A power tool (10) includes a housing (12, 14), a motor (26), an output member (11) driven by the motor, and a reaming attachment (214) coupled to the output member. The reaming attachment has a front end portion selectively driven in rotation by the output member (11) to drive a fastener into a workpiece, and a reaming portion selectively driven in rotation by the output member to remove material from an end surface of a conduit. A rotational motion sensor (22) in the housing (12, 14) is operable to detect rotational motion of the housing about an axis. A controller (24) receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing (12, 14), and drives the motor in a direction corresponding to the direction of rotational motion of the housing.

A power tool is provided including an electric motor and a tool housing arranged to house the motor. The electric motor includes a stator, an armature rotatably with respect to the stator and having an armature shaft, and a fan rotatably attached to the armature adjacent the stator. The fan includes blades each having an angled side edge such that a longitudinal length of each blade is smaller at an outer periphery of the fan than at an inner edge of the fan blade near the armature shaft. The tool housing includes an annular rib disposed around a periphery of the housing in close proximity to the fan. The annular rib has an angled surface substantially parallel to the angled side edges of the fan blades to redirect airflow generated by the fan in a centrifugal direction of the power tool.

A tool (10) with a transmission assembly (18) having a reduction gearset (106) and a speed selector (108). The speed selector has a member (240), an actuator (242) and a shifter assembly (244). The member (240) is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator (242) includes a pivoting yoke (260) and a follower (262) that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly (244) has a selector switch (300), a switch fork (304), and a pair of springs (306, 308). The selector switch is slidable between a first switch position and a second switch position. The shift fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the shift fork relative to the selector switch into a neutral position.
