Abstract: A hand-held connector milling machine for producing a recess in a workpiece, the recess having a connector hole for receiving at least part of a connector. The connector milling machine includes: an electrical positioning device which is designed to move the milling tool along at least two positioning degrees of freedom, that are in particular linear, relative to the bearing structure; and an electronic control unit which is designed to control the electrical positioning device according to movement information so that the electrical positioning device displaces the milling tool in a movement sequence defined by the movement information along the at least two positioning degrees of freedom, while the milling tool performs a rotational removal movement in order to produce the recess which has the connector hole and a predefined recess geometry.

Abstract: A hand-held milling device for producing a recess in a workpiece that has a bearing means having a bearing structure, which includes a first structure portion and a second structure portion for simultaneously bearing against the workpiece in a stationary manner during the production of the recess, the first structure portion defining a first bearing plane and the second structure portion defining a second bearing plane, and the second structure portion being pivotably mounted relative to the first structure portion. The milling device includes: an electrical positioning device which is designed to displace the milling tool along at least two positioning degrees of freedom relative to the bearing structure; and an electronic control unit which is designed to control the electrical positioning device according to movement information so that the electrical positioning device displaces the milling tool in a movement sequence along the at least two positioning degrees of freedom.

Abstract: An attachment for a hand-held power tool, wherein the attachment has an attachment housing and a drive element on a drive side, which drive element can be coupled to a machine output element of the hand-held power tool in order to drive the attachment and is firmly connected to an output element of the attachment or is motion-coupled via a gear to drive a working tool, wherein the attachment has a fastening device on the drive side for detachable fastening to the hand-held power tool, wherein the fastening device has at least one support surface that is stationary with respect to the attachment housing for providing support on the hand-held power tool in the direction of a support axis and at least one locking body adjustable between a locking position and an unlocking position and loaded into the locking position by a spring assembly.

Abstract: A handle device for releasable fastening on a hand-held power tool (10), wherein the handle device has a clamping ring (41) with a clamping mount (42) for receiving a fastening portion (20) of the hand-held power tool (10) and also has a handle (60), which projects from the clamping ring (41), wherein a clamping-actuation grip (78), which can be activated manually by the operator (BE), can be used to adjust the clamping mount (42) between a clamping position (K), and a release position (L), and wherein the handle device has an axial-form-fitting body (80), which is mounted in a movable manner in relation to the clamping mount (42) and has an axial-form-fitting contour (81) for engagement in a mating axial-form-fitting contour (25) of the fastening portion of the hand-held power tool.

Abstract: A sawing apparatus can have a drive shaft that is rotatable about a central axis for rotationally driving a saw blade. The apparatus includes an electrical rotary feedthrough for the electrically conductive connection of the drive shaft to a connection assembly. The electrical rotary feedthrough includes a first component having a contact section that tapers in the direction of a second component and the shell surface of said contact section forms a first contact surface. The second component has a receiving channel that extends along the central axis and the side surface of the receiving channel forms a second contact surface. The first contact surface lies against the second contact surface in sections. The receiving channel and the tapering contact section has a clearance for ruling out a purely axial abutment of the components. In addition, an electrical rotary feedthrough for a sawing apparatus, is described.
