With those items, it's probably primetime to get a Black Cleaver or a Last Whisper, the former when your enemies don't have much armour and latter when they're getting a fairly large bit. Depends on the champion, of course, since Corki can probably always just get a Black Cleaver to shred squishies' armour with his Gatling Gun, but that's probably a good guideline for your described situation.
