The Dust Extractor Attachment with HEPA Filter (DX10) is for use with the 1-3/16” AVT® Rotary Hammer (HR3011FC, sold separately). It captures concrete dust during drilling and is activated by the tool. The Dust Extractor Attachment features a HEPA filter engineered to capture 99.97% of dust particles (size .3 microns and larger) for improved dust collection and OSHA Table 1 compliance. The high-capacity dust container is transparent and provides an accurate level indicator of collected material. The extractor extension allows for drilling up to 7-1/2” deep and up to 1-3/16” diameter holes. The depth-stop adjustment button allows for an accurate drilling depth.
