I have 2 drill holes (3/32") into the side of 6061-T6 tube, and don't have easy access to deburr them. I've been sort of "carving" a chamfer with a small utility knife to remove the burr, but I will have to do this on 500-1000 pieces, so I need something more productive. Any recommendations on drill bits that can will create a burr-free hole? Or any other recommendations on limited-access deburring tools?

Thanks,
-Neil.
