Have these experts drilled the world's smallest hole?

Experts at Cardiff University have developed machinery so sophisticated that they can drill a hole narrower than a human hair. Researchers at the University's Manufacturing Engineering Centre are drilling holes as small as 22 microns (0.022 mm) in stainless steel and other materials. Such precision has potentially major benefits in medical and electronic engineering. more @
