one piece of a three-piece set. You also need the matching Greenlee die and a draw stud, plus a way to pull it: a Greenlee battery-hydraulic knockout driver, a manual-hydraulic driver, or a ratchet wrench. Ordering the punch alone will not make a hole.
4) Can I use this knockout punch on aluminum or plastic enclosures, not just steel panels?
Yes. The Slug-Buster round punch is listed for mild steel, stainless steel, brass, copper, aluminum, fiberglass and plastics, which covers field modification of fiberglass and PVC enclosures as well as metal panelboards.
5) Is this a replacement punch for a Greenlee knockout set I already own?
Yes, that is the normal use. The K2P-3/4-B is sold as the individual 3/4 inch conduit round punch, so you can replace a dulled or lost punch in an existing Greenlee Slug-Buster kit without rebuying the whole set. It still pairs with your existing 3/4 inch die and draw stud.
6) Will this punch give me a round hole or a square one for a conduit fitting?
Round. The configuration is a round knockout sized for conduit fittings. If you need a rectangular or square opening for a device, a pushbutton, or a D-sub cutout, this is the wrong punch shape.
7) What does Slug-Buster mean, and does it matter on a panel install?
The Slug-Buster profile is cut so the slug splits as the punch passes through instead of coming out as a solid disc. On an energized or wired panel that matters: a split slug falls free and can be picked out rather than jamming in the die or dropping whole into the enclosure.
8) Is the Greenlee K2P-3/4-B made in the USA for buy-American jobs?
Country of origin is the United States, which is what institutional and government procurement typically needs on the submittal.
