Makita 18V LXT Brushless Tools feature the efficient Makita BL Brushless Motor, which is electronically-controlled to optimize battery energy use. Electronic controls constantly monitor the changing demands of each application, regulating and adjusting the flow of current to the BL Motor in real-time and delivering optimum energy output from the battery so users get increased RPM and torque when necessary. And with no carbon brushes, the BL Motor runs cooler and more efficiently for longer life. BL Motor tools are part of Makita’s 18V LXT line-up, with over 50 tools powered by one 18V lithium-ion battery.
