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.

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: An attachment (110) for a hand-held power tool (200), in particular a screwdriver or drill, wherein the attachment (110) has an attachment housing (113) and a drive element (123) on a drive side (111), which drive element can be coupled to a machine output element (221) of the hand-held power tool (200) in order to drive the attachment (110) and is firmly connected to an output element (120A) of the attachment (110) or is motion-coupled via a gear (530) in order to drive a working tool (242), wherein the attachment (110) has a fastening device (105) on the drive side (111) for detachable fastening to the hand-held power tool (200), wherein the fastening device (105) has at least one support surface (232) that is stationary with respect to the attachment housing (113) for providing support on the hand-held power tool (200) in the direction of a support axis (ST) and at least one locking body (150) adjustable between a locking position and an unlocking position and loaded into the locking position by a spring a
