I was going through an old pile of auger bits looking for one to fit my power drill and ran across a unique specimen. This 18" double-helix auger is equipped with a brace end but also has a threaded portion. I've looked closely but cannot find a maker's mark or brand. It seems to me the thread is manufactured in rather than home built because the brace taper looks complete. I only found threaded drill bits referenced for impact usage and I don't think this is that.
Anybody got some more information on what this is intended for? Worth anything?

Is it possible that someone threaded it for a specific purpose?
Obviously not as old, but treaded drill bits used in aviation a lot. 10-24 was the thread size for most of them.
Or, they can then be threaded into a "T" handle..

That is it. They are called a barn auger bit. Normally the square taper was forced into a hole in the handle and pulled tight with the nut. Roly

YES! This being a barn auger bit on a handle makes complete sense. I don't need to use that but will display it.

^ This - a bit that large needs more leverage than your standard brace can deliver comfortably so T handle can make the going a little easier.
