Greenlee 60001 – Frequently Asked Questions

1) Will this Greenlee square punch work with the hydraulic driver I already own?
The square punch unit is built to run with any Greenlee hand or hydraulic driver, so whichever Greenlee ram, hand knockout set, or hydraulic pump you already carry on the truck will drive it. No driver is included with the punch unit itself.
2) I need a square cutout for a panel-mount switch. Is a round knockout punch going to work?
No. A round punch leaves a circular hole that will not seat a square-bodied device, and filing a round hole square distorts the metal. The 60001 family is a purpose-built square punch, giving straight edges and square corners in sizes 1/2 inch, 7/8 inch, and 1-13/16 inch for switches, indicators, and other square panel-mounted components.
3) Is a knockout punch better than a hole saw for cutting openings in an electrical enclosure?
For sheet metal enclosures, a punch is the cleaner choice. Punching shears the opening in one stroke at the specified dimension, which avoids the burrs and metal distortion you get from hole saws or manual cutting, and it leaves a repeatable opening so panel-mounted devices fit up without rework. A hole saw also can't produce a square profile at all, which is the whole point of this unit.
4) Is the Greenlee square knockout punch made in the USA for a Buy American spec job?
Country of origin is the United States, manufactured to Greenlee's standards for professional electrical tooling. That is the sourcing fact institutional and government buyers usually need on the submittal; confirm the specific domestic-content clause on your contract applies to tooling as well as installed materials.
5) Does the Greenlee 60001 punch unit come with the draw stud and die, or is it punch only?
The 60001 and its siblings are sold as punch units, meaning the matched punch and die assembly sized to the opening. The driver, whether a hand ratchet wrench or a hydraulic ram and pump, is separate and must already be on hand or ordered alongside.
6) Which square punch size should a panel builder stock first?
The 1/2 inch and 7/8 inch squares cover most standard panel and enclosure openings for switches and pilot devices, so those two carry the bulk of day-to-day control panel work. The 1-13/16 inch (46.0 mm) square is the one to add when you are cutting larger device or display openings in switchgear and control panel modifications.
