Makita is the innovation leader in brushless motor technology and the 18 V LXT® brushless impact driver 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 18 V Lithium-Ion system, the world's largest cordless tool system powered by 18 V Lithium-Ion slide-style batteries. 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. The variable speed brushless motor delivers 0 to 3400 rpm, 0 to 3600 ipm and up to 1500 in-lb of max torque for efficient fastening. It has a compact design at 5 in L and weighs only 3.3 lb with an ergonomic soft grip for user comfort. The LED 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 18 V LXT® and compact Lithium-Ion batteries with the star symbol on the battery indicating star protection inside.
