I think it may be a knock out as one end is brass, and there is no obvious way to set a stop depth. But, I do not believe there is a need to knock out anything with a 3C collet. Might be for some other tool. Although it fits nicely inside of the draw tube, and is about 6-inches longer.
Thanks for the insight,

The long rod next to the draw bar appears to be either a knock out bar to remove tight fitting stock in a collet, or a collet stop. As a stop, it would be inserted into the draw bar, and into the collet, and locked in place to index material being bored to a specific depth.
I would be interested if any of those collets turn out to be 6K.
This is a great forum.
Best of luck,
