Makita is a leader in brushless motor technology and the Makita 18-Volt 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. It's part of Makita's expanding 18-Volt Lithium-Ion series, the world's largest cordless tool line-up powered by an 18-Volt Lithium-Ion slide-style battery. Makita 18-Volt Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. 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 18-Volt LXT and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
