With the Bosch gde 18V-12 dust extractor, you can drill cleanly and safely using your Bosch gbh 18V-22 rotary hammer. The integrated hepa filter captures airborne drilling dust directly at the source, protecting your lungs and keeping the work area clean. Its lightweight, compact design makes overhead drilling into ceilings and walls effortless, without dragging around bulky external vacuum hoses. The extraction system starts automatically when you drill and continues running briefly after you release the trigger to capture any remaining debris. Built for drill bit diameters from 6 mm to 12 mm and drilling depths up to 100 mm.
