An apparatus includes a spindle, a pecking mechanism, and a clutch mechanism coupled to the pecking mechanism. The spindle includes a drill tool and the spindle is configured to be fed in a first direction during a drilling operation. The pecking mechanism is configured to retract the drill periodically during the drilling operation. The clutch mechanism is configured to selectively engage the pecking mechanism during a portion of the drilling operation. The clutch mechanism is configured to constrain the rotation of the washer such that the spindle drill is retracted a predefined distance periodically.

A power tool communication system including an external device including a first controller configured to transmit, via wireless communication to a power tool, configuration data including a work light duration parameter value and a work light brightness parameter value. The power tool includes a housing, a brushless direct current (DC) motor, a trigger, a work light, a wireless communication circuit configured to wirelessly communicate with the external device to receive the configuration data, and a second controller configured to control a work light duration of the work light based on the work light duration parameter value, and control a work light brightness of the work light based on the work light brightness parameter value.

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.

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.

An electric power tool includes a motor, an output shaft, a drive force transmission configured to reduce drive speed of the motor and transmit drive force of the motor to the output shaft; a trigger that can be pulled by a user; a rotation speed changing circuitry configured to change a rotation speed of the output shaft that corresponds to a maximum pulled amount of the trigger to a limited rotation speed that is lower than a maximum rotation speed of the output shaft in a non-limited rotation speed mode; and a rotation speed control circuitry configured to control a rotation speed of the motor in correspondence with a pulled amount of the trigger to obtain the rotation speed of the output shaft that is changed by the rotation speed changing circuitry.

The present disclosure is directed to a self-propelling surgical device and method for using the same. The device is configured to drill a hole into an object, such as a bone, and subsequently insert an implant, such as a screw or pin, into the hole. The device drills the hole and inserts the implant under its own power. The device may perform desired actions automatically or manually.

An adapter for a power tool including a housing, a tool-side connector, and a battery-side connector in electrical communication with each other. The tool-side connector is configured to couple to a power tool, and the battery-side connector is configured to couple to a battery pack. The adapter also includes a communication interface configured to couple with an external device, and a controller. The controller is configured to determine a state of the power tool, operate in a data transmission mode when the power tool is in the idle state, operate in a pass-through mode when the power tool is in the active state, and switch between the data transmission mode and the pass-through mode based on the state of the power tool.

A covering member made of a resin is integrally molded with a sensor substrate of a brushless motor in a circular saw by low-temperature, low-pressure injection molding. The covering member covers rotation detecting elements, a thermistor, resistors, and connecting portions (terminals) of lead wires that serve as electrically conductive portions conducting electric currents.

A tool with a transmission having a reduction gearset and a speed selector. The speed selector has a member, an actuator and a shifter assembly. The member is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator includes a pivoting yoke and a follower that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly has a selector switch, a switch fork, and a pair of springs. The selector switch is slidable between a first switch position and a second switch position. The shift fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the shift fork relative to the selector switch into a neutral position.
