Abstract: A hand-held power tool, in particular an angle grinder, having a drive unit, has an electronically commutated electric motor and has an electronics system which is integrated in an appliance housing. The ratio of a weight of the hand-held power tool MHWZM to a nominal power PN is selected in such a way that, in a power range of from 0 to 1200 W, the ratio of the weight of the hand-held power tool MHWXM to the nominal power PN is at most 0.75 g/W*PN+1200 g, and, at a value of the nominal power of greater than 1200 W, the ratio of the weight of the hand-held power tool to the nominal power is at most 2.2*PN?540 g.

Abstract: A hand power tool includes a drive unit, an electronic unit, and a cooling device configured to cool at least one of the drive unit and the electronic unit. The hand power tool also includes at least one of an open-loop control unit and a closed-loop control unit configured to control the cooling device.

Abstract: A hand power tool, in particular an angle grinder, includes a drive unit and an electronic unit. The hand power tool further includes an after-run cooling unit configured, at least partially, to cool the drive unit and/or the electronic unit substantially after an operating state of at least the drive unit.

Abstract: A hand-held power tool comprises an electromotive drive that is configured to drive an output shaft and that is positioned in a first housing part, wherein the electromotive drive and the output shaft define a common first axis. The hand-held power tool further comprises an electronic system that is configured to energize the electromotive drive and that is positioned in a second housing part. The second housing part is elongated and includes a grip that is distal from the electromotive drive. The second housing part defines a second axis that is at an angle to the first axis between 60° and 120°.

Abstract: A hand power tool, in particular an angle grinder, includes a drive unit, an electronic unit, and a cooling device configured, at least partially, to cool the drive unit and/or the electronic unit. The cooling device includes at least one cooling unit configured, at least partially, for localized cooling.

Abstract: A hand power tool device includes a drive unit, an electronic unit, and a suction unit configured to extract dust out of a working region by suction. The hand power tool device further includes a cooling unit configured, at least partially, to cool the drive unit and/or the electronic unit. The cooling unit and the suction unit are configured, at least partially, as a single piece.

Abstract: The invention is based on a method for producing a screw connection by means of a cutout screwdriver (10) that terminates a screw driving operation when a predetermined torque is achieved. According to the invention, data relating to an operation are detected in the cutout screwdriver (10) and transmitted to an external monitoring unit (20). The invention also discloses a device for executing the method as well as a cutout screwdriver.

Abstract: The invention relates to a power tool having a machine housing and a ventilation unit which is provided for cooling a motor unit and/or an electronics unit encased by the machine housing, the cooling being accomplished by means of suctioning a cooling air flow, and which has a deflection unit. The invention provides that the deflection unit has at least one deflection channel that is provided for separating contaminant particles and air of the cooling air flow by means of a deflecting of the cooling air flow.
