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-held power tool, in particular to a screwing device, includes a control device for controlling and/or regulating the tool movement of a tool holder and/or of a tool. The hand-held power tool has an interface for communicating with an external adjustment device. The interface is configured to be connected to the control device in such a way that signals may be transmitted for the parameterization of at least one tool movement sequence. The tool movement sequence includes a plurality of sequentially-progressing tool movements. A method for parameterizing at least one tool movement sequence of a hand-held power tool includes parameterizing the at least one tool movement sequence with a separate setting device in a remote-controlled manner via an interface of the hand-held power.
