Greenlee 38524 – Frequently Asked Questions

1) Does the Greenlee 38524 arbor come with a pilot drill or do I buy that separately?
A replaceable high-speed steel pilot drill is included with the arbor, with a split-point tip so it starts without walking on steel studs or a sheet metal box. The one thing not included is the carbide-tipped pilot drill, which is the one you'd want when running the carbide-grit hole saws through tile or masonry. That's ordered separately.
2) Which Greenlee arbor do I need for a 2 inch or larger hole saw?
Not this one. The 38524 tops out at 1-3/16 inch (30.2 mm) hole saws, so for a 2 inch saw you want Greenlee's large-diameter arbor rather than the .312 hex. Buying by hole saw diameter is what decides it: 9/16 inch through 1-3/16 inch is the 38524's whole range, and a larger saw won't seat on it.
3) My pilot bit snapped on my Greenlee hole saw arbor. Can I replace just the bit?
Yes. The pilot drill on the 38524 is a replaceable high-speed steel bit, so a broken or dulled pilot doesn't scrap the arbor. Pull the pilot and fit a new one rather than buying a whole new arbor assembly.
4) How do I reach a hole saw into a deep wall cavity or through a joist bay with this arbor?
The 38524 accepts Greenlee bit extensions, either the #901 or the #904, which is how you get a small hole saw down into a stud bay or through a deep ceiling assembly without the chuck fouling on the framing. The extension goes between the drill and the arbor, so the arbor keeps driving the saw normally.
5) Will the Greenlee 38524 arbor fit another brand's hole saws?
The 38524 is specified for Greenlee bimetal, recessed light, and carbide-grit hole saws in the 9/16 to 1-3/16 inch range. Match it to Greenlee saws in that size band and the fit is solid with no gap or wobble at the shoulder. Nothing outside that pairing is on spec for it.
6) Is the Greenlee 38524 arbor made in the USA?
Country of origin on the 38524 is the United States, which is the answer a government, healthcare, or education buyer needs when a purchase order carries a domestic-sourcing line.
7) How is the Greenlee 38524 arbor packaged for counter or shelf stock?
It ships as a point of purchase pack, weighing 0.2 lb (91 g) per unit, so it hangs or sits on a retail fixture as-is. Distributors and supply houses stocking it for walk-up trade don't need to repackage it.
