Greenlee 50057529 – Frequently Asked Questions

1) I need to cut a 2-1/2 inch hole. Does the Greenlee 50057529 arbor go that big?
No. The 50057529 stops at 2-1/4 inch. Anything above that needs the larger arbor in the Greenlee line, which picks up where this one ends. Below 5/8 inch you are also out of range and want the small-diameter arbor.
2) What does the quick change part of the Greenlee 50057529 arbor actually do for me on the job?
It is a quick change design, which means the saw comes off and the next size goes on without chucking down on a pilot bit or wrenching a threaded hub. On a panel or a run of boxes where you are stepping between 5/8 inch and 2-1/4 inch cuts, that is the difference between a tool change and a stop.
3) Is the Greenlee 50057529 arbor built to drive carbide hole saws or just bi-metal?
Material is listed as carbide cutter shank, so it is intended to drive carbide-tipped cutters, not only bi-metal. That matters if you are going through stainless boxes, enclosure panel, or tile backer where a bi-metal saw dulls fast.
4) Does the Greenlee 50057529 come with a hole saw, or is it the arbor only?
Arbor only. The 50057529 is the mandrel that carries the saw, so you order the cutters separately in whatever diameters your job calls for, anywhere in the 5/8 inch to 2-1/4 inch band.
5) How long is the Greenlee 50057529 arbor, and will it reach in a tight junction box?
Overall the arbor measures 6.6 x 3.3 x 1.6 inches. Only part of that length is shank projecting past the saw, so in a shallow back-box or between studs you should measure your clearance against the 6.6 inch figure before committing to a cut from a fixed angle.
