Abstract

See full text

A hand-guided impact hammer and hammer drill having a handgrip which is spring-mounted relative to the hammer housing. At the bottom, the handgrip is spring-mounted harder, with greater stability against lateral displacement relative to the hammer housing, than at the top. On the one hand, during normal operation of the hammer, an optimum vibration damping is provided, and on the other hand, even during great pressure on the handgrip, and during lateral twisting of the handgrip, no direct contact can occur between the parts of the handgrip and the parts of the housing. Furthermore, the hammer can be efficiently guided at all times, even with heavy tools.
