Greenlee 60040 – Frequently Asked Questions

1) Will the Greenlee 60040 rectangular punch work with the hydraulic driver I already own?
The 60040 rectangular punch unit is built to run on any Greenlee hand or hydraulic driver, so it drops into an existing Greenlee setup without a different ram or adapter. Each unit comes with its own draw stud and nuts, which is the part that ties the punch to the driver.
2) What rectangular sizes does the Greenlee 60040 punch series come in, and which part number is which?
Four rectangular sizes, each its own Greenlee part number: .861 x 1.01 inch is 60037G, .866 x 1.18 inch is 60040, .866 x 1.65 inch is 60043, and .990 x 1.14 inch is 60047G. Order by the finished opening you need in the panel, not by the conduit trade size.
3) How thick a panel can a Greenlee 60040 rectangular knockout punch cut?
Up to 14 gauge mild steel. That covers most electrical panels, panelboard sides and sheet steel enclosures. Heavier plate or stainless is outside what this punch is rated to cut, so for thicker material you want a punch rated for it rather than forcing this one.
4) Do I need to buy a die and draw stud separately for the Greenlee 60040?
No. Each size ships as a complete assembly: punch, die, draw stud and nuts. The only thing you supply is the driver, hand or hydraulic.
5) What is the size range covered by the Greenlee 60040 rectangular punch line in millimetres?
The range runs from .861 x 1.01 inch (21.9 x 25.7 mm) up to .990 x 1.14 inch (25.1 x 29.0 mm), with .866 x 1.18 inch (22.0 x 30.0 mm) and the longer .866 x 1.65 inch (22.0 x 41.9 mm) in between. If you are matching a metric enclosure cutout or a rectangular connector body, work from those mm figures.
6) Is a rectangular knockout punch the right choice, or should I use a round one?
Use the rectangular unit when the opening itself has to be rectangular, for example a rectangular connector, a device cutout or a slot in an enclosure face. Round conduit knockouts for EMT or rigid are cut with a round punch sized to the conduit trade size instead. The 60040 series is rectangular only and will not produce a round hole.
7) Is the Greenlee 60040 punch made in the USA?
Yes, the 60040 rectangular punch units are manufactured in the United States. The punch and die are steel. That matters on public and institutional jobs where domestic sourcing is part of the spec.
8) Can I use the 60043 punch to get a long slot instead of stacking two cuts?
The 60043 gives a .866 x 1.65 inch opening, the longest of the four rectangular sizes, so it cuts a single clean slot in one stroke rather than overlapping two smaller punches. Overlapped cuts leave a ragged waist; one punch does not.
