Lenox 1779803 – Frequently Asked Questions

1) What size hole saws does the Lenox 4L arbor fit?
The Lenox 4L standard arbor takes hole saws in the 9L through 19L range. That covers the mid-size cups an electrician reaches for on device boxes and conduit runs. Anything smaller or larger than that range needs a different arbor size, so match the cup to the 9L-19L window before you buy.
2) Will a 1/4-inch shank arbor work in my cordless drill?
The shank on the Lenox 4L arbor is 1/4 inch, so it chucks into any standard 3/8 inch or 1/2 inch keyless drill chuck with room to spare. It is a round shank going into a chuck, not a quick-change hex bit holder, so tighten the chuck firmly on it before you load a large cup.
3) Does the Lenox 4L hole saw arbor come with a pilot drill, or do I order that separately?
A split point pilot drill is part of the arbor. The split point starts on contact instead of skating across the surface, which is what keeps the hole where you marked it when you are cutting a device box opening in a stud face or a panel. Nothing extra to order to get drilling, just the hole saw cup itself.
4) Is the Lenox 4L arbor strong enough for daily production work, or is it a homeowner arbor?
Hardened carbon steel is the construction, which is the material spec that decides whether an arbor twists or the pilot dulls after a few dozen holes. It is built for repeat trade use, drilling conduit and box openings in wood, drywall and composites. The pilot is a carbon steel drill, so it is at home in those materials rather than in steel plate.
5) How much room do I need behind the wall for a Lenox 4L arbor and hole saw?
The arbor measures 5.6 x 1.9 x 1.9 inches, and the 5.6 inch figure is the overall length you are feeding into the chuck plus the pilot reach. In a tight ceiling bay or between studs, add your hole saw cup depth to that and the drill body behind it before you commit to drilling in place.
6) What is the Lenox part number for the 4L standard hole saw arbor with the 1/4-inch shank?
Lenox part number 1779803 is the 4L standard arbor with the 1/4 inch shank and split point pilot drill. That is the number to quote on a reorder or a stocking line so you get the 4L configuration rather than one of the other arbor sizes in the family.
7) Is there a Prop 65 warning on the Lenox 1779803 arbor?
No Prop 65 generic warning applies to the Lenox 4L arbor, model 1779803. For institutional and government purchasing that screens hardware submittals on Prop 65 status, that is a clean line on the form.
8) How light is a hole saw arbor for stocking a service van kit?
At 0.183 lbs the 4L Lenox arbor adds essentially nothing to a bit case, which is why most service techs carry one arbor per size range rather than swapping pilots. Keep it paired with the 9L-19L cups it drives and the kit stays sorted.
