Hello. When I make PCBs for homebrew projects, I often use a Dremel
Moto-Tool with a dental bur for cutting the pattern into the copper
foil. About ten years ago I bought a bunch of burs from someone at the
Dayton Hamvention. Now they're worn out, and I'd like to get some more.
Does anyone know where a hobbyist can buy these things? See photo at
