The 18V LXT Lithium-Ion 1/2 in. The XPH03Z has the torque and speed that contractors demand, and it is engineered for increased resistance to water and dust. For drilling and driving, Makita has delivered a total solution. (battery and charger sold separately) 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.
