DeWalt’s DUSTX+ adhesive installation system includes hollow drill bits to minimize dust when drilling holes in concrete for anchor installation. Compatible with SDS and SDS Max drills, the system uses hollow drill bits and an integrated dust-collection vacuum to reduce harmful silica dust during drilling. Because the dust is collected during drilling, there is no need to blow out the hole when the job is finished, further reducing dust exposure. DeWalt; www.dewalt.com
