Greenlee 52084927 11-Ton Hydraulic Knockout Kit with Hand Pump, 1/2" - 4"

The Greenlee 52084927 is an 11-Ton hydraulic knockout kit built for electricians and contractors who need to punch clean, accurate holes in electrical enclosures, panels, and boxes from 1/2" up to 4" conduit size. This kit pairs a 746A hydraulic ram with a 767 hand pump, delivering the muscle needed to punch up to 10 ga mild steel or 12 ga stainless steel without the need for compressed air or electric power. Manufactured in the USA from US and global components, the 52084927 combines Slug-Buster® punches, Standard Round punches, and a full set of dies into one field-ready system housed in a durable KCC-7674 carrying case. Whether you're punching small conduit entries or large panel knockouts, this kit gives you a single, self-contained solution for demanding jobsite work.

  • Slug-Buster® Punches (1/2" - 2"): Slug-Buster technology eliminates loose slugs, reducing debris and speeding up the punching process on smaller conduit sizes.
  • Standard Round Punches (2-1/2" - 4"): Handles larger conduit sizes with the same reliable hydraulic pressure as the smaller Slug-Buster punches.
  • Full Die Set (1/2" - 4"): Matching dies for every punch size in the kit ensure a proper fit and clean hole for each knockout.
  • Hydraulic Draw Studs: Includes 7/16", 3/4", and 1-1/8" draw studs to accommodate the full range of punch and die combinations in the kit.
  • Material Capacity: Rated to punch up to 10 ga mild steel or 12 ga stainless steel, suitable for demanding panel and enclosure work.

Greenlee 52084927 – Frequently Asked Questions

1) What conduit sizes will the Greenlee 52084927 knockout kit punch?
The 52084927 kit covers 1/2 inch through 4 inch conduit size knockouts, which works out to finished holes of 0.89 inch to 4.54 inch (22.5 mm to 115.4 mm). Slug-Buster punches handle the 1/2 inch to 2 inch range, and standard round punches cover 2-1/2 inch through 4 inch. Dies are included across the full 1/2 inch to 4 inch span.
2) How thick a panel can this 11-ton hydraulic knockout set punch through?
Rated to punch up to 10 gauge mild steel or 12 gauge stainless steel. That covers most enclosure walls, panelboard cans, wireways and junction box sides. For material types, it will punch mild steel, stainless, aluminum, brass, copper, fiberglass and plastics.
3) Does the Greenlee 52084927 come with a pump, or do I need to buy one separately?
The pump is in the kit. It ships with the 746A ram and the 767 hand pump, so no separate power source or battery tool is needed. Hand pump means no electricity on site, which is why crews use this set for rough-in work in unenergized buildings.
4) What is the difference between the Slug-Buster punches and the standard round punches in this set?
Both cut the same conduit trade sizes, they just work differently. Slug-Buster punches, supplied here for 1/2 inch through 2 inch, break the slug into pieces that drop free rather than wedging in the die. The 2-1/2 inch to 4 inch punches in this kit are standard round, which leave a full slug you pop out of the die by hand.
5) Can I use this on a stainless steel enclosure, or only painted mild steel?
Stainless is within the rating, up to 12 gauge. In mild steel the limit is 10 gauge. Aluminum, brass, copper, fiberglass and plastic panels are also listed applications, so the same set handles NEMA 4X stainless boxes and fiberglass pull boxes.
6) Will a 4 inch punch from this kit make the right hole for 4 inch rigid conduit?
Yes. The punches and dies are sized by conduit trade size, and the 4 inch punch produces a 4.54 inch hole, which is the clearance a 4 inch conduit hub or locknut needs. The full range runs 0.89 inch at 1/2 inch conduit up to that 4.54 inch hole.
7) Where is the Greenlee 52084927 driver made?
Country of origin is the US, and the driver is manufactured in the USA from US and global components. For agencies and institutions with domestic sourcing language on the PO, that is the statement Greenlee publishes for this kit.
