I've thought of that a few times but never tried it. I might now!

For deburring larger circular holes and rectangular holes, I use these deburring tools. The pivoting cutter is double edged as so suits left and right handers. The cutters are replaceable when they loose their edge. I wouldn't be without them.

The picture shows a cheap and cheerful plastic handled version and a nicer metal one.
