This thing is 13" long and the part that fits into something is 1 1/2" of it.  The only thing it has marked on it is "Made In USA" and "Do not use in drill press".
Thanks,

 (hand drill) Extension for drill or driver bits..

It is for use with a hand drill, not an electric drill, right? 
Thanks,
Barb

Electric hand drill OK (light duty). just not a drill press (too much torque on press)

Still see some in the hardware store, Stanley I believe.   Real handy tool, have 2 of them. 

Very often used with flat bits for site work when boring long holes through wooden beams etc... I also have one with a much larger (1/2") bore - could be used with Forstner bits, but not many other drill have a shank to suit...

Now this is handy for me!  I have three or four drill extensions, up to 2 feet long, as well as one identical to Barb's.  I have to drill a hole, 1 1/4 inch diameter, for the bellows I'm making.  Got a Forstner bit, but it's not long enough.  But with an extension it is!  Don't know why I didn't think of that; good thing you did the thinking for me, Billman!

Thanks so much for all the replies.  Any idea if this is a good item for eBay or not and what the value used might be?

since you can buy a new one for $10 and they are a $1 garage sale item you have to decide.

That's what I needed to know.  Thanks!

I've got one inside one wall of my house.  When I did the electrical rewiring of the house, I would stack two, even three, of them, to drill through firestops to run the light switch wiring.  One trouble with that design is the set screws can work loose, releasing the bit, or, in my case, the bit and the first extension, which now reside somewhere in that wall, to be found by whoever (and it may be me) opens up the wall next.

Newer designs use spring-loaded collars, like Yankee screwdrivers - far superior.

Grind a couple of small notches where the screws sit, and tighten well with an Allen key. If using with a Forstner bit remove very frequently to clear the hole, or shavings will compact behind the cutter, and it will jam....
