Makita is a leader in Brushless Motor technology, and the Makita 18V LXT Lithium-Ion Brushless cordless jig saw (model XVJ02Z, tool only, battery and charger sold separately) seamlessly combines precision and power with the efficiency of Brushless. The XVJ02Z is engineered to deliver the power and performance of a corded jig saw without the hassles of a cord. It is ideal for professional woodworkers, cabinetry makers, specialized residential construction workers and any pro-contractor seeking a best-in-class cordless jig saw. For improved tool performance and extended battery life, Makita created STAR Protection computer controls. STAR Protection is communication technology that allows the star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT and compact Lithium-Ion batteries with the star symbol on the battery indicating STAR Protection inside. The XVJ02Z features a Brushless Motor and has 3 orbital settings plus straight cutting for faster and more accurate cuts in a variety of materials. The variable speed control dial (800 to 3,500 SPM) enables users to match the speed to the application. In addition, the efficient BL Brushless Motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge than similar Xenon-brushless tools. Electronic controls efficiently use battery energy to match the changing demands of the application for increased power and speed when needed.
