Powered by two LXT batteries; X2 LXT technology delivers more power, speed and run time without the hassles of a cord. Makita built electronically controlled BL Motor delivers 5,100 rpm for maximum performance and 50% longer run time per charge. The BL Brushless Motor eliminates carbon brushes, enabling the BL Motor to run cooler and more efficiently for longer life. Automatic Speed Change technology adjusts cutting speed and torque during cut for optimum performance. X2 LXT technology delivers up to 558 cross-cuts per charge in 2x4 SPF lumber and up to 291 cross-cuts per charge in 2x10 SPF lumber using the two 5.0Ah batteries. Large 2.56" cutting capacity at 90 degrees; cuts 3X material in a single pass. Electric brake for maximum productivity 0 degrees - 53 degrees bevel capacity with positive stops at 22.5 degrees, 45 degrees, and 53 degrees. Die-cast magnesium base and blade guard along with a die-cast aluminum blade cover and motor housing provide a lightweight, durable design. Compact and ergonomic design at only 17.5" long.
