摘要： A hammer drill comprises a drive mechanism including a spindle, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, and a hammer lockout mechanism adjustable between a first mode and a second mode. The hammer drill further comprises a clutch adjustable between a first state and a second state. The hammer drill further comprises a collar rotatably coupled to the housing and movable between a first rotational position in which the hammer lockout mechanism is in the first mode and the clutch is in the first state, a second rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the first state, and a third rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the second state.

摘要： A rotary power tool includes a housing having a motor housing portion and a handle portion extending therefrom. An electric motor is positioned within the motor housing portion. The rotary power tool further includes a trigger switch configured to activate and deactivate the motor. The rotary power tool further includes a non-contact speed selector switch that is separate from the trigger switch and configured to adjust a rotational speed of the motor. The non-contact speed selector switch is positioned in a foot of the handle portion opposite the motor housing portion.

摘要： A power tool includes an electric motor having an output shaft, a transmission having a transmission housing, a spindle rotatable in response to receiving torque from the transmission and a pinion coupled to the output shaft. The pinion includes a bushing portion, a toothed portion for driving the transmission, and a cylindrical portion between the bushing portion and the toothed portion. The power tool further comprises a fan coupled to the bushing portion of the pinion and a bearing arranged between the cylindrical portion and the transmission housing for rotatably supporting the pinion and the output shaft.

The hammer drill further comprises a clutch adjustable between a first mode and a second mode. The hammer drill further comprises a detent radially movable between a locking position and an unlocking position, and a collar movable between a first rotational position in which the hammer lockout mechanism is in the first mode and a second rotational position in which the hammer lockout mechanism is in the second mode. In the first mode the detent is positioned such that the spindle is moveable relative to the housing. In the second mode the detent is positioned such that the spindle is prevented from moving relative to the housing.
