spring 10 as far as the stop 12 an initial tension upon the fastening nut 14 is thereby generated as the abrasive disk 1 is being appropriately mounted in this case the disk spring 10 can have in particular a characteristic in which the force f initially increases and subsequently decreases it can thereby be achieved that the frictional contact between the fastening nut 14 and the tool spindle 3 initially increases upon a first slackening of the fastening nut 14 for example in the case of a braking operation such that further slackening of the fastening nut 14 is counteracted the presence of the stop 12 ensures that the operator when fixing the abrasive disk 1 on the tool spindle 3 obtains a defined tactile indication of the point at which the abrasive disk 1 is sufficiently fixed on the tool spindle 3 even in those cases in which the operator fails to tighten the fastening nut 14 until it reaches the stop 12 the electric hand power tool appliance when first switched on or energized will automatically tighten the fastening nut 14 until it reaches the stop 12 because of the moment of inertia of experienced by the abrasive disk 1 and will thereby fix or otherwise effectively secure the abrasive disk 1 on the tool spindle 3 in a practically and appropriate captive manner in an embodiment of the invention that is not represented in the drawing the.
