A handheld power tool, including a tool socket on a drive shaft for purposes of holding a tool, the drive shaft executing a rotating and partially tangentially striking movement using a tangential striking mechanism drivable by a drive. The tangential striking mechanism has an anvil associated with the drive shaft and a hammer associated with the drive, movable with respect to each other so as to strike each other axially when under the effect of the force of at least one first spring, and to strike each other tangentially when the anvil and the hammer are rotated. The hammer has a main mass, and an extra mass that is under the effect of a second spring couplable to the main mass.
