Turning & milling beryllium is no problem. Drilling can be a bitch. Keep in mind, beryllium will move around as you take the skin of the material off. Also, be careful to take precautions with beryllium. You want to make sure you machine wet & avoid slivers in your skin. Grinding & welding are by far the most dangerous.
