Greenlee 735BB – Frequently Asked Questions

1) Can the 735BB punch set cut holes in stainless steel?
No. The Greenlee 735BB round knockout set is rated for mild steel, aluminum, fiberglass and plastic. Stainless steel enclosures need a punch specifically rated for stainless, so don't put these dies into a stainless panel.
2) Does the Greenlee 735BB knockout set need a hydraulic driver or is it hand operated?
It's a manual set. The 735BB drives with a wrench on the draw stud, no hydraulic ram or battery tool required. That makes it a good kit to keep in the van for occasional panel and junction box work; if you're punching all day or working larger sizes, a hydraulic driver setup is the faster choice.
3) What comes in the Greenlee 735BB kit?
The 735BB ships as a complete kit: the round punches, the matching dies, draw studs and a carrying case for storage and transport. Punches, dies and case are made in the United States. You supply the drill for the pilot hole and a wrench to turn the draw stud.
4) Are these round punches or do they cut square/rectangular openings?
Round only. The 735BB set punches standard round knockouts from 1/2 inch to 1-1/4 inch. Square or rectangular openings for device boxes, meters or panel cutouts need a separate square punch set.
5) Is the Greenlee 735BB suitable for punching fiberglass enclosures?
Yes. Along with mild steel and aluminum, the set is rated for fiberglass and plastic, so it works for non-metallic enclosures as well as standard steel panels and junction boxes. Greenlee lists the die design as optimized for that range of materials.
6) How do you get the slug out after punching with the Greenlee 735BB?
The punches use Greenlee's Slug-Buster profile, which splits the slug as it cuts so it drops out instead of wedging in the die. Less picking at the scrap on a ladder, which is the real time saver on a panel full of knockouts.
7) Will the draw stud strip or cross-thread in the punch?
The draw studs on the 735BB use a dog point tip that starts the thread straight and helps prevent cross-threading, and the punches have knurled edges so you can grip and start them by hand without slipping. Cross-threaded studs are the usual way these kits die, so that detail matters if the kit is shared across a crew.
