Makita, a pioneer in brushless motor technology and battery innovation, combines both in the 18-Volt X2 LXT (36-Volt) Lithium-Ion Brushless 7-1/4 Circular Saw Kit (XSH08Z). It's powered by two 18-Volt LXT Lithium-Ion batteries for maximum performance, and has an electronically-controlled BL Brushless motor that matches torque and RPM to the application. Makita 18-Volt 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 1 battery platform, using the same fast-charging 18-Volt batteries with the XSH08Z as they use across the expansive Makita 18-Volt LXT cordless tool system. In internal testing, the XSH08Z made up to 610 cross-cuts per charge in 2x4 SPF lumber and up to 320 crosscuts per charge in 2x10 SPF lumber using 2 fully-charged 5.0 Ah batteries (sod separately). The saw has a large 2-5/8 cutting capacity at 90°. The XSH08Z has a long list of features for efficient cutting without the cord. The electronically-controlled brushless motor delivers a full 6,000 RPM for efficient cutting, with Automatic Speed Change technology to adjust the cutting speed and torque under load for optimum performance.
