The Pistol-Grip Tool (PGT) is a computer controlled [[power tool]] designed by NASA for use in space to operate as drill and screwdriver.  It was designed for use to repair the [[Hubble Space Telescope]] and was first used in 1997 and has since become standard equipment for space EVA servicing missions.  It features high torque that turns at a deliberately slow speed to be controllable in space.  Astronauts can pre-set the speed, number of turns, direction, and other features for each task which it will record all actions and settings for future reference.
