I have the tool that will work on the portion that is away from the wall, but I cannot see how to deburr next to the wall. It seems that you might damage the inside wall while trying to deburr this area. Any suggestions? Has anyone seen a video showing a possible solution to this deburring issue? Thank for your time and any suggestions in advance.
