What I do to get a clean hole in tube is to drill a millimetre under size and open the hole with a slot mill, you need a milling machine for this. This will still leave a burr but very small. Also try pushing a tight fitting piece of dowel down the barrel to the point where the hole will be, that way the edge of the hole will be better supported so resisting the cutting forces.
