Lenox 1787561 – Frequently Asked Questions

1) Will a 1-1/2 inch Lenox self-feed bit run in an impact driver, or do I need a drill?
It has an impact hex shank, so it drops straight into an impact driver's 1/4 inch hex collet or into a drill chuck or hex bit holder. The hex shank is what lets you swap it quickly and keeps it from spinning in the chuck under the torque a 1-1/2 inch self-feed bit generates.
2) Can this bit drill all the way through a 4x4 without an extension?
Yes. The long shank on the Lenox 1-1/2 inch self-feed bit is made to cut 4x4 lumber without adding an extension. Overall the bit measures 6.9 inches on its longest dimension, which is where that depth comes from.
3) Will this bit survive hitting a nail in an old wall?
Bi-metal construction is the reason to pick it for remodel work. The body is flexible carbon steel with a high speed steel cutting edge welded on, which is what handles nail-embedded wood without the edge chipping out the way a plain steel spade or auger bit does.
4) Is a 1-1/2 inch self-feed bit big enough for running romex and conduit through studs?
A 1-1/2 inch hole is a common electrical bore for bundling cable runs or passing conduit through wood framing, and that is exactly the work this bit is built for: holes for conduit, wiring, and box installations in wood studs and joists. For smaller single-cable runs you would step down to a smaller diameter in the same self-feed family.
5) What is the difference between a self-feed bit and a hole saw for 1-1/2 inch holes in framing?
The self-feed bit has an aggressive lead screw that threads into the wood and pulls the bit through, so you supply very little push pressure and the screw controls the feed rate. Flutes clear the chips as it goes. A hole saw leaves a plug you have to knock out of the cup every hole. For repeated through-holes in studs and joists the self-feed is faster; a hole saw is the better choice when you need to cut materials other than wood.
6) What part number should I order for the Lenox 1-1/2 inch bi-metal self-feed bit?
Order Lenox MPN 1787561. That is the 1-1/2 inch diameter bi-metal self-feed wood bit with the impact hex shank.
7) Does the bit get stuck in the hole after it breaks through?
The chamfered edge is there for that. It lets the bit back out of the hole cleanly once the cut is finished, with minimal tear-out around the rim of the hole.
8) Is anything else included in the box, like a battery or an extension?
It ships as the bare bit only. No battery is included, and none is needed since the bit itself is a non-powered accessory. No extension comes with it either, though the bit is long enough to clear a 4x4 on its own.
9) How heavy is this bit, and will it throw off a cordless impact in tight joist bays?
It weighs 0.64 lbs, so it adds very little to the tool in overhead or between-joist work. The bulk of the length is the shank, 6.9 inches overall with a 1.7 inch cutting head footprint.
