A reciprocating saw includes a housing, a motor positioned within the housing, the motor including a pinion rotatable about a motor axis, and a drive mechanism positioned within the housing and coupled to the motor. The drive mechanism includes a driven gear that engages the pinion and is rotated by the motor, and an output shaft driven by the motor to reciprocate relative to the housing. The output shaft is configured to support a tool element adjacent a forward portion of the housing. The drive mechanism includes a first counterweight coupled to the driven gear for rotation with the driven gear about a rotational axis, and a second counterweight spaced apart from the first counterweight and integrally formed with the driven gear. The first counterweight and the second counterweight are driven by the motor to rotate relative to the housing along a path.

A reciprocating saw includes a casing, a clamping mechanism, a bracket, a first light-emitting piece, and a second light-emitting piece. The casing extends in a front-and-rear direction and forms an accommodation space. The clamping mechanism is disposed at least partially in the accommodation space and configured to clamp an operation accessory. The bracket is disposed at least partially on a front side of the clamping mechanism. The first light-emitting piece and the second light-emitting piece are disposed on a front side of the casing. The first light-emitting piece fits with the bracket and the operation accessory so that a cutting indicator line distributed in an extension direction of the operation accessory is formed. The second light-emitting piece fits with the bracket so that a cutting indicator region perpendicular to the cutting indicator line and extending in an up-and-down direction is formed.

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

A power tool includes a housing, a motor, and a drive mechanism. The drive mechanism includes a driven gear that is rotated by the motor. The driven gear is vertically-oriented within the housing and has an upper portion and a lower portion. The drive mechanism also includes a connecting rod coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the connecting rod to reciprocate relative to the housing through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear for rotation with the driven gear. The counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.

A reciprocating cutting tool reduces dispersion of dust. The reciprocating cutting tool includes a reciprocation converter drivable by a motor, a rod-like slider connected to the reciprocation converter to be reciprocable, a blade holder at the front end of the slider to hold a blade, a power transmission housing housing the reciprocation converter and allowing the slider to protrude from its front end, a cover outward from the power transmission housing, and a fan rotatable together with a rotor in the motor. A first passage of cooling air from the fan is defined between the power transmission housing and the cover. The first passage branches into a second passage toward the blade holder and a third passage not toward the blade holder.

A reciprocating tool with a reduced number of parts is provided. A jigsaw reciprocates a saw blade in a direction along an axis with the power of an electric motor. The jigsaw includes a housing accommodating the electric motor, a guide member fixed to the housing and provided along the axis, a connector member sandwiching the guide member and reciprocating when the power of the electric motor is transmitted thereto, and a plunger attached to the connector member and holding the saw blade.

A motor housing of housings forming an outer casing of a tool main body is provided with two battery attachment portions allowing attachment of rechargeable batteries. The two battery attachment portions are configured as slide attachment type battery attachment portions. The two battery attachment portions are suited to slide attachment type rechargeable batteries that are attached through sliding. The two rechargeable batteries are attached in the right-left direction of the tool main body so that the two rechargeable batteries can be arranged side by side in the direction in which the tool main body extends.

A reciprocating tool easily supplies a lubricant, such as grease (lubricating oil), to a mechanism for reciprocating a slider, and prevents a lack of lubricant. A reciprocating saw as a reciprocating tool includes a motor, a reciprocating conversion mechanism that converts rotation of the motor to reciprocation, a slider connected to the reciprocating conversion mechanism and being reciprocable, and a slider guide that supports the slider in a reciprocable manner and includes a lubricant-passage member in contact with the slider to allow passage of at least part of a lubricant through the lubricant-passage member, and a lubricant reservoir located adjacent to the lubricant-passage member to store the lubricant.

A reciprocating saw includes a housing; a motor, disposed in a housing accommodating space and having a winding extending along a first straight direction; a first transmission wheel connected to the motor; and an input shaft driven by the motor to carry out reciprocating motion. The first transmission wheel is fixed in the accommodating space along a support shaft extending along a second straight direction, and is driven by the motor to rotate about a second straight line; the winding includes a first end and a second end along the first straight direction, a first plane perpendicular to the first straight line passes through a first end face of the first end and a second end perpendicular to the first straight line passes through a second end face of the second end; the first plane is parallel with the second plane, and the winding is located between the first plane and the second plane; at least part of the support shaft is located between the first plane and the second plane.

A hand-held power tool, in particular a saber saw, having at least one holding unit for fastening the hand-held power tool to a holding device, in particular to an arresting cable and/or carabiner clip. The holding unit includes at least one receiving opening for receiving the holding device, and at least one damping element for damping a force transferred from the holding device to the hand-held power tool, in particular to a housing of the hand-held power tool. The damping element includes an at least substantially elastic element that at least partially encloses the receiving opening and receives in a form-fitting manner a fastening part delimiting the receiving opening.
