Abstract: A rotary hammer adapted to impart axial impacts to a tool bit. The rotary hammer includes a housing, a motor supported by the housing, a spindle coupled to the motor for receiving torque from the motor, causing the spindle to rotate, a reciprocation mechanism operable to create a variable pressure air spring within the spindle, an anvil received within the spindle for reciprocation in response to the pressure of the air spring, the anvil imparting axial impacts to the tool bit, a bit retention assembly for securing the tool bit to the spindle, and an electromagnetic clutch mechanism switchable between a first state, in which the reciprocation mechanism is enabled, such that the anvil imparts axial impacts to the tool bit, and a second state, in which the reciprocation mechanism is disabled, such that the anvil ceases to impart axial impacts to the tool bit.

Abstract: A battery pack that is connectable to and supportable by a power tool (e.g., a hand-held power tool). The battery pack includes a top housing having a support member. The support member of the battery pack top housing is configured or operable to reinforce a support portion of the battery pack that is used to connect the battery pack to the power tool. By reinforcing the support portion of the battery pack, an interface between the battery pack and the power tool is able to withstand greater forces (e.g., from vibrations caused by the power tool).

Abstract: A power tool having a housing, a motor, a tool holder driven about an output axis by the motor, and an output element for performing an operation on a workpiece. The tool holder has a locating feature including a tapered portion becoming narrower in a direction away from the surface of the tool holder. The output element has an aperture for receiving the locating feature and a face facing the surface of the tool holder when the locating feature is received. The power tool also includes a flange for transferring a clamping force for urging the output element towards the tool holder and a tab projecting from the flange for finger tightening the flange. A biasing member provides the clamping force toollessly. A gap is defined between the surface of the tool holder and the face when the tapered portion of the locating feature is fully received in the aperture.

Abstract: A stand-alone motor unit for use with a piece of power equipment includes a housing and a flange coupled to the housing on a first side thereof. A plurality of apertures through the flange defines a first bolt pattern that matches an identical, second bolt pattern defined in the piece of power equipment. An electric motor has a power output of at least about 2760 W. The motor includes a stator having a nominal outer diameter of up to about 80 mm and a rotor supported for rotation within the stator. A power take-off shaft receives torque from the rotor and protrudes from one of the flange or a second side of the housing. A controller is positioned within the housing and electrically connected to the motor. A battery pack for powering the motor has battery cells having a nominal voltage of up to about 80 V.

Abstract: A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.

Abstract: A rotary power tool comprises a motor, an output shaft that receives torque from the motor, a clutch positioned between the motor and the output shaft for selectively engaging the output shaft to the motor, and a transducer for detecting an amount of torque transferred through the clutch to the output shaft. The clutch is capable of being actuated from a first mode in which the output shaft is engaged to the motor, to a second mode in which the output shaft is disengaged from the motor, in response to feedback from the transducer of the detected amount of torque transferred through the clutch.

Abstract: A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

Abstract: A power tool includes a housing and a motor disposed in the housing. The motor has an axial face and a motor shaft extending from the axial face. The power tool also includes a spindle driven by the motor about an output axis, a motor plate having a central opening defining an inner surface of the motor plate, and a tolerance ring coupled to the inner surface of the motor plate. The tolerance ring has deformable waves. The motor plate is coupled to the motor by engagement of the deformable waves with the motor to take up tolerances between the motor plate and the motor.
