Perhaps less chance of corrosion and smoother when interacting with cork? Maybe.

Maybe. ^^^^^^^^^^^^^^^^^^ "Cork" borers are called that, even though they are now usually used to bore holes in rubber stoppers. It's kind of like "dialing" a touch-tone phone. Brass? I think that's because the tooling required to sharpen steel "cork"-borers would be out of place in a chem lab, and brass works well enough.
