A drilling tool includes: a drive source; a bit attachment portion to which an end bit is attachable; a power transmission portion configured to apply a motive force to the end bit attached to the bit attachment portion; an operation portion switchable between an ON-state and an OFF-state by a manual operation and configured to receive a setting operation for setting a stop condition; and a controller configured to set the stop condition based on the setting operation, and to start driving of the drive source in response to a first switching operation for switching the operation portion from the OFF-state to the ON-state. In a state where the stop condition is set, even when the operation portion is in the ON-state, the controller stops driving of the drive source in response to the stop condition being met while the drive source is being driven.

A power tool having a rotary hammer mechanism has a first motor; a driving mechanism configured to operate by power of the first motor in an action mode selected from a plurality of action modes including a first mode of at least rotationally driving a tool accessory and a second mode of only linearly driving the accessory; a tool holder configured to be rotationally driven by torque transmitted from the first motor; a second motor; a clutch member configured to transmit torque to the holder in a transmitting position and to interrupt the transmission in an interrupting position; and a transmitting mechanism configured to convert rotation of the second motor into linear motion and transmit the linear motion to the clutch member. When the tool body excessively rotates around the driving axis, the second motor moves the clutch member from the transmitting position via transmitting mechanism to interrupt the transmission.

A power tool having a rotary hammer mechanism has a motor, a driving mechanism, a tool body that houses the motor and the driving mechanism, a handle having a grip part, and a first operation member. The driving mechanism is configured to operate by power of the motor in an action mode that is selected from a plurality of operation modes including a first mode of at least rotationally driving a tool accessory around a driving axis and a second mode of only linearly driving the tool accessory along the driving axis. The grip part extends in a direction crossing the driving axis and is configured to be held by a user. The first operation member is on the tool body and faces the grip part. The first operation member is configured to be manually operated by the user to change the action mode of the driving mechanism.

A docking station for a dust collection box comprising: a housing; a socket formed by the housing configured to receive a dust collection box of a dust extractor; first and second apertures formed through a wall of the housing which aligns with air outlet and inlet apertures of a dust collection box when the dust collection box is mounted within the socket; a connector connectable to a vacuum source; and a dust channel mounted inside of the housing, which provides a passageway between the second aperture and the connector. The docking station may further include an air vent formed through a wall of the housing to allow air surrounding the housing to enter a cavity formed inside of the housing, where the first aperture is connected to the cavity in the housing to allow air in the cavity to exit the housing through the first aperture.

A hammer drill comprises a drive mechanism including a spindle, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, and a hammer lockout mechanism adjustable between a first mode and a second mode. The hammer drill further comprises a clutch adjustable between a first state and a second state. The hammer drill further comprises a collar rotatably coupled to the housing and movable between a first rotational position in which the hammer lockout mechanism is in the first mode and the clutch is in the first state, a second rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the first state, and a third rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the second state.

A power tool allows mode switching and clutch operation torque switching using a single ring. An electric vibration driver drill includes an internal gear that meshes with planetary gears, an internal gear lock pin that moves forward relative to the internal gear to lock the internal gear, a first vibration cam fixed to a spindle, a second vibration cam that rubs against the first vibration cam and rotate relative to a gear housing, a vibration switch lever that moves forward relative to the second vibration cam to lock the second vibration cam in a nonrotatable manner, and an annular change ring that switches between forward movement and rearward movement of the internal gear lock pins and switches between forward movement and rearward movement of the vibration switch lever.

A rotary hammer is adapted to impart axial impacts to a tool bit. The rotary hammer comprises a housing, a motor supported by the housing, a gearcase, and a spindle housed in the gearcase and coupled to the motor for receiving torque from the motor, causing the spindle to rotate. The rotary hammer also comprises a reciprocating impact mechanism operable to create a variable pressure air spring within the spindle. The rotary hammer also comprises a vibration damping mechanism including a base on the gearcase, a counterweight circumscribing the base, and a first spring arranged between the base and the counterweight and defining a first biasing axis that is parallel to the reciprocation axis. The vibration damping mechanism also includes a second spring arranged between the base and the counterweight and arranged along the first biasing axis.

A hand-held impact tool includes a motor, a driving mechanism, a tool body, a main handle, a first detection part, a second detection part and a control part. The tool body is configured such that an auxiliary handle is removably attached thereto. The main handle is connected to the tool body. The first detection part is configured to detect selected one of a plurality of modes. The second detection part is configured to detect whether or not the auxiliary handle is attached to the tool body. The control part is configured to control operation of the impact tool based on detection results of the first detection part and the second detection part.

A power tool has a motor, a rotary shaft and a housing. The rotary shaft has a first end portion on a first direction side and a second end portion on a second direction side in an axial direction of the rotary shaft. The housing is configured to store a lubricant on the first direction side of the first end portion of the rotary shaft. The rotary shaft has a first hole and a second hole. The first hole extends in the axial direction and that has a first opening in the first end portion of the rotary shaft. The second hole extends in a direction crossing an axis of the rotary shaft, that communicates with the first hole. The second hole has a second opening in an outer peripheral surface of the rotary shaft. A spiral part is provided within the first hole.

An electric working machine in one aspect of the present disclosure includes an output shaft, a motor, a housing, an acceleration detector, a twisted motion detector, a reference level changer, and a motor controller. The acceleration detector detects an acceleration of the housing in a circumferential direction of the output shaft. The twisted motion detector detects a twisted motion of the housing based on a reference level and the acceleration detected. The reference level determines that the housing is twisted. The reference level changer changes the reference level based on a rotating motion of the output shaft.
