Greenlee 7906SB – Frequently Asked Questions

1) What conduit sizes will the Greenlee 7906SB knockout kit punch?
The 7906SB Quick Draw 90 kit covers 1/2 inch through 2 inch conduit size knockouts, which works out to finished hole diameters of 0.89 inch to 2.42 inch (22.5 mm to 61.5 mm). Those are the sizes that cover most panel and enclosure work. Anything above 2 inch conduit needs a larger driver and punch set.
2) How thick a panel can an 8-ton knockout driver punch through?
The 8-ton Quick Draw 90 driver is rated to punch up to 10 gauge mild steel or 12 gauge stainless steel. Stainless is harder, so the rating drops a couple of gauges. It also handles aluminum, brass, copper, fiberglass, and plastic enclosures.
3) What actually comes in the Greenlee 7906SB kit?
You get the Quick Draw 90 hydraulic knockout driver, the 1/2 inch to 2 inch Slug-Buster punches and matching dies, a 3/4 inch short hydraulic draw stud, a 7/16 inch short hydraulic draw stud, and the KCC-QD2 carrying case. No separate pump or hose is needed, the driver is self contained for one-person use.
4) Will the Greenlee 7906SB work with punches I already own?
The driver accepts all Greenlee knockouts up to 2 inch, so existing Greenlee punches and dies in that range mount on the same draw studs. The kit ships with both a 3/4 inch and a 7/16 inch short hydraulic draw stud, which are the two stud sizes the smaller and larger punches in that range use.
5) Do I still have to pry the slug out after punching?
No. The Slug-Buster punch profile splits the slug as it cuts, so it drops free instead of wedging in the die. On a panel with a dozen knockouts that is the difference between a few minutes and a screwdriver fight.
6) Can I punch stainless steel enclosures with the 7906SB, or will it damage the dies?
Stainless is within the rating, up to 12 gauge. The die design on the Quick Draw 90 line was built for the broad material range, and the listed materials include both mild steel and stainless steel. Keep in mind stainless caps out two gauges thinner than mild steel at 8 tons, so a heavier stainless cabinet is outside what this driver will cut.
7) What is the Greenlee part number for the 8-ton Quick Draw 90 SlugBuster kit, and where is it made?
The manufacturer part number is 7906SB, and it is made in the United States. Note that Greenlee flags this kit under CA Prop 65 for cancer.
8) Are the holes this kit cuts round, and how do I keep them centred on a layout line?
All punches in the set cut round holes. The punches carry laser alignment markings for centring on your layout, plus laser part identification so you can pick the right size out of the case quickly. The draw studs use a dog point tip to stop cross-threading when you thread up in an awkward panel.
