  • Patent number: 9662760
    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.

  • Patent number: 9233457
    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.

  • Publication number: 20030089509
    Abstract: A hand-operated machine tool is disclosed that rotationally drills or percussively chips or both. An embodiment of the hand-operated machine tool includes a toolholder that is used to hold tools having a grooved shank. The toolholder has a toolholder body and at least one radially moving locking member, for example a locking sphere, that is insertable into a groove in the tool and the locking member is radially locked in position by a retaining element that may be displaced by an actuating element to a position that radially releases the locking member. In an embodiment of the invention, the toolholder has at least one sealing device that seals at least one chamber outwardly surrounding the locking member. The sealing device includes at least one sleeve-shaped component that is separate from the actuating element and at least partially defines the volume referred to as the chamber.
