The Makita 18V Compact Lithium-Ion Cordless Impact Driver (model XDT04RW) delivers more torque with less weight and superior ergonomics, with a fast-charging battery for less downtime. It’s part of Makita’s expanding 18V Lithium-Ion series, the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. The Makita 18V battery has the fastest charge time in its category, so the battery spends more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls™. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside. The XDT04RW features a Makita-built 4-pole motor with variable speed (0-2,300 RPM and 0-3,200 IPM). At only 5-7/16-inches long and 2.8 pounds, the XDT04RW has a compact and ergonomic design with less weight for reduced operator fatigue, and a rubberized soft grip for increased comfort on the job. The built-in L.E.D. light illuminates the job area for applications in dark spaces and close quarters.
