Makita is the innovation leader in brushless motor technology, and the 18V LXT? Brushless Impact Driver (XDT13Z, tool only) combines power and run-time for a full range of fastening tasks. The efficient Makita BL? Brushless Motor is electronically controlled and engineered for longer run time, increased power and speed, and longer tool life.It?s part of Makita?s expanding 18V Lithium-Ion system, the world?s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. 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. The variable speed brushless motor delivers 0-3,400 RPM, 0-3,600 IPM, and up to 1,500 in.lbs. of max torque for efficient fastening. It has a compact design at 5? long and weighs only 3.3 pounds (with battery) with an ergonomic soft grip for user comfort. The L.E.D. light illuminates the job area for applications in dark spaces.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.
