Greenlee 31119 Slug Splitter® SC Round Knockout Punch

The Greenlee Slug Splitter® SC Round Knockout Punch series, available in Model 31119 and Model 36490, is engineered to produce clean, precisely sized round openings in electrical enclosures, panelboards, and equipment housings. These standard round punches are part of the Greenlee Slug Splitter® SC lineup and are built for use with battery-powered, hydraulic, and ram-style knockout drivers, giving installers flexibility across whatever power source is on the jobsite. Both models in this family are rated for capacity through 10 gauge stainless steel and are manufactured in the United States, giving electricians and panel fabricators a durable, accurately sized punch for creating repeatable round knockouts in enclosure and panel material, including heavier-gauge stainless steel in addition to standard mild steel.

Greenlee 31119 – Frequently Asked Questions

1) What hole sizes does the Greenlee 31119 Slug Splitter SC round knockout punch come in?
Two sizes are offered in this round Slug Splitter SC group: model 31119 cuts a .73 inch round hole, and model 36490 cuts 1-7/32 inch. Order by the model number that matches the hole you need, since each model is a single fixed diameter.
2) Will a Greenlee Slug Splitter SC punch go through a stainless steel enclosure, or only mild steel?
Stainless is covered. The Slug Splitter SC round punch is rated for capacity through 10 gauge stainless steel, which also covers standard mild steel enclosure and panelboard material at that gauge or lighter. Heavier than 10 gauge stainless is outside its rating.
3) Can I use this knockout punch with my battery-powered driver, or does it need a hydraulic pump?
Either works. The Slug Splitter SC round punch is built for battery-powered, hydraulic, and ram-style knockout drivers, so you can run it off whatever driver is on the truck that day rather than buying a punch per tool.
4) Are Greenlee Slug Splitter SC knockout punches made in the USA for a Buy American job?
Country of origin on the Slug Splitter SC round punch is the United States. That is the manufacturing origin as published by Greenlee; for federal or state procurement you would still document it against your own contract clause.
5) What is the difference between a slug splitter punch and a standard round knockout punch?
A standard round punch shears out one solid slug that drops into the enclosure and has to be fished out. The Slug Splitter SC design splits the slug as it cuts, so the pieces release instead of staying wedged in the draw stud area, which matters when you are punching an energized or populated panel. The hole produced is the same standard round shape either way, round profile for conduit and fitting entry points.
6) Does a Greenlee Slug Splitter SC punch come with the draw stud and driver, or just the punch and die?
These are sold as knockout punch units, not as a complete kit with a driver. The punch is intended to be mated to a battery, hydraulic, or ram driver you already have, so plan on supplying the driver and the draw stud that suits it.
7) Is the Greenlee 31119 punch itself stainless steel, or is that just what it cuts?
Both things are true but they are separate facts. The punch is catalogued with stainless steel as its product material, and its rated cutting capacity runs through 10 gauge stainless steel panel.
