For the DCH273P2 1" SDS Plus 20V Rotary Hammer

This OSHA Table 1-compliant Dust Extractor works with the DCH273 1" 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 2-second power-off delay ensures that dust extraction continues after the drill is switched off.
