A work bench includes a frame formed of interconnected longitudinal and transverse section beams defining a frame plane; and a vise formed of a stationary vise jaw and a movable vise jaw movable towards and away from the stationary vise jaw generally in a direction parallel to the transverse beams. The movable vise jaw is displaceably supported on the transverse beams by a spindle-and-guide arrangement. Each transverse beam has an open side oriented in a direction parallel to the frame plane and a leg part extending in the length dimension of the transverse beam and having wall faces arranged parallel to the frame plane. A guide member is affixed to the movable vise jaw adjacent each transverse beam. The guide member, which has a part traversed by the spindle, is provided with a groove-like recess extending in the length dimension of the respective transverse beam. The leg of the respective transverse beam extends into the groove-like recess in the respective transverse beam.

A hammer drill has a motor-actuated drive piston and a free percussion body accommodated in a common, stationary cylinder. The percussion body is caused to move back and forth by the drive piston with air as the coupling and buffer medium. The hammer drill further has a tool holder driven by a hollow drive shaft which encloses the stationary cylinder and is driven by a motor which also actuates the drive piston.
