[origin: EP0755756A2] The electric hammer drill has an axially displaceable drilling spindle (4) supported by an axial roller bearing (42). The adjustment member (30) acts on the spindle through the bearing and is mounted between the partition wall (6) on the engine side and a drive wheel (18) set on the spindle. The adjustment member interacts directly with the partition and either the adjustment member or partition has an axially extended projection (34) facing the relevant other part which interacts with an indentation (36) in the other part.
