The Makita 18V LXT Lithium-Ion Cordless Impact Driver (model XDT11SY) delivers power and speed in a compact size for a full range of driving and fastening tasks, with a fast-charging 18V LXT Lithium-Ion Battery for less downtime. 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. 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. The XDT11SY features a Makita-built 4-pole motor with variable speed (0-2,900 RPM and 0-3,500 IPM) that delivers 1,460 in.lbs. of Max Torque. At only 5-3/8 in. long and 2.8 pounds (with battery), it has a compact and ergonomic design with less weight for reduced operator fatigue and a rubberized soft grip for increased comfort on the job. Makita's entire line-up of impact drivers including the XDT11SY is engineered with a proprietary hammer and anvil impact mechanism that is manufactured using the best raw materials with the highest quality steel. With Extreme Protection Technology (XPT), the XDT11SY is engineered for improved water and dust resistance for operation in harsh job site conditions.
