The Milwaukee M18 FUEL Overhead Rotary Hammer w/ Integrated Dust Extraction is a cordless SDS Plus rotary hammer purpose-built for repetitive overhead drilling where dust control and ergonomics matter. Milwaukee describes it as a 2-in-1 design with a built-in dust extractor, HEPA filtration, AUTOPULSE filter cleaning, and an overhead-focused handle layout intended to reduce fatigue during ceiling anchor work. ONE-KEY compatibility, AUTOSTOP kickback control, and a compact dust-compliant setup position it as a specialty concrete tool rather than a general rotary hammer. This 3311-20 entry is the bare-tool configuration for users who already own M18 batteries.
