ABSTRACT:
Accessory devices for a hand driven tool such as, for example, an angle grinder with the accessory device including an eccentric unit and a resilient coupling for a toolholder whereby an oscillating, elliptical path of movement is imparted to the toolholder in an operating range of the hand driven tool. The eccentric unit and the resilient coupling form one module with the toolholder forming an independent structural assembly thereby enabling the toolholder to be readily exchangeable.
