Does anyone know of a source for sets of high-quality micro-sized drill bits? All I can find online are the very cheap Chinese-made sets. Those tend to be poorly made and very fragile.
I have two sets of micro-sized numbered bits that I got years ago from Micro-Mark, but they're not metric. I know there are close equivalents in the number range to metric bits, but would like to have all sizes on hand. Of course, I would want them in some kind of index because it's impossible to read the sizes on the bits as they get smaller and smaller...
Not sure where you are based, but if its UK, try Allan at . He sells (in sets or individually) very fine drill bits. The smallest I have is 0.3mm. They are very sharp, but rather brittle and all have a shank about 3mm in diameter (on which you can read the size, though faintly and sometimes very small). With that shank, you can hold them in your fingers and drill away without needing a drill. They are not, however, as long ss conventional steel drill bits.
