The DEWALT DWH304DH Onboard Rotary Hammer Dust Extractor is an OSHA Table 1-compliant dust collection system built for the DCH293 cordless rotary hammer and, with supplied adapters, the corded D25333 1-1/8 in. SDS Plus rotary hammer. It mechanically attaches to and is powered by the tool's motor, so no separate battery or vacuum hose is required to run dust collection, helping maximize runtime of the host tool's battery. A HEPA filter with a filter cleaning mechanism removes 99.97% of airborne particles 0.3 microns or larger, while a powerful fan assembly boosts suction during high-performance drilling. The clear, durable dust box shows users at a glance when it needs to be emptied, and a replaceable dust nozzle simplifies maintenance. An adjustable depth gauge helps technicians drill accurate anchor holes up to 1 in. in diameter and 10 in. deep, and the compact design fits into tight spaces such as scissor lifts and areas between overhead pipes and ductwork.
