The 18V LXT? Lithium-Ion Cordless 5″ Random Orbit Sander (model XOB01Z, tool only) delivers increased efficiency and mobility to woodworkers. The XOB01Z features three speed settings, superior ergonomics and up to 40 minutes of run time on a single charge (battery sold separately). Match the speed to the application with three speed settings (7,000/9,500/11,000 OPM), which are easily changed with a one-touch electronic control switch. The large 1/8? random orbit action is engineered for efficient sanding, fast material removal, and a swirl-free finish. The pad brake reduces free-spin for improved overall finish, and a control system regulates pad speed at start-up. The XOB01Z uses quick-change 5? (8-hole) hook-and-loop abrasive paper for increased versatility. It?s part of Makita?s expanding 18V Lithium-Ion series, the world?s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V 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 18V LXT? and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
