I am working on a bunch of projects nearly all of which involve 1-1/2"x.120 wall
square steel tube. After I cut it on the abrasive chop saw, it's easy to whip
off the external burrs with a flap disk. But on some of these pieces I also need
to do an internal deburr, and I don't have time to use a file, it would take way
too long. What are some tools/procedures to do this?
