This is my workplaces full time deburring machine, however I have no idea why it has 2 heads. The second one was obviously and was an afterthought and it is slapped together. it was originally a craftsman drill press. does anybody know the reasons when it has a second head, and if so does your shop have similar drill presses.

It's a countersinking drill. Drill your hole and immediately countersink without changing bits.

Someone was just tired of changing bits 1000 times a day.

Does it actually travel down with the quill or is it stationary? It's obviously powered by the belts. My guess is it's a 2nd op quill and that one is either pops out slugs that have been cut but may leave hanging Chad, or it's simply a smaller deburrer than what's in the main quill.

The second head does not have a movable quil

Maybe they wanted a rough bit that they could apply side loads to without damaging the bushings in the main shaft. Having damaged bushings makes accuracy very difficult.

Also a Jacobs chuck isn't really meant to take side loads... guess how I know?
