Abstract: A device for introducing openings into a disposal bag for a vacuuming device, wherein the vacuuming device has a suction head and a collecting tank. The includes components that are configured in a manner corresponding to one another, wherein the components of the device that are configured in a manner corresponding to one another include an open structure, wherein the open structure is designed to effect pressure equalization between a first region and a second region of the collecting tank. Within the meaning of the invention, it is preferred for the proposed device to include a punch and a die, wherein the punch is arranged in the suction head and the die is arranged in the collecting tank. In a second aspect, the invention relates to a vacuuming device that includes at least one proposed device. In a further aspect, the invention relates to a method for introducing openings into a disposal bag for a vacuuming device.

Abstract: An apparatus for a vacuum cleaner for compensating air pressure fluctuations includes a main body through which an air flow is flowable in a flow direction, where the main body contains a passage opening, and a separating element, where the passage opening is separated from ambient air by the separating element. The separating element is movable such that, as a result of a movement of the separating element in a radial direction, a reservoir which receives an air volume is produced between the main body and the separating element such that a vacuum produced in the main body by the air flow is at least partially maintained.

Abstract: A drill bit having a chip channel which opens out into an annular gap volume formed by an adapter element is disclosed, along with a drill chuck attachment and a drilling machine.
