A hammer drill includes a housing, a first ratchet fixed to the housing, a spindle rotatably supported by the housing about an axis, and a second ratchet coupled for co-rotation with the spindle. The second ratchet is engageable with the first ratchet in response to rearward displacement of the spindle to impart a hammering action on the spindle. The hammer drill further includes a thrust bearing having an arm extending away from the axis, and a selector ring having a post extending toward the arm. The selector ring is rotatable between a first position in which the post is engageable with the arm to limit the rearward displacement of the spindle and prevent engagement of the first and second ratchets, and a second position in which the post is misaligned with the arm to permit the rearward displacement of the spindle and engagement of the first and second ratchets.

A power tool including a brushless motor having a sensor circuit board has higher durability. The power tool includes a housing, a brushless motor including a rotor having a rotational shaft, a stator, and a sensor circuit board fixed to the stator and having a rotation detecting element that detects rotation of the rotor, and receiving the rotational shaft through the sensor circuit board, and a bearing held in the housing and supporting the rotational shaft. The bearing is located to overlap the rotation detecting element in an axial direction of the rotational shaft.

A power tool contains a brushless motor that includes a stator having a stack thickness and an outer diameter, a rotor having a diameter, and a motor shaft extending from the rotor and having a rotational axis. A drive mechanism is operably coupled to the motor shaft and is configured to drive a tool accessory in relation to a drive axis. A first housing houses the motor and the drive mechanism. The drive axis does not intersect the brushless motor, but the rotational axis of the motor shaft intersects the drive axis. The outer diameter of the stator is at least five times greater than the stack thickness. Furthermore, the diameter of the rotor is greater than the stack thickness.

A setting tool is used for a setting tool system for setting capsule anchors, wherein the setting tool includes a shank and a head arranged at one end of the shank having a connecting section to which a drive head of a capsule anchor may be connected, wherein the shank includes in a threaded section which is adjacent to the head, a thread, and a thread-free section at an end of the shank opposite the head. Further, a set is used for a setting tool system for setting capsule anchors, including an adapter, which may be coupled to a drive machine, and at least one setting tool. Additionally, a setting tool system includes a setting tool or a set for a setting tool system and a capsule anchor and/or a drive machine.

A control method of an impact wrench for setting an expansion anchor carries out a first sequence in response to a button being pressed. In a first phase, a rotary impact is repeatedly exerted on a screw element of the expansion anchor and a torque transmitted from the rotary impact to the screw head is estimated. The first phase S1 is continued until the estimated transmitted torque exceeds a threshold value specified for the expansion anchor. In a second phase, a number of rotary impacts specified for the expansion anchor are exerted on the screw head. If the button is released before the end of the first sequence, a premature release of the button and the phase in which the button was released is stored in a memory. In response to the button being pressed when a premature release is stored in the memory, a second sequence is carried which depends on the phase in which the button was previously released.

A power tool device, in particular a portable power tool, includes at least one signal switching unit that has at least one signal switching element that is actuable at least in order to activate a drive unit of the power tool. The power tool device further includes at least one operating mode selection unit that has at least one operating mode selection element that is actuable in order to select an operating mode of the drive unit, and at least one locking unit that has at least one locking actuating element at least for locking the signal switching element. The power tool device also includes at least one electronic unit that is configured to control and/or regulate the drive unit at least depending on an evaluation of a setting parameter of the locking actuating element.

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 dust collecting system includes a power tool and a stationary dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The stationary dust collector is configured to be placed separately from the power tool and to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a control device configured to control a rotation speed of the second motor according to a driving state of the power tool.

A dust collecting system includes a power tool and a dust collector. The power tool includes at least one battery-mounting part, a first motor, a driving mechanism and a body housing. The at least one battery-mounting part is each configured to removably receive a battery. The first motor is configured to operate with electric power supplied from the battery. The driving mechanism is configured to drive the tool accessory by power of the first motor. The body housing houses the first motor and the driving mechanism.
