Sawing device and electrical rotary feed-through for tool, in particular for sawing device

The invention describes a sawing device (10) having a drive shaft (12) rotatable about a central axis (A) for rotationally driving a saw blade (14). The sawing device (10) comprises an electrical rotary feed-through (26) for an electrically conductive connection of the drive shaft (12) to the connection assembly (28). The electrical rotary feed-through (26) comprises a contact portion having a tapering in the direction of the second component, and a housing surface of the contact portion forms a first contact surface. The second part has a receiving channel extending along a central axis (A) and a side surface of the receiving channel forms a second contact surface. The first contact surface at least partially abuts the second contact surface. In addition, the receiving channel and/or the tapered contact portion includes a gap that disables the first component from fully axially abutting the second component. The invention further relates to an electrical rotary feed-through (26) for a tool, in particular for
