The XT442 includes a 2-speed 1/2 in. hammer driver-drill with 480 in. lbs. of Max Torque, a 6-1/2 in. circular saw that will cut 2X material at 45°, a reciprocating saw with 0-2,800 strokes per minute and a 4-position rechargeable flashlight with Xenon bulb (DML185). The kit also includes 2 fast-charging 18-Volt LXT Lithium-Ion 3.0Ah batteries, Rapid Optimum Charger and tool bag. It's part of Makita's expanding 18-Volt Lithium-Ion system, the world's largest cordless tool system powered by 18-Volt Lithium-Ion slide-style batteries. 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.
