The Makita 18 V LXT® Lithium-Ion cordless impact driver (model XDT11R) delivers power and speed in a compact size for a full range of driving and fastening tasks, with a fast-charging 18 V compact Lithium-Ion battery for less downtime. It's part of Makita's expanding 18 V Lithium-Ion Series, the world's largest cordless tool line-up powered by an 18 V Lithium-Ion slide-style battery. Makita 18 V Lithium-Ion batteries have the fastest charge times in their categories, so they spend 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 18 V LXT® and compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside. The XDT11R features a Makita-built 4-pole motor with variable speed (0 to 2900 rpm and 0 to 3500 ipm) that delivers 1460 in-lb of max torque
