BUNGARD doesn't look like a boardhouse, it looks like an equipment manufacturer.
The very small mill bits have severe cutting rate and handling precautions. You have to move them very slow. You have to use an optical tool end detector because the regular one will break them. There are vibration restrictions and even handling precautions - they break if you drop them on the floor, for instance. The REALLY small ones break if they fall over from standing on end on a hard surface.
