Milwaukee’s new M12 dust extractor, aka the HammerVac, attaches to your SDS rotary hammer or hammer drill to provide HEPA-quality dust extraction and filtration. This universal adapter won’t replace large-capacity vacuums (like the newly released Makita Xtract Vac), but it does provide convenient containment for small jobs.
When drilling into brick, block, or concrete, airborne dust poses a personal health hazard and environmental contamination concern. That’s why so many brands have been focusing on masonry dust extraction systems and attachments recently.
The beauty of this universal attachment is that it can be attached to any make or model SDS Plus rotary hammer or hammer drill. It connects to your drill or hammer via a side handle collar, with three sizes available to ensure a proper fit.
A 3-position switch allows for on/off/auto power settings.
The HammerVac is available as a kit (2306-22) for about $200 and bare-tool (2306-20) for about $150.

I had a chance to preview the HammerVac at Milwaukee’s 2012 media event, and at the time the dust extractor seemed like a great idea. It still seems like a great idea, but I still have a few reservations.
The HammerVac weighs 3.3 lbs, which is nearly as much as their new M12 rotary hammer. An adapter plus vacuum hose might be easier to deal with when drilling many holes.
What I do like is how the dust extractor attaches to the side of rotary hammers and hammer drills, rather than the bottom as with other brands’ proprietary accessories.
While I am slightly concerned about how often the HammerVac needs to be emptied, Milwaukee engineers assured me that the collection chamber can hold quite a bit of dust before it needs attention.
Masonry dust is nasty stuff to clean up, and you don’t want to breathe it in. A self-contained dust extraction system – especially a universal one that works with other brands’ tools – is a great idea, and I am optimistic that it performs well.
The weight and dust-holding capacity might be an issue for larger jobs, so users will probably want to switch to a full-size vac for heavier usage.
