Greenlee 50057669 – Frequently Asked Questions

1) What hole sizes come in the Greenlee 50057669 cutter head kit?
Five cutter heads ship in the kit: 7/8, 1-1/8, 1-3/8, 1-3/4 and 2 inch. Those are the knockout-style hole diameters, and they cover the run of sizes most often punched or cut in panel walls and enclosures on an electrical job.
2) Do I need to buy an arbor separately for the Greenlee 50057669 hole cutter set?
No. The arbor is packed in the kit along with the five cutter heads, a hex key, a set screw, an ejector spring, and a carrying case. You supply the drill; everything needed to mount and drive the heads is in the box.
3) If I lose the hex key or strip the set screw on this Greenlee cutter head kit, can I get parts?
The wear parts are catalogued individually: a 3 mm hex key (3581), a set screw (54274), and a 1/2 inch ejector spring (55225). The ejector spring and set screw are the two that go first on a kit that gets daily use, so they are worth keeping on the truck.
4) Is a cutter head kit the right choice, or should I be using a knockout punch set?
Cutter heads like the 50057669 set mount on an arbor and are driven by a drill, so they cut the hole outright, which is the faster route when you can get a drill square to the work and the material is thin gauge. A hydraulic or ratchet knockout punch pulls the slug through instead and needs a pilot hole first, but it works better in tight enclosures where a drill will not fit and in heavier stock. Many crews carry both and reach for the cutter heads on open panel work.
5) How big is the Greenlee 50057669 cutter head case and will it fit in a tool bag?
The case measures 8.95 x 7.7 x 2.2 inches and the packaged weight is 1.63 pounds, so it drops flat into a standard tool bag or the lid tray of a job box without taking a whole compartment.
6) Does the Greenlee 50057669 kit come with an ejector spring installed for slug removal?
An ejector spring, sized 1/2 inch, ships with the kit and is also listed as a replacement item. It is what pushes the cut slug clear of the head so you are not digging it out between holes.
7) What is the manufacturer part number to order this Greenlee cutter head set by?
Order it as Greenlee 50057669. That single number covers the complete kit, five heads plus arbor, hex key and case, so there is no separate configuration to specify.
