A power tool includes a housing, a power output element for outputting power, a motor for driving the power output element to output power, and a surface light source device for providing illumination. The surface light source device is mounted on the housing and the surface light source device includes a light exit surface allowing the surface light source device to emit light.

A power tool and method for heat management using speed control. The power tool includes a housing, a motor within the housing, and an electronic processor coupled to the motor. The electronic processor is configured to operate the motor at a first speed corresponding and determine whether the power tool has been unloaded for a predetermined amount of time during which the motor has been operated at the first speed. In response to determining that the motor has been unloaded for the predetermined amount of time, the electronic processor operates the motor at a second speed lower than the first speed. The electronic processor further determines whether the power tool is loaded while operating the motor at the second speed and operates the motor at the first speed in response to determining that the motor is loaded.

A reciprocating saw includes a housing, a motor, and a drive mechanism. The motor is configured to operate in a forward mode corresponding to a first rotational direction, and in a reverse mode corresponding to a second rotational direction opposite the first rotational direction. The drive mechanism includes a driven gear, a connecting rod, an output shaft, and a counterweight. The driven gear is rotated by the motor and has an upper portion and a lower portion. The output shaft reciprocates through a cutting stroke and a return stroke. The counterweight is coupled to the driven gear and rotating with the driven gear. When the motor is operated in the forward mode, 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 power tool includes a housing, a power output element for outputting power, a motor for driving the power output element to output power, and a surface light source device for providing illumination. The surface light source device is mounted on the housing and the surface light source device includes a light exit surface allowing the surface light source device to emit light.

A transmission device is configured to generate at least one of a stroke motion and a reciprocating motion of an insert tool of a hand-held power tool, and includes at least one link unit configured to generate the stroke motion. The link unit includes at least one output element, at least one link element, at least one contact surface, and at least one further contact surface. The at least one contact surface is disposed at least partially on the at least one output element. The at least one link element is configured to act in combination with the at least one output element via the at least one contact surface. The at least one further contact surface is configured to generate a force that initiates the reciprocating motion, and is disposed at least partially on the at least one output element.

A reciprocating power tool may include a driving system including a motor and a transmission received in a housing to drive a reciprocating mechanism. A counterbalance mechanism may be coupled between the driving system and the reciprocating mechanism. The counterbalance mechanism may include a rotating counterbalance mechanism including a first rotating counterweight member and a second rotating counterweight member coupled to an output gear of the driving system. The counterbalance mechanism may include a rocking counterweight member coupled between the output gear and the housing. The output gear may include a recessed portion in which the first rotating counterweight member and a clutching system are received.

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.

A reciprocating saw blade is provided including a blade cutting edge including a plurality of teeth and a plurality of gullets. At least a portion of the plurality of teeth each includes a rake face, a relief face, a tooth cutting edge, and at least one non-cutting tooth edge extending on a first side face transverse to the rake face and the relief face, and a second side face opposite the first side face and transverse to the rake face and the relief face, a first relief-side edge at a junction between the first side face and the relief face, and a second relief-side edge at a junction between the second side face and the relief face. At least one of the first and second relief-side edges includes a modified portion extending rearward from the rake face.

A reciprocating saw includes a housing, a motor positioned within the housing, a drive shaft defining a longitudinal axis, and a spindle positioned substantially within the housing and coupled to a wobble plate. The spindle includes a throughbore formed by a flow welding process, wherein the throughbore extends through the spindle to receive the wobble plate.

A system includes at least one first machine tool having at least one first receiving device for at least one insert tool, at least one storage device, and at least one external unit. The at least one insert tool is configured to be arranged on the at least one machine tool. The at least one storage device includes at least one second receiving device for the at least one insert tool. The at least one external unit has at least one external input interface. At least one application-specific parameter of at least one output is generated from an input, which is transmitted to the at least one machine tool, to the at least one storage device, and/or to other external units.
