Milwaukee® HAMMERVAC™ Dedicated Dust Extractor (M18CDEX-0) features an inline dedicated design engineered to connect directly to and be power by the M18 FUEL® 26mm SDS Plus Rotary Hammer (M18CH-0). This design allows for a very compact HAMMERVAC™ and rotary hammer combination to fit in the most confined work spaces. Utilising the same replaceable certified HEPA filter as other HAMMERVACS™, which filter 99.97% of all particles greater than 0.3µm, means more compatibility on the jobsite. For accurate hole depths, this product is built with an adjustable depth stop and ruler for easy and precise adjustments. Featuring a high capacity dust box, users can now work longer without emptying dust box as often.
