The Mac Tools 3/8" Drive 12V MAX Ratchet Kit, No. BRS038-D2, offers a closed head design for improved durability and reduced maintenance, says the company. The glass-filled nylon body is resistant to automotive fluids, and the tool is made from die-cast aluminum to reduce weight. Powered by DeWalt's battery and electronic switch technology, the tool features a variable speed switch with electronic brake to provide control. The anti-marring bumper protects the tool and work surface from damage and an LED worklight illuminates the task. The BRS038-D2 kit includes the ratchet, two Li-ion batteries, one charger and a tool bag.
