The Makita 18V X2 LXT (36V) Brushless Recipro Saw (XRJ06Z) delivers faster cutting and demolition performance. The XRJ06Z combines two 18V LXT Lithium-Ion batteries for 36V power and performance. The efficient brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge. It features "tool-less" blade change, electric brake, and a refined crank mechanism design that minimizes blade deflection and reduces vibration.
