The Dust Extractor Attachment with HEPA Filter (model DX09) is for use with the 18V LXT Lithium-Ion Cordless Brushless 1 in. Rotary Hammer (XRH011, sold separately). The DX09 Dust Collection Vacuum Attachment features a HEPA filter engineered to capture 99.97% of dust particles (size 0.3 microns and larger) for improved dust collection. The Dust Extractor Attachment is powered by a separate motor allowing the rotary hammer to consistently maintain peak drilling performance. The high-capacity dust container is transparent and provides an accurate level indicator of collected material. The container captures concrete dust during drilling, activated by the tool and provides a 3-second delay to help capture remaining dust. With a quick release, the dust container can be easily detached from the dust collection attachment when needed.
