ABSTRACT:
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 (DR) which is less than a flight circular diameter (DF) 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 (DI) to the outer diameter (DR). The roll-up protective ring has an axially-extending component from the work tool (1) outwardly.
