The 18V LXT Lithium-Ion Cordless 1/2 in. Driver-Drill (model XFD07Z, tool only, battery sold separately) breaks new ground with a full 1,090 in. lbs. Of torque for the most demanding drilling and driving applications. It's powered by a Makita Brushless Motor for longer run time, increased power and speed, and longer tool life. The XPH07Z is positioned at the top of Makita's deep line-up of driver-drills, and is a workhorse tool engineered with durability features for operation in harsh job site conditions. 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.
