摘要： A power tool includes a housing with a motor housing portion and a drive housing portion, a handle extending from the housing and defining a gap between the handle and the housing, a motor located within the motor housing portion having a motor output shaft, a fan coupled to the motor output shaft, a battery to provide power to the motor, a trigger coupled to the handle and manipulable to energize the motor, a spindle extending within the drive housing portion and driven by the motor output shaft to rotate about an axis, and a fluid delivery system configured to supply a fluid to the spindle. The housing includes an air intake opening and a deflector to inhibit the fluid from entering the housing through the air intake opening, and rotation of the fan draws an airflow into the housing through the air intake opening.

摘要： A power tool includes a housing, a motor, a spindle, a handle holder and an auxiliary handle. The housing includes a motor housing portion, a drive housing, and a mounting portion between the motor housing portion and the drive housing. The motor is located within the motor housing portion. The spindle is configured to rotate about a rotational axis in response to torque received from the motor. The handle holder is coupled to the drive housing and defines a first mounting point, and the mounting portion defines a second mounting point. The auxiliary handle is selectively attachable to each of the first and second mounting points, and the first mounting point is located at a first position along the rotational axis, and the second mounting point is located at a second position offset from the first position in a direction along the rotational axis.

摘要： A rotary power tool comprises a drive mechanism, a spindle rotatable about a rotational axis in response to receiving torque from the drive mechanism, and a first shank coupled for co-rotation with the spindle and having a first diameter. The first shank includes a first threaded portion upon which a first tool bit is receivable. A second shank is coupled for co-rotation with the spindle and extends outwardly from and coaxial with the first shank. The second shank has a second diameter that is smaller than the first diameter and a second threaded portion upon which a second tool bit is receivable.

摘要： A power tool includes a housing, a motor supported within the housing, a handle extending from the housing, a trigger, a spindle, and a fluid delivery system. The handle defines a gap between the handle and the housing, and the trigger, coupled to the housing, is manipulable to energize the motor. The spindle is configured to rotate about a rotation axis in response to torque received from the motor, and the fluid delivery system is configured to supply fluid to the spindle. The fluid delivery system includes a valve operable to regulate a flow of fluid to the spindle, and the valve includes an actuator disposed within the gap.

摘要： A cut-off saw including a housing, a support arm coupled to and extending from the housing in a first direction, a cutting wheel supported by the support arm, a rear handle extending from the housing in an opposite, second direction, a motor disposed in the housing, a battery pack configured to power the motor, and a battery receptacle defined by the housing in which the battery pack is receivable. The battery pack is positioned between the cutting wheel and the rear handle. The cut-off saw also includes a battery cover coupled to the housing. The battery cover is selectively moveable between a closed position, in which the battery pack is enclosed by the battery receptacle and the cover, and an open position, in which the battery pack is accessible.

摘要： An impact power tool includes a motor, an output shaft to which a tool bit is attachable for performing work on a workpiece, and an impact mechanism disposed between the motor and the output shaft for converting a continuous torque output from the motor to discrete pulses of torque upon the output shaft, the impact mechanism including a cylinder assembly, a cavity defined within the cylinder assembly containing a hydraulic fluid, and a collapsible member having a first end and a second end opposite the first end. The collapsible member is maintained in a shape coinciding with that of the cavity by fitment within the cavity, with the first and second ends being disconnected from each other. The collapsible member is collapsible to compensate for thermal expansion of the hydraulic fluid during operation of the impact mechanism.

摘要： An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.

摘要： A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis. A cam surface is formed on one of the input member or the output member. First and second compression springs are carried by the other of the input member or the output member for co-rotation therewith. A follower has a circular cross-sectional shape and is biased against the cam surface by the first and second compression springs. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with each of the first and second compression springs. The line of action does not intersect the rotational axis.

摘要： A clutch mechanism, for use in a rotary power tool having a motor, comprises an input member to which torque from the motor is transferred and an output member co-rotatable with the input member, the output member defining a rotational axis. The clutch mechanism further comprises a cam surface formed on one of the input member or the output member and a compression spring carried by the other of the input member or the output member for co-rotation therewith. The clutch mechanism also comprises a follower having a circular cross-sectional shape biased against the cam surface by the compression spring. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with the spring. The line of action does not intersect the rotational axis.
