A reciprocating saw includes a housing including a handle defining a handle axis extending centrally through the handle from a first end to a second end of the handle, a battery receptacle located adjacent the second end of the handle, a battery insertable into and removable from the battery receptacle along a battery axis, a motor powered by the battery and including a motor shaft rotatable about a motor axis, and a spindle configured to reciprocate along a spindle axis in response to rotation of the motor shaft. The spindle axis is parallel to the motor axis.

Providing a reciprocating tool capable of reducing vibrations generated during operations and improving work performance and processing precision. A reciprocating tool includes a transmission gear part 61 and a counter weight part 62. The transmission gear part 61 includes a bevel gear 611 and a weight 611A. The bevel gear 611 is rotatable in a first direction about an axis B by receiving a drive force of a motor 3. The weight 62A is rotatable in a second direction opposite to the first direction about the axis B by receiving the drive force of the motor 3. A center of gravity 61G of the transmission gear part 61 and a center of gravity 62G of the counter weight part 62 are separated farthest from a blade mounting part 8 when the blade mounting part 8 is positioned in a rearward position. The center of gravity 61G of the transmission gear part 61 and the center of gravity 62G of the counter weight part 62 are closest to the blade mounting part 8 when the blade mounting part 8 is positioned in a forward position.

There is a hand-held machine tool, in particular a saber saw, with a housing, a drive motor with an output shaft, a spindle for receiving a tool, in particular a saw blade, and a motion converter for converting a rotational motion of the drive shaft into a reciprocating motion of the spindle. The motion converter comprises an eccentric element driven by the output shaft rotationally about an axis of rotation with a driver part arranged eccentrically to the axis of rotation, and a pendulum element which is mounted pivotably about a bearing point and is connected via a coupling point to the spindle. The pendulum element has a guide element for guiding the driver part. In one embodiment, the guide element is arranged between the bearing point and coupling point.

A reciprocating saw includes a housing defining a motor housing portion, and a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis, and a motor activation switch within the motor housing portion and adjacent the motor. The reciprocating saw also includes a transmission is positioned downstream of the motor and has a sawbar connectable to a saw blade. The transmission converts a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.

A reciprocating cutting tool is provided, wherein the tool has a reciprocating saw mode and a jig saw mode. The tool includes a reciprocating mechanism; an actuating mechanism and a cutter-lifting mechanism. The reciprocating mechanism includes a reciprocating rod and the cutter-lifting mechanism includes an actuating member and a pushing member. The actuating member includes a first engaging portion and a second engaging portion when the reciprocating rod is driven to perform a reciprocating motion , the reciprocating rod drives the pushing member to deflect close to the first engaging portion or second engaging portion; when the first engaging portion or the second engaging portion is driven to move close to the pushing member, the first engaging portion or second engaging portion pushes the pushing member towards the side which the first engaging portion or the second engaging portion deflects to force the reciprocating rod to implement a cutter-lifting motion.

A power tool includes a prime mover, an output shaft that extends along a first direction and retains a tip tool and is driven by the prime mover, a support member that supports the output shaft to be drivable, a gear that rotates around an axis extending in a second direction crossing the first direction and transmits a power of the prime mover to the output shaft, and a gear cover that accommodates the gear and the support member. Inside the gear cover, a lubricant retention portion capable of retaining a lubricant is arranged at a side of the support member, and the lubricant retention portion is partitioned from a gear accommodation portion that accommodates a gear by a wall extending in a direction intersecting an extending direction of the output shaft in the gear cover.

A guide dresser for cutting or machining a saw guide includes a carriage assembly on which the saw guide is mounted. The carriage assembly includes a faceplate and a retaining plate for engaging opposed surfaces of the saw guide. A rod extends from the faceplate through the saw guide and the retaining plate, with at least a portion of the rod being threaded. A load cell is placed against the retaining plate and a nut is threaded along the rod until the saw guide is clamped against the faceplate. The load cell is able to convert the force exerted by the nut against the load cell into an electrical signal. The electrical signal is transmitted to a computer, which is able to determine a measurement of the torque exerted by the nut.
