and go gently. Most people I see using tubing cutters apply too much 
pressure, or try to cut too deeply

I prefer the machinist's deburing tool, but a fine rat tail file works 
great. I'm talking about the size and type for sharpening chain saw chains.

and you don't want that embeded into the end of the tube or rolling around 
loose in there.
