DeWALT DWH303DH Cordless Onboard Dust Extractor

This OSHA Table 1 compliant dust extractor works with the DCH273 1 in hammer. It features an OSHA 1926.1153 compliant dust box assembly. With a filter cleaning mechanism and a HEPA filter, it removes 99.97% of airborne particles 0.3 microns or greater. The dust extractor has a powerful built in motor for increased suction during high performance drilling. The 2 sec power-off delay ensures that dust extraction continues after the drill is switched off. It accommodates drill bit diameters up to 5/8 in which allows users to drill overhead for 1/2 in drop-ins.
