Greenlee 50056956 – Frequently Asked Questions

1) Do I need an arbor and pilot drill to use the Greenlee quick change stainless steel hole cutter?
Yes, both are separate purchases. The cutter mounts on the Greenlee 645-011 arbor, which has a 3/8 inch shank, and the pilot drill is the 645-001 replacement, sized 1/4 inch x 2-1/2 inch (6 mm x 64 mm). Budget for the arbor and pilot on your first order or the cutter head alone won't cut anything.
2) How thick a stainless panel can these Greenlee carbide hole cutters go through?
Maximum cutting depth is 8 gauge material. That covers enclosure walls, panel doors, junction boxes and sheet stainless. For anything heavier than 8 ga you need a different tool, such as a knockout punch set.
3) What sizes do the Greenlee quick change stainless hole cutters come in?
Three diameters: 7/8 inch (MPN 50056956), 1-1/8 inch (50056972), and 1-3/8 inch (50057006). The 7/8 and 1-3/8 sizes line up with 1/2 inch and 1 inch conduit knockouts respectively, so electricians usually buy them as a pair.
4) Will a standard bi-metal hole saw work on stainless, or do I need the carbide cutter?
For stainless, go carbide. These Greenlee cutters use tungsten carbide teeth, which hold an edge in work-hardening stainless where bi-metal teeth dull or glaze over in a hole or two. Run slow speed and steady pressure and the carbide teeth last considerably longer.
5) Will these hole cutters leave a clean enough hole for a cord grip or conduit fitting?
They cut round, burr-free holes, which is what you want when a liquidtight connector or cord grip has to seat and seal against the panel face. No filing or deburring step before the fitting goes in.
6) Can I chuck these Greenlee cutters in a cordless drill?
Yes, through the 645-011 arbor. The arbor has a 3/8 inch shank, which fits a standard 3/8 inch or 1/2 inch drill chuck. The cutter head itself has no shank, it is a quick change head that mounts to that arbor.
7) Do I have to knock the slug out of the cutter by hand after every hole?
No. A slug ejector spring pushes the plug out as you retract, so you're not prying it out with a screwdriver between holes. That matters when you're cutting a row of holes in a panel side and working overhead.
8) Can I replace just the pilot drill when it breaks instead of buying a new cutter?
Yes. The pilot is a separate replaceable item, Greenlee 645-001, at 1/4 inch x 2-1/2 inch (6 mm x 64 mm). Pilots take the abuse first, so MRO shops standardizing on these cutters usually keep a few spare pilots on the shelf.
