ABSTRACT:
An angle grinder with a reversible drive mechanism includes a hollow arbour with a bottom flange and a polygonal coupling piece which is keyed into a corresponding polygonal recess in the bottom of the arbour. A retaining bolt extends through the arbour and is threaded into the coupling piece. The coupling piece both couples the arbour and the retaining bolt for simultaneous rotation and retains the disk tool against the flange of the arbour. The retaining bolt is accessible by means of a slide which engages crenelations in the rim of the arbour to lock the arbour against rotation when accessing the retaining bolt.
