Greenlee 7704SB – Frequently Asked Questions

1) What size knockouts will the Greenlee 7704SB Quick Draw Flex punch?
The 7704SB kit covers 1/2 inch through 2 inch conduit size knockouts, which works out to finished holes of 0.89 inch to 2.42 inch (22.5 mm to 61.5 mm). The KCC-QDF2 case is laid out for that range, and the driver itself works with all Greenlee knockouts up to 2 inch. Anything above 2 inch conduit needs a larger-capacity driver.
2) How thick a panel can the 7704SB punch through?
Rated to punch up to 10 gauge mild steel, or 12 gauge in stainless. That covers most electrical enclosures, panel sides, and junction boxes. It also punches aluminum, brass, copper, fiberglass, and plastics. If you are working stainless heavier than 12 gauge, this 8-ton driver is not the tool.
3) What comes in the Greenlee 7704SB kit, and what else do I need to buy?
The kit ships with the Quick Draw Flex driver, a 7/16 inch short hydraulic draw stud, a 3/4 inch short hydraulic draw stud, and the KCC-QDF2 carrying case. The punches and dies themselves are not part of the kit, so you order the Greenlee knockout sets or individual punch and die pairs for the hole sizes you need, up to 2 inch.
4) Will the 7704SB work with Greenlee punches I already own?
Yes. The Quick Draw Flex driver is compatible with all Greenlee knockouts up to 2 inch, and the two included draw studs are the 7/16 inch and 3/4 inch sizes Greenlee punches use. Existing Greenlee sets in that range carry straight over.
5) Do I need a separate hydraulic pump or foot pump for the 7704SB?
No. The Quick Draw Flex is a self-contained 8-ton hydraulic knockout driver built for one-person operation, so there is no remote pump or hose to set up. You thread the draw stud, seat the punch and die, and run it at the tool.
6) Can I use this driver inside a crowded panel where there is no room to swing a tool?
That is what the Flex Head is for. The head articulates so the driver can be worked in tight, low-clearance spots, which is the usual problem when punching the side of a loaded enclosure or a panel in a cramped wall cavity.
7) Why do my draw studs keep cross-threading, and does the Greenlee 7704SB fix that?
The draw studs in this kit use a dog point tip, a reduced lead on the end of the thread that starts the stud straight instead of letting it bite at an angle. They also have hex key access so a stud can be backed out of the tool without a fight if it does bind.
8) Is the Greenlee 7704SB made in the USA for a buy-American job spec?
Country of origin is the United States. The driver is manufactured in the USA from US and global components, and the draw studs and carrying case are also made in the USA. Note that mixed-component language matters on some federal specs, so read the clause on your contract against that wording.
9) Does the Greenlee 7704SB carry a California Prop 65 warning?
Yes, a cancer warning applies, listing diisononyl phthalate (DINP). No reproductive harm warning is attached. Facilities and institutional buyers who log Prop 65 notices on incoming tools should record it on receipt.
