The Makita 18V LXT® Lithium-Ion Cordless 2-Piece Combo Kit packs the cordless tools you’ll need for a full range of drilling, driving, and fastening applications. The XT211MB includes a versatile ½” hammer driver-drill with all-metal gear construction for applications in wood, metal and masonry. The powerful impact driver weighs only 3.3 lbs., yet delivers a full 1,420 in.lbs. of torque. The 18V LXT® 4.0Ah battery provides 35% more run time per charge than the 18V 3.0Ah battery (BL1830), with a category-leading charge time of only 40 minutes for less downtime and increased productivity. For added convenience, the batteries feature an on-board L.E.D. charge level indicator. 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. Makita 18V 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 18V LXT® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
