Hi Matt

Have had excellent success using Dremel tools and some of their truncated
cone shape carbide cutters.  Most skilled rework/repair operators can pick
up this type operation with a minimum of practice.  I recommend using some
sort of template or 1:1 visual aid to avoid cutting the wrong trace on
densly populated boards.

Using a small 2 flute endmill and a milling set-up also works well, space
permitting.

Regards - Kelly
