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.

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.

Control device for a hand-held power tool

A hand power tool has a striking element via which a tool () in a tool holder () can be driven in striking fashion, which the tool holder can be detachably secured&#x2014;via its body ()&#x2014;to a drive part () via at least one locking element (), which the locking element, in its engaged position, is capable of being fixed in position radially by a retaining element (), which the retaining element is capable of being automatically guided by means of an operating element () out of its locked position into a release position that radially releases the locking element () in order to release the tool holder (), whereby the retaining element () is capable of being moved by a corresponding component () into its release position against a spring force of a spring element () when the tool holder () is pushed onto the drive part (), wherein the retaining element () is captively held on the drive part () and is capable of being guided into its release position by the operating element () in the push-on direction () of the tool holder () against a spring force of a spring element ().

Hand machine tool with a removeable tool holder

A hand power tool has a housing (), a hammer barrel (), a tool receptacle () that is separated from the hammer barrel () at least one locking body () for fixing the tool receptacle () in a direction of rotation (), a transmission unit () arranged radially outwardly of the tool receptacle () for transmitting a torque from the tool receptacle () radially outwardly and fixing the tool receptacle () in the direction of rotation () of the tool receptacle () on the housing (), one part of the transmission unit () being formed by an actuating sleeve (), the transmission unit () having a claw ring () which is separate from the actuating sleeve () and the tool receptacle () being connected through the claw ring () with the actuating sleeve () in the direction of rotation ().

Hand machine tool

A tool holder for a power tool, such as a drill hammer, a chisel hammer, and both, includes a striking mechanism for strikingly driving a tool, a base body, a drive part on which the base body is releasably mounted, at least one locking body for releasably mounting the base body on the drive part, a component having a throughgoing passage in which the at least one locking body is arranged, a securing body which radially fixes the at least one locking body in its engaging position, an actuating element for unlocking the securing body from its locking position to an unlocking position for radially reieasing the at least one locking body, and at least one holding element which holds the at least one locking body in the unlocking position of the securing body in the throughgoing passage. The holding element is lowered or lowerable into the component having the throughgoing passage and is overrun by the securing body.

Tool holder

A manual machine tool ( ) with a housing ( ) that carries an adjustable bit stop ( ), particularly on a supplemental handle ( ), becomes more convenient and safer to operate because the bit stop ( ) can be fixed in positive fashion, particularly in latching fashion, next to the manual machine tool ( ).
