The XOB01Z features three speed settings, superior ergonomics and up to 40 min of run time on a single charge (battery sold separately). Match the speed to the application with three speed settings (7000/9500/11000 opm), which are easily changed with a one-touch electronic control switch. The large 1/8 in 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 in (8-hole) hook-and-loop abrasive paper for increased versatility. It's part of Makita's expanding 18 V lithium-ion series, the world's largest cordless tool line up powered by an 18 V lithium-ion slide style battery. Makita 18 V 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 V LXT and compact lithium-ion batteries with the star symbol on the battery indicating Star Protection inside.
