    Abstract: A chuck for a power tool includes a chuck body extending along a longitudinal axis. The chuck also includes a plurality of jaws, each with a jaw end, and each movable along a respective jaw axis between a closed position and an open position. Each respective jaw axis is oriented at an oblique angle relative to the longitudinal axis. A biasing member is coupled to the jaws and is operable to bias the jaws toward the closed position. The biasing member includes a spring. The chuck also includes a rotating assembly selectively engageable with the jaws such that, when engaged, the jaws are movable in response to rotation of the rotating assembly. The biasing member includes a guide sleeve coupled to each of the jaws and movable axially along the longitudinal axis in response to each of the jaws moving along its respective jaw axis.

    Abstract: A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, and an anvil received within the spindle for reciprocation in response to reciprocation of the piston. The anvil imparts axial impacts to a tool bit in response to reciprocation of the piston. The rotary hammer also includes a bit retention assembly for securing the tool bit to the spindle. The bit retention assembly includes a collar with an indicator thereon. The indicator is at least partially visible to a user of the rotary hammer when the tool bit is improperly inserted within the spindle.

    Abstract: A powered dispensing tool includes a housing, a motor positioned within the housing, a rack coupled to the motor for powered translation in at least one of a forward direction and a reverse direction, and a transmission selectively coupling the motor and the rack. The transmission includes an input ring rotatable in response to rotation of the motor in a first direction corresponding with powered translation of the rack in the forward direction, a first clutch member engaged with the rack through an intermediate gear, and a second clutch member that receives torque from the input ring and that is movable in response to rotation of the motor in the first direction toward a first position engaging the first clutch member. The second clutch member is also movable in response to rotation of the motor in an opposite, second direction toward a second position disengaged from the first clutch member.

    Abstract: An electrical tool includes a trigger lock assembly having a trigger lock member, a detent assembly, and a return spring. The trigger lock member is movable relative to a trigger between a neutral position, in which the trigger is movable between an off position and an on position, a lock-off position, in which the trigger is prevented from moving from the off position, and a lock-on position, in which the trigger is maintained in the on position. The detent assembly is operable to releaseably retain the trigger lock member in each position and includes a recess associated with each position. The detent assembly also includes a projection selectively engageable in one of the recesses to releasably retain the trigger lock member in the associated position, and a biasing member biasing the projection into engagement. The return spring is operable to bias the trigger lock member toward the neutral position.

    Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position toward a driven or bottom-dead-center (BDC) position, a gas spring mechanism for driving the driver blade toward the BDC position, a lifter assembly having a rotary lifter for returning the driver blade from the BDC position toward the TDC position, a motor that provides torque to the rotary lifter to return the driven blade from the BDC position toward the TDC position, and a cam which, during operation of the rotary lifter, causes the rotary lifter to axially move along a rotational axis defined by the rotary lifter between a first position, in which the rotary lifter is engageable with the driver blade, and a second position, in which the rotary lifter is not engageable with the driver blade.

    Abstract: A rotary power tool may include a main housing, a motor positioned within the main housing, a handle extending from the main housing, a trigger that is configured to activate the motor when depressed, and a control board disposed within the handle and including a microcontroller (MCU), a first Hall sensor, and a second Hall sensor. The trigger includes a trigger body, a holder fixed to the main housing, the trigger body being movable relative to the holder along a longitudinal axis, an arm fixed to the trigger body and having a magnet holder that receives a magnet, and a spring for biasing the trigger body away from the holder. The first Hall sensor and the second Hall sensor are configured to detect depression of the trigger and emit signals to the MCU for controlling operation of the motor.
