This works really well...
There's actually 2 things here. One is pretty obvious - I used to use my small bench top model drill press to uniform primer pockets and also chamfer the inside and outside of rifle brass. I found a better way to do it was to just pull the power head off the press and flip it upside down on my bench. It makes it easier to see what you're doing, it's a more comfortable motion for doing a lot of brass, and it's really easy to do (just two little set screws hold the tool on the press). I also put 4 little rubber feet on the top of the press's lid so it stays in place. It's really quiet, powerful, etc.
The second thing that works really well, is a brass trap I made for this setup. Using the drill press for any of the brass processing usually made a mess with little brass shavings all over the place. I made this little "trap" out of an empty 1# powder bottle. I cut both the very top and the very bottom off the bottle and taped them together with the top inverted. Then I drilled a hole in the center of the bottom for the cutting tool to go through. When I chuck the tool up in the drill, the plastic is trapped between the cutting tool and the chuck, and so it spins. When I do any kind of operation, the brass falls down into the trap, and the spinning action throws it to the outside walls of the container. It does a great job of catching all little brass shavings and any carbon residue that gets removed.
