Our 1 in. HAMMERVAC™ Dedicated Dust Extractor (2912-DE) is designed to connect directly to the MILWAUKEE® M18 FUEL™ 1 in. SDS Plus Rotary Hammer Kit (2912-20 and 2914-20). Employing the same replaceable HEPA certified filter as other HAMMERVAC™ models, which filters 99.97% of all particles greater than 0.3 µm, means expanded compatibility on the job site. The built-in adjustable depth stop and ruler provide simple and precise adjustments. The dust extractor ensures full OSHA Table One compliance when drilling holes up to 1 in. in diameter and 6 in. deep. This dust extractor features the AUTOPULSE™ filter cleaning mechanism that cleans the filter after each use, ensuring you drill more effectively and longer before having to empty the dust box. The dust box is equipped with a vacuum port to extract dust with a large wet/dry vacuum or dust extractor (such as the 8960-20) rather than dumping dust into a trash can, ensuring minimal exposure.
