Just about any kind of oil will work and makes working on metal so much easier.
I have used those before and it was not worth it over a dremel. I still left a burr and caused the barrel to get squished every so slightly.
Dremel and coutersink is the best way to go.
So just have the barrel secure with a flat edge and dremel it to the right length?
