The M12 HAMMERVAC Universal Dust Extractor is a comprehensive solution for eliminating dust when drilling with any SDS Plus rotary hammer. The onboard universal dust extractor with universal side handle allows users to operate it with any SDS Plus rotary hammer, Milwaukee, or other. The AUTOPULSE filter cleaning mechanism cleans the filter automatically after use to remove debris that could otherwise become lodged. Users will be able to safely drill into common construction materials like concrete, stone, brick and mortar with protection from harmful respirable crystalline silica. The M12 HAMMERVAC Universal Dust Extractor allows the user to drill up to 203 mm (8") in depth and up to 32 mm (1-1/4") in diameter with the two included nozzles, designed for small and large diameters. The adjustable depth stop allows the user to quickly and accurately set the desired hole depths. When the translucent dust box is full, it can be emptied without exposure by hooking it up to a large dust extractor to vacuum out the dust. This M12 Universal Dust Extractor has an Auto On/Off Mode to save the user time and battery life, by automatically activating suction when drilling. The MILWAUKEE M12 HAMMERVAC runs off any Milwaukee M12 REDLITHIUM -ION Battery, to be a fully self-powered, cordless unit for maximum portability.
