Lenox 1787566 – Frequently Asked Questions
1) Will the Lenox 2-9/16 inch self feed bit run in an impact driver, or do I need a drill?
It has an impact hex shank, so it chucks straight into an impact driver and also holds in a standard drill chuck. The hex shank is what makes bit changes quick on a rough-in day when you are swapping between hole sizes.
2) Can the Lenox 2-9/16 self feed bit bore all the way through a 4x4 without an extension?
Yes. The long shank design cuts through 4 inch by 4 inch material without an extension, which is why it suits drilling plates and built-up framing for electrical and plumbing rough-in. Overall the bit measures 7.2 by 2.8 by 2.8 inches.
3) Is this bit safe to use in old framing with nails in it?
Nail-embedded wood is exactly what the Lenox bi-metal self feed bit is built for. The high speed steel cutting edge holds an edge through hidden nails better than a standard wood bit, which matters on remodel and renovation work where you cannot see what is in the stud. It is not a masonry or metal bit; keep it to wood.
4) Does the Lenox 1787566 come with a spare lead screw?
Yes, every package includes an extra lead screw plus the wrench to change it. The lead screw is the wear part on a self feed bit, so having the spare and the wrench on hand means you are not down when the first screw dulls. Model number is 1787566.
5) Self feed bit or hole saw for running 2 inch conduit and drain lines through studs?
A self feed bit like this 2-9/16 inch Lenox is the better choice for boring framing lumber: the aggressive lead screw pulls the bit through, the flutes clear the chips, and the chamfered edge lets you back it out cleanly. A hole saw is what you reach for in sheet material, metal, or where you need a very shallow cut. For repeated through-bores in wood plates and studs, the self feed bit is faster and takes less effort from the operator.
6) What size hole does the Lenox 2-9/16 self feed bit actually cut?
It cuts a 2-9/16 inch diameter hole. That is a common rough-in size when you need clearance around larger conduit runs or drain piping passing through framing, and the self feed design keeps the hole round and consistent hole to hole.
7) Is the Lenox 1787566 sold as a single bit or as a kit?
It ships as a set: the 2-9/16 inch bi-metal self feed bit together with an extra lead screw and a wrench, under one model number, 1787566. You are buying one cutting diameter, not an assortment of sizes.
