18V 7-1/4" X2 (36V) LXT Lithium-Ion brushless cordless rear handle circular saw (5.0Ah). Makita, a pioneer in brushless motor technology and battery innovation, combines both in the 18V X2 (36V) LXT Lithium-Ion brushless rear handle circular saw. It's powered by two 18V LXT Lithium-Ion batteries for maximum performance, and has an electronically-controlled BL Brushless motor that matches torque and RPM to the application. Makita 18V X2 means freedom from the cord, even for demanding applications like cutting sheet and dimensional lumber that traditionally called for a corded saw. Best of all, users can remain in one battery platform, using the same fast-charging 18V batteries with this saw as they use across the expansive Makita 18V LXT cordless tool series.
