A rotatably driveable work tool ( 1 ) of a motor-driven work apparatus has, at a front end ( 2, 3 ), an end plate ( 5, 6 ) lying perpendicularly to a rotational axis ( 4 ). The end plate ( 5, 6 ) has an outer diameter (D<SUB>R</SUB>) which is less than a flight circular diameter (D<SUB>F</SUB>) of the work tool ( 1 ). The end plate ( 5, 6 ) is configured as a roll-up protective ring ( 8 ) which extends in a radial direction ( 14 ) from an inner diameter (D<SUB>I</SUB>) to the outer diameter (D<SUB>R</SUB>). The roll-up protective ring has an axially-extending component from the work tool ( 1 ) outwardly.
