Lenox 1779801 – Frequently Asked Questions

1) What is the Lenox 1779801 arbor actually for, and does it come with the pilot bit?
It's the arbor assembly that mounts a hole saw to your drill, and the 4-1/4 inch split point pilot drill bit is part of it. The pilot goes in first, establishes the center, and keeps the saw from walking before the teeth engage the material. You supply the hole saw; the arbor and pilot bit are what you're getting here, ordered as model 1779801.
2) Will this Lenox arbor fit any hole saw, or only certain sizes?
It's a 2L arbor, so it mates with hole saws set up for the 2L arbor size. Grab a saw that calls out 2L compatibility and it threads on correctly. A hole saw built for a smaller arbor size won't seat on this one, so match the arbor callout on the saw before you pair them.
3) Is a 4-1/4 inch pilot long enough to get through a doubled-up stud or a thick wall plate?
The pilot itself is 4-1/4 inches long, but only 1.25 inches of that is flute. Flute length is what governs chip clearance and practical cutting depth, so figure this for standard-depth work where the hole saw body carries the cut, not for deep drilling through stacked lumber. Overall the assembly measures 5.6 inches long by 2 inches wide by 1.9 inches high.
4) Can an electrician use this for running conduit and setting junction boxes?
That's the main use case. The 2L arbor with its split point pilot is aimed at conduit runs, junction box openings and component mounting, and the same setup handles pipe routing for plumbing and duct or equipment penetrations on HVAC work. The split point bites on contact instead of skating across the surface, which matters when you're laying out box locations on a stud face.
5) What is the pilot drill made of, and will it hold up in framing lumber all day?
Hardened carbon steel. That's the right material for wood framing, drywall and general construction hole cutting, where it holds a sharp edge through repeated holes. Carbon steel is not the choice for cutting hardened metal, so if you're going into steel studs or thicker metal, plan on a bi-metal setup rather than this one.
6) Why does my hole saw wander when I start the cut, and will this pilot fix it?
Wandering usually comes from a dull or conventional pilot point that skates before it bites. The split point grind on this Lenox pilot starts cutting the instant it touches, which holds the center where you marked it. Start at a moderate speed, let the pilot fully penetrate before the saw teeth reach the material, then keep pressure and speed steady through the cut.
7) How heavy is the Lenox 2L arbor, and does it need any power or battery?
It weighs 0.542 lbs and takes no power of its own, no battery included and nothing to charge. It's a straight mechanical accessory that chucks into whatever drill you already run. Light enough that it won't throw off the balance of a cordless drill overhead.
8) Is there a Prop 65 warning on this Lenox pilot bit arbor?
No generic Proposition 65 warning is carried on the 2L arbor with the 4-1/4 inch pilot drill. Worth knowing if you're buying into a California facility or institutional account where labeling gets logged.
