My deep boring is usually bronze. witch with light cuts works fine. I don't except to use the full length. The bars out there are 14" with is fine This was 18"" so I just left it.
The bar will flex. They all do. Even a good sized solid carbide bar with minimal overhang will still deflect under load (it has to). Managing deflection is called "machining".
When boring I generally set the tool slightly above center, then as it deflects the load is slightly reduced.
