A tiny but powerful new lightweight drill has been developed by space scientists and engineers. It expands the fields in which drilling has been difficult in the past. The new drill could be used in the drilling required during surgical or diagnostic procedures involving bones, or when extracting heart pacemaker leads. Future space missions could include drilling for rock and soil samples, using only lightweight landing vehicles with robotic arms.
The color photo shows the new driller penetrating a sandstone while the drill is held only from its power cord. Relatively small vertical force is used in this application -- a factor that will be useful when the drill is used in future space missions and weight needs to be kept to a minimum. The drill is driven by piezoelectric devices, which have only two moving parts but no gears or motors. Piezoelectrics are materials that change their shape under the application of an electrical field. The drill can be
A. be used in space missions.
B. pull out the heart pacemaker leads.
C. replace the conventional rotary drill.
D. drill the bones during procedures of medical treatment.
