Abstract
A disc grinder includes a grinding wheel cover rotatably mounted to a gear housing about an axis of a spindle. A stopper device can restrict a position adjustable range of the grinding wheel cover of the spindle and includes a first stopper on the side of the grinding wheel cover and a second stopper on the side of the gear housing. The first stopper and the second stopper have stopper surfaces for contacting with each other. An impact absorbing device can absorb an impact produced when the stopper surfaces contact with each other.
