Abstract

The drilling hammer has a percussion and rotary drive disposed in a housing. A drill sleeve (14) is disposed in the housing and cooperates with the percussion and rotary drive, and with a tool or chuck for receiving the tool. A spring (32) connected to an outer periphery of the drill sleeve has an elastomeric material (34) with a wall thickness of 1-10 millimeter. A damping mass is held by the spring for deflection of the damping mass relative to the drill sleeve in a peripheral and longitudinal direction of the drill sleeve due to an elasticity of the spring.
