The Makita 18V LXT® Lithium-Ion Cordless ¼” Die Grinder (model XDG01) delivers speed and portability in a compact size. It is engineered for a range of metalworking surface-prep applications including grinding, smoothing and cutting. 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. 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® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside. The XDG01 features a Makita-built motor that delivers 25,000 RPM for faster grinding. The compact design with barrel grip weighs only 4.4 lbs. (with battery), and the stepped-neck design makes it ideal for working in tight spaces. The slide switch has a lock-on for operator convenience, with vent slots designed to direct exhaust air away from the user. The XDG01 also features a solid aluminum housing for added durability. The XDG01 includes a built-in L.E.D. protection circuit with over-torque to protect the motor. In addition, the L.E.D. light flashes red when it is time to recharge the battery. The XDG01 delivers speed and portability in a compact size, and is ideal for a range of metalworking surface-prep applications.
