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.
