ZURICH, Switzerland (AP) -- A renowned Swiss scientific institute says it has built a drill that spins at least twice as fast as any motor currently in existence.
The Federal Institute of Technology in Zurich says the matchbox-sized device uses custom-made electronics and a new combination of metals to achieve a million rotations per minute.
Researcher Christof Zwyssig said Friday the engine will allow them to drill holes narrower than the width of a human hair.
He and fellow postgraduate researcher Martin Bartholet are marketing their device to the electronics industry.
Institute faculty and students have won 21 Nobel prizes.
