A hand-power tool includes at least one oscillation-damping device that has at least one damping spring, a damping mass, and a mechanism housing. The oscillation-damping device has at least two retaining parts that at least partly enclose the damping mass.

Hand-power tool with an oscillation-damping device

A hand-power tool includes at least one oscillation-damping device that has at least one damping spring and a damping mass. The hand-power tool also includes a drive mechanism and a mechanism housing. The mechanism housing has a housing cover which is provided for closing a chamber in which the drive mechanism lies, and the housing cover has at least one fixing mechanism that at least partially fixes the oscillation-damping device in at least one operating state.

Hand-power tool comprising an oscillation-damping device

The invention is based on a handheld power tool, having at least one vibration-cancelling device that has at least one cancellation spring and one cancellation mass. It is proposed that the cancellation mass is constructed of at least one first mass part and at least one second mass part.

Handheld power tool

The invention relates to a hand-held machine tool, particularly to a drill hammer and/or chisel hammer, having a hand-held machine tool housing and a transmission chamber with at least one transmission element arranged inside the hand-held machine tool housing. According to the invention, the hand-held machine tool includes a pressure equalization unit, provided for equalizing pressure in the transmission housing and serving at least partially for supporting the transmission element.
