Greenlee 37157 – Frequently Asked Questions

1) What size hole saws does the Greenlee hex shank arbor work with?
The Greenlee arbor is sized for smaller hole saws, covering 9/16 inch through 1-3/16 inch (14.300 to 30.200 mm). If you're cutting bigger openings for conduit or recessed cans, you need the larger-capacity arbor, not this one.
2) Which hex shank sizes can I order for this Greenlee hole saw arbor?
Four shank sizes: 1/4 inch (37157), 3/8 inch (37154), 7/16 inch (37155), and 1/2 inch (37156). Pick the one that matches your drill or impact chuck before you order, since the shank is the part that determines whether it seats properly.
3) Will a 7/16 inch hex shank arbor fit my drill?
The 7/16 inch hex shank version (11.100 mm) calls for a drill with at least a 1/2 inch chuck capacity. A 3/8 inch chuck will not close on it. If your drill is a 3/8 inch chuck, order the 3/8 or 1/4 inch hex shank version of the same arbor instead.
4) Can I use this Greenlee arbor with carbide grit hole saws, or only bimetal?
Both. The arbor accepts Greenlee bimetal hole saws, recessed light hole saws, and carbide grit hole saws, as long as the saw falls in the 9/16 to 1-3/16 inch range the arbor covers.
5) How do I reach through a deep wall or joist bay with this hole saw arbor?
Greenlee's #901 and #904 bit extensions mate with this arbor for extended reach work, which is how you get through deep stud bays or back-to-back framing. The extension is a separate item, not included.
6) Does this hole saw arbor come with a pilot drill bit?
Yes, a high speed steel pilot drill is part of the arbor. It has a split-point tip, which is the detail that keeps it from walking when you start a hole on sheet metal or a smooth surface.
7) Why choose a hex shank arbor over a round shank one?
A hex shank grips flats in the chuck rather than relying on friction, so it doesn't spin out under the high torque a hole saw generates when the teeth grab. That's the reason electricians running box and conduit holes tend to spec hex over round. The tradeoff is chuck capacity: a 7/16 or 1/2 inch hex needs a 1/2 inch chuck.
8) Is this Greenlee arbor made in the USA?
Yes, the arbor is manufactured in the United States, which matters if you're buying against a domestic-content requirement on a government or institutional job.
9) How is this arbor packaged for stocking on a truck or in a crib?
It ships as a standard pack, single arbor with its pilot drill, no bulk carton or multi-pack. Straightforward to stock one of each hex size on a service van.
