Greenlee 28166 – Frequently Asked Questions

1) What size hole does the Greenlee 28166 die actually cut?
The 28166 is a 2 inch conduit trade size die, and the finished hole it cuts is 2-3/8 inches (61.5 mm). That's the correct opening for a 2 inch IPS conduit hub or connector, so don't go looking for a 2 inch hole, trade size and hole size are not the same number on knockout dies.
2) Will the Greenlee 28166 punch through a stainless steel enclosure?
Yes, up through 10 gauge stainless steel. That covers most stainless panel and enclosure work as well as mild steel of the same or lighter gauge. Above 10 gauge stainless you're outside what this die is rated to cut.
3) Does the 28166 work with a battery knockout tool or only a hydraulic pump?
Both. The Slug Splitter SC 2 inch round die is built to run on battery-powered, hydraulic, and ram-style knockout drivers, so one die covers whichever setup is on the truck that day.
4) Is the Greenlee 28166 a complete punch set or just the die?
It is the die only, a genuine Greenlee replacement within the Slug Splitter SC system. If your existing SC punch, draw stud, and driver are already in service, this drops in as the 2 inch round replacement. Buying it to start from scratch means you still need the matching punch and draw stud plus a driver.
5) What does the SC in Slug Splitter SC mean, and why does it matter on panel work?
SC is self-centering. The die geometry keeps the punch aligned to the pilot hole as pressure builds, so the knockout comes out round and on-center instead of drifting. On a panelboard or a row of enclosure penetrations that's the difference between a connector that seats flush and one that fights you.
6) What is the Greenlee part number for the 2 inch Slug Splitter SC round die, and where is it made?
Order it as Greenlee 28166. It's made in the United States, which matters if you're buying against a domestic-content requirement on a government or institutional job.
7) Can I use this die on a round enclosure or curved surface?
Yes. The 28166 produces a round knockout and is specified for round enclosures, which is the typical case for conduit entry on panelboards and enclosure bodies. The hole profile is round, suited to standard conduit hubs and connectors rather than square or D-shape device cutouts.
