With the Dewalt D25304DH-XJ integrated dust extraction unit, you drill cleanly into concrete and masonry without dragging around separate vacuum hoses or bulky external extractors. You attach the unit quickly and without tools directly to your compatible SDS+ hammer drill, such as the DCH283 or DCH333. Because it is powered directly by the hammer drill itself, you maintain full control and maneuverability during overhead drilling and indoor renovations. The washable hepa filter captures 99.5% of fine dust particles down to 0.3 microns, supporting drilling diameters up to 26 mm and depths up to 180 mm. This keeps your workspace clean and minimizes post-job cleanup.
