Makita, a pioneer in Brushless motor technology and battery innovation, combines both in the 18V X2 LXT® (36V) Lithium-Ion Brushless 7-1/4” Circular saw kit (XSH08Z). 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 the XSH08Z As they use across the expansive Makita 18V 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 two fully-charged 5.0Ah batteries (Sod separately). The saw has a large 2-5/8” cutting capacity at 90 degrees. 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. The saw has a die-cast magnesium base, blade guard and blade cover. The base is compatible with optional guide rails (sold separately) for dead-on straight or bevel cutting. The compatible base means there is No need for an adapter to use with an optional guide rail. Added features include an Electric brake for maximum productivity and a built-in dust blower to clean the line-of-cut and a built-in tether notch (tether sold separately). the XSH08Z includes a 7-1/4” 24T carbide-tipped Max Efficiency Miter saw blade. The thin-kerf design provides smoother cuts with less drag on the motor and minimal material loss. Compared to standard blades The max Efficiency Miter saw blade delivers up to 70% faster cutting.
