Abstract
In a vacuum drill dust extractor having a pot-shaped housing through which a rotatably drivable drill can be passed axially, and having a piston unit which is arranged axially displaceably in the housing, cooperates with a drill-side stop, contains an induced draft blower device and can be set against an associated stop on the housing side by means of a spring over which it engages, a high degree of reliability and operational safety are achieved in that at least one induced draft blower provided with its own drive motor and an energy storage unit provided with a charging socket and associated with each motor driving an associated induced draft blower are provided in the piston unit.
