A drilling tool includes a motor, a tool holder, a main housing, an elongate grip part, a hollow connection part and a detection device. The motor includes a motor shaft rotatable around a first axis. The tool holder is configured to be rotationally driven around a second axis extending parallel to the first axis and defining a front-rear direction. The grip part is behind the main housing and extends in a direction crossing the second axis. The grip part includes a first end portion located on the second axis and a second end portion spaced apart from the second axis. The connection part connects the second end portion and the main housing. The connection part and the grip part together form an annular part. The detection device is disposed in the connection part and configured to detect a rotation state of the main housing around the second axis.

A power tool includes a motor, a driving mechanism, a main housing, a handle housing, a first guide part and a second guide part. The handle housing is movable relative to the main housing at least in a front-rear direction. The first and second guide parts are configured to guide relative sliding between the main housing and the handle housing in the front-rear direction. Each of the first guide part and the second guide part includes a first engagement part and a second engagement part engaged with each other to be slidable in the front-rear direction. The main housing has the first engagement part. The handle housing has the second engagement part. The second guide part is spaced apart from the first guide part and located rearward of the first guide part in the front-rear direction.

A programmable power tool and method and systems of programming a power tool using wireless communication. An external device having a processor and a transceiver establishes a communication link with the power tool. The external device receives, with the transceiver, a first mode profile stored on the power tool. The first mode profile is defined by a profile type and a first value associated with a parameter for executing the profile type. The external device displays a control screen including the profile type and the parameter at the first value, and receives a user input. The external device generates, in response to the user input, a second mode profile by modifying the parameter to be at a second value. The external device transmits, with the transceiver, the second mode profile to the power tool.

The present invention provides an electric working machine in which a control board can be disposed without limitations based on a length of a brushless motor in a direction along an axial line. The electric working machine comprises: a brushless motor provided with a rotor and a stator; a motor case and a motor housing in which the brushless motor is stored; a control board which is provided outside of the motor housing in a radial direction of an axial line defined at the center of the rotor, and supports the switching elements; a connection board which is provided in the motor case, and supports the sensors; a through hole provided on the motor case; a through hole provided on the motor housing; and leads and signal lines extending from inside of the motor housing to the outside of the motor housing through the holes.

A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

Provided is an impact tool which can perform control in accordance with working situations. The impact tool converts a torque of a brushless motor into a striking force and applies it to a tip tool. The impact tool includes: a motor control unit which makes detection about whether the tip tool is pressed against an object during the rotation of the brushless motor; and a motor control unit which performs speed increase control for increasing the rotational speed of the brushless motor when a state of pressing the tip tool against the object has been detected continuously for a predetermined time.

A hand-held power tool device comprises an impact tool unit configured to generate a pulse on an insertion tool, and a sensor unit configured to detect at least one of at least one operating parameter, and at least one ambient parameter. The sensor unit includes at least one sensor element configured to detect a spatial position of the impact tool unit.

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 mode and a second mode. The hammer drill further comprises a detent radially movable between a locking position and an unlocking position, and a collar movable between a first rotational position in which the hammer lockout mechanism is in the first mode and a second rotational position in which the hammer lockout mechanism is in the second mode. In the first mode the detent is positioned such that the spindle is moveable relative to the housing. In the second mode the detent is positioned such that the spindle is prevented from moving relative to the housing.
