I would think so unless I am missing something. --- End quote --- I'd go with this option. A 1/2" slot drill will do the trick. The problem with a boring bar would be getting into the centre of the bottom of such a small hole. |

I searched ebay and found micro boring bars for $15 shipped, and they're carbide as well. |

It can rarely (if ever) be well sharpened. Well hardened and tempered tool steel is (almost always) superior to carbide for this type of cutter. |
