An extraction connection system for portable machine tools includes at least one tool connection element, at least one suction apparatus connection element, and at last one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

Extraction connection system

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 Mto a nominal power Pis 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 Mto the nominal power Pis at most 0.75 g/W*P+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*P&#x2212;540 g.

Hand-held power tool having an electronically commutated electric motor and an integrated electronics system

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.

Hand power tool

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.

The invention is based on a method for producing a screw connection by means of a cutout screwdriver () 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 () and transmitted to an external monitoring unit (). The invention also discloses a device for executing the method as well as a cutout screwdriver.
