The D25303DH Integrated Dust Extraction System attaches directly to DCH273 and DCH274 18V XR SDS-Plus Hammer Drills (Type 2 only), providing on-board dust extraction during concrete and masonry drilling without a separate hose or extractor. An independent built-in motor maintains maximum hammer drill performance with no reduction in drilling speed, and continues operating for two seconds after the trigger is released to clear any debris remaining in the telescopic hose. The on-board dust collection box can be emptied via the DWH079D Dust Box Evacuator for sealed, low-dust disposal.
