18V 3/8" LXT Lithium-Ion sub-compact brushless cordless impact wrench TOOL ONLY. Makita sub-compact gives users 12V handling with 18V run time and compatibility with the world's largest 18V lithium-ion cordless tool system. This impact wrench is ideal for working in tight spaces and for overhead applications. It has an efficient Makita BL brushless motor engineered for up to 50 percent longer run time, increased power and speed, and longer tool life. It has variable two-speed with 0-1,300/0-2,400 RPM and 0-2,000/0-3,600 IPM and up to 130 ft.lbs. of max torque. The compact size and lower weight mean reduced fatigue for operators, especially for overhead applications. For added convenience, the reverse rotation auto-stop mode stops rotation and impact when the fastener is loosened adequately.
