This kit combines an 18-volt drill/driver and an impact driver to deliver a potent one-two punch for all drilling and fastening applications. The compact batteries charge quickly, but as our 18-volt drill/driver lab test proved, some of those small batteries have a shorter life span. Not so here—we had enough juice to drill dozens of pilot holes and fill them with 2-inch lag screws.
