A worktable with a tabletop divided into a workbench panel and a tool mounting panel mounted on a tabletop frame. The tool mounting panel is adapted for the mounting of power tools such as a circular saw, a saber saw or compass saw, and a router or milling machine, and is pivotably attached to the tabletop frame such that it can be swung upwards and positioned at an inclined position above the workbench panel, thereby making it easy to mount and dismount power tools. The worktable has foldable legs which are attached to the tabletop frame only underneath the workbench panel. The legs can be folded underneath the tool mounting panel without obstructing a tool mounting area on the tool mounting panel.

Worktable

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.
