Unless you are doing BGA, a regular bit and iron is fine. With a good mag-lamp!
However leaded SMD IC removal is best done by cutting at body with sharp knife, wipe off dead legs and reflow new IC leads with a dry clean iron, even three leads at once. Optionally glue in place and reflow two diagonal corners first.
I use a hand magnifying lens and bright torch angled suitably to read what it says on laser etched part IDs. The white paint is easier.
