The 18 V LXT® Lithium-Ion 1/2 in hammer driver-drill (model XPH03Z, tool only) delivers a full 750 in-lb of max torque and 18% more speed, yet it is more compact and weighs less than the previous model. 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. 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 XPH03Z features Makita extreme protection technology (XPT™). XPT™ is a protective seal inside the tool engineered for improved water resistance by channeling water and dust from the tool's key internal components. The XPT™ equipped XPH03Z is engineered for improved operation in harsh jobsite conditions.
