Greenlee 113AV – Frequently Asked Questions

1) What size round knockout punches does the Greenlee 1791AV family cover, and what are the part numbers?
Three round sizes, each with its own Greenlee part number: 3/4 inch is 113AV, 1-7/8 inch is 1791AV, and 2-5/8 inch is 1795AV. Order by the hole size you need to cut, not by the conduit trade size printed on the fitting, and match the number exactly so the punch threads onto your existing draw stud setup.
2) How thick a steel panel will a Greenlee 1791AV round punch cut?
Mild steel up to 10 gauge is the rated capacity. It will also go through aluminum, fiberglass, and plastic enclosure panels. For stainless steel or anything heavier than 10 gauge mild steel, this punch is not the right tool.
3) Can I use these replacement punches with a battery-powered knockout driver, or only a manual ratchet?
Both. The 1791AV round punch units work with battery-powered, hydraulic, ratchet, or manual driver systems, so the same punch moves between a hand ratchet setup and a cordless punch driver.
4) Which Greenlee round punch do I need for 2 inch conduit?
Conduit trade size and hole size are not the same number. A 2 inch conduit fitting needs a 2-5/8 inch hole, which is the 1795AV. The 1791AV cuts 1-7/8 inch, the hole for 1-1/2 inch conduit, and the 113AV cuts 3/4 inch, which suits 1/2 inch conduit. Confirm the hole diameter your fitting calls for before ordering.
5) My 1-7/8 inch punch is worn out. Do I have to buy a whole new knockout set?
No. The 1791AV is sold as an individual round replacement punch unit, so you replace just the worn or chipped punch and keep your existing dies and draw studs. That is the point of the AV series: renew the one size that is dull instead of buying a complete set.
6) Does the replacement punch come with a die and draw stud, or just the punch?
The 1791AV series is a punch unit, meant to restore the cutting element in tooling you already own. If your die has mushroomed or your draw stud is stretched, those are separate items and you will need to source them alongside the punch.
7) Will these punches cut a clean hole in a fiberglass or PVC enclosure without cracking it?
Fiberglass and plastic enclosure material is within the rated capacity of the 1791AV round punches, along with aluminum. A shear punch like this produces a round hole sized for standard conduit and fitting entry, which is generally cleaner on composite panels than a hole saw.
8) Are Greenlee 1791AV punches made in the USA?
Yes, the 1791AV round replacement punch units are of United States origin, which matters if you are buying against a domestic-preference or Buy American tool requirement on an institutional or government job.
