Abstract: A cut-off wheel for machine tools, in particular for handheld power grinders, has a blade body (8), on the outer edge of which at least two cutting segments (9) are mounted. Seen in the circumferential direction, the outer edge of the blade body is subdivided into identical segment receiving portions (10), each of which is assigned a cutting segment.

Abstract: The invention describes a cutting disc (100) comprising a circular-disc-shaped body (10) with a central hole (11) for accommodating a drive spindle, an annular cutting region (13), containing abrasive, at the circumference (12) of the circular-disc-shaped body (10) and a centred plastic damping element (20) with a central hole (21), wherein the damping element (20) is arranged on at least one first flat side (15) of the circular-disc-shaped body (10).

Abstract: A slaving and blocking device for transmitting a torque from a driving part to a driven part and for stopping the driven part at a torque engaging the driven part has a slaving element fixable on the driving part and having slaving claws offset from one another in a circumferential direction, a roller star wheel connectable to the driven part and having points of a star offset from one another in the circumferential direction, and a stationary clamping ring located concentrically with the slaving element and the roller star wheel. A contact face on the points of the star is configured so that the clamping rollers, which when the slaving element is driven are pressed by the slaving claws against contact faces of the points of the star, are thrust inwards.
