The 18-Volt LXT Lithium-Ion Cordless Drywall Screwdriver (model XSF01Z, tool only, battery and charger sold separately) is engineered with a pistol grip design with a large 2-finger trigger and delivers 4,000 RPM to handle drywall and framing applications. It combines the power of a corded drywall screwdriver with the convenience of a cordless tool. It is engineered for hanging sheetrock, metal framing, installing subfloors, backer board and decking applications. 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.
