The MILWAUKEE® HAMMERVAC™ 1-1/4” Dedicated Dust Extractor features an inline design engineered to connect directly to and be powered by the MILWAUKEE® M18 FUEL™ 1-1/4” SDS Plus D-Handle Rotary Hammer w/ ONE-KEY™. Utilizing the same replaceable certified HEPA filter as other HAMMERVACS™, which filters 99.97% of all particles greater than 0.3µm, means more compatibility on the jobsite. The built-in adjustable depth stop and ruler offer easy and precise adjustments. This dust extractor allows full OSHA Table One Compliance when drilling up to 1-1/4” in diameter and 8” in depth. This extractor features MILWAUKEE® AUTOPULSE™ Filter Cleaning Mechanism that automatically cleans the filter after each use, ensuring that users are able to drill more effectively and for longer before needing to empty the dust box. The dust box comes equipped with a vacuum port that allows users to suction out the dust with a large vacuum or dust extractor instead of dumping the dust out into a trash receptacle, ensuring minimal exposure.
