Greenlee 7310SB – Frequently Asked Questions

1) What conduit sizes will the Greenlee 7310SB knockout kit punch?
The 7310SB covers 1/2 inch through 4 inch conduit size knockouts, which works out to finished hole diameters of 0.89 inch up to 4.54 inch (22.5 mm to 115.4 mm). All holes are round. That range covers standard panel and enclosure knockouts from a single half inch connector up to a 4 inch service conduit, so one case handles most electrical work without reaching for a second set.
2) Can this hydraulic punch kit cut through a stainless steel enclosure?
Yes, up to 12 gauge stainless. The 11-ton Greenlee kit is rated to punch mild steel up to 10 gauge and stainless up to 12 gauge, and it also handles aluminum, brass, copper, fiberglass and plastics. Heavier than 10 ga mild or 12 ga stainless is outside what this system is rated for.
3) What comes in the Greenlee 7310SB kit, and do I need to buy a pump separately?
No separate pump needed. The kit ships with the 746A ram and the 767 hand pump, plus the Slug-Buster punch and die sets covering 1/2 inch to 4 inch, draw studs, and the KCC-7674 carrying case. It is a complete manual hydraulic system out of the box, no battery tool or electric pump required.
4) Will these Slug-Buster punches work with my Greenlee battery punch driver?
They will. The punches and dies use the same draw studs as Greenlee Intelli-PUNCH, LS50L2 and the 746A ram, so the cutting components from this kit transfer to those drivers. Draw studs included run 7/16 inch, 3/4 inch and 1-1/8 inch hydraulic sizes.
5) Hand pump or battery hydraulic punch, which should I buy for panel work?
The 7310SB is the manual route: a 767 hand pump driving the 746A ram. It has nothing to charge and nothing to fail on a jobsite, which suits occasional panel and enclosure work or a service truck that sits for weeks between punches. A battery driver such as Greenlee Intelli-PUNCH is faster on repetitive production punching. Because the punches and dies share draw studs with Intelli-PUNCH and LS50L2, buying this kit now does not strand you if you add a battery driver later.
6) Do I still have to drill a pilot hole before using this punch?
Yes. A hydraulic knockout punch works by drawing the punch through a pilot hole with the draw stud, so you drill for the stud first, thread the stud through, seat the die on the back side and pump. The draw studs on this kit use a dog point tip that helps prevent cross-threading, and a hex key socket so you can back a stud out of the tool if it sticks. Alignment marks on the punches help you line the hole up before you put pressure on it.
7) Is the Greenlee 7310SB made in the USA?
Country of origin on the 7310SB is the United States. Specifically the punches, dies, draw studs and case are US-manufactured, with the driver built from US and global components. The kit is also REACH compliant, which matters if you are supplying a facility with a documented chemical compliance requirement.
