BulkHead Installation (Burr's)

[Br3wBee]

I just drilled my first 7/8 hole using a step down drill bit on my SS Bayou Classic 8 Gal pot and I have some decent size burr's on the inside of the pot. Anybody else run into this problem or does anyone know how to take that off. Things I was thinking were a dremmel with a grinder bit or metal files to do by hand. Thoughts? Suggestions?

I took my step bit and ran it very briefly on the inside of the pot at the end of the cut to clean up and then cleaned with a grinder wheel on a dremel. 5 minutes tops. If you go to brewhardware.com, Bobby has videos of how to cut holes and install various mods to kettles and pots that are good, and I got that tip from him.
