Greenlee 39893 – Frequently Asked Questions

1) Which Greenlee arbors does the 39893 pilot drill fit?
The Greenlee 39893 pilot drill is made for Greenlee arbors #37154, #37155, #37156 and #38522. If your arbor is one of those four, this is the correct replacement pilot. For any other arbor, check the pilot size that arbor calls for before ordering, since a pilot that does not seat in the arbor collar will not hold center.
2) What size is the Greenlee 39893 pilot bit, and how long is it?
It is a 1/4 inch diameter pilot with a 3-1/4 inch overall length. That length is what sets how far the pilot can lead the hole saw before the saw teeth contact the work, so if your arbor originally shipped with a 3-1/4 inch pilot, this drops straight back in.
3) Is this just the pilot drill, or does it come with the arbor and hole saw?
Pilot drill only. It is sold as a replacement part for an existing Greenlee arbor assembly, so you supply the arbor (#37154, #37155, #37156 or #38522) and the hole saw or cutter yourself.
4) What is the Greenlee 39893 pilot bit made of, and will it hold up drilling steel studs and panels?
High-speed steel. HSS holds its edge at the heat generated in metal drilling, which is why it is the standard pilot material for electrical work in sheet steel, enclosures and panel boxes. Run it at a speed and feed suited to the material and keep it cool to get the life out of it.
5) Can I use a hardware store 1/4 inch twist drill in my Greenlee arbor instead?
Not reliably. The 39893 is cut to a 3-1/4 inch overall length to match the pilot projection those four Greenlee arbors (#37154, #37155, #37156, #38522) are built around. A general-purpose 1/4 inch bit of a different length either projects too far past the saw teeth or does not reach, and the shank may not clamp correctly in the arbor set screw flat.
6) How do I stock this for a service truck, and how much does one weigh?
Each pilot drill weighs 0.200 lb (91 g) and ships in standard packaging as a single piece, one model number, 39893. Carrying two or three on the truck is common practice because the pilot is the part of an arbor set that dulls or snaps first, and a broken pilot takes the whole hole saw out of service.
