ABSTRACT:
A screwdriver includes a power driven spindle (50) having an end face (52), an enclosure defining a closed cavity (70, 24, 14), a sleeve (60) having a central bore (70) communicating with said cavity and having a forward opening (70c) to receive the head (94) and part of the thread of a threaded fastener (90), and a vacuum (86, 88) for lowering the pressure in the cavity and continuously drawing air from the forward end of the sleeve past the head while holding the head while the fastener is held in a forward end portion (60a) of the sleeve and without driving the spindle. The spindle drives the fastener forwardly and into a workpiece (96) and an air path (70d, 70c, 70b, 70a) sucks contaminants rearwardly and from the workplace.
