Lenox 3084655X – Frequently Asked Questions

1) What shank size does the Lenox extension shank need in my drill?
It uses a 1/2 inch shank, so you need a drill chuck that accepts 1/2 inch. Lenox describes it as an impact hex shank design, which lets you swap bits without extra tools.
2) What lengths does the Lenox extension shank come in?
Two lengths, 5-1/2 inch (MPN 3084655X) and 12 inch (MPN 3084712X). The 5-1/2 inch handles standard framing depth; go to the 12 inch when you are reaching through stacked members or drilling from outside a wall cavity.
3) Can I drill through a 4x4 with this without adding another extension?
Yes. Lenox states the longer shank design lets you cut through 4x4 material without requiring additional extensions. The aggressive lead screw tip pulls the bit through, and the flutes clear chips as you go.
4) Will it hold up drilling through old studs with nails in them?
That is what the high speed steel cutting edge is for. Lenox specifies it for nail-embedded wood, where standard tools dull or fail, and the HSS holds an edge through the heat of repeated deep holes. Useful on remodel and retrofit work where you cannot see what is inside the framing.
5) Does anything come in the box besides the extension?
Each unit ships with an extra lead screw and a wrench, so you can replace a worn or bent lead screw on the job instead of losing the tool for the day.
6) Is this the right tool for running electrical wire through joists and studs?
Yes, that is its main use. The extension gets a bit deep into wall studs and floor joists for wire routing, and the same reach works for pipe and small duct penetrations in tight cavities. It is a non-powered accessory, so it goes in the chuck of your own drill.
7) Do I still need a separate bit, or does this cut on its own?
You need a cutting bit. The extension mounts in the chuck and the bit attaches to the extension using the included hardware; the extension only adds reach and carries the lead screw tip.
8) How wide is the Lenox extension shank body?
Product width is listed at 1.1 inches, so it clears bored holes and passes through framing without hanging up behind the cutting bit.
