Re: Collet 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,
