The Makita 18V Compact Lithium-Ion Cordless 2-Piece Combo Kit (CT225SYX) is built for the pro-user who demands best-in-class Lithium-Ion cordless tools for drilling, driving and fastening in a compact size. The CT225SYX includes an 18V LXT 1/2 in. driver-drill (XFD10Z) and Impact Driver (XDT11Z) for increased versatility. It's part of Makita's expanding 18V LXT System, the world's largest cordless tool system powered by 18V lithium-ion slide-style batteries. Makita 18V LXT 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 Lithium-Ion Batteries with the star symbol on the battery indicating Star Protection inside.
