The Makita 18V LXT® Lithium-Ion Cordless 4-1/2” Cut-Off/Angle Grinder (model XAG01Z, tool only) delivers 10,000 RPM of compact grinding power to the jobsite. The XAG01Z is engineered to grind, cut, and sand a wide range of materials including tile, concrete, pipe, conduit, and more. 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. Makita-Built Motor Engineered for Versatile Power The XAG01Z features a Makita-built high torque motor that delivers 10,000 RPM, as well as an all-metal helical gear transmission which is longer lasting and delivers a more efficient transmission of energy when compared to angled gears. The XAG01Z also has a built-in electronic control circuit with L.E.D. warning lights for overload protection, and an electronic current limiter that automatically shuts off the current when the motor continues to be overloaded. This feature protects the motor for longer tool life. Ergonomic Design in a Compact Size The XAG01Z weighs only 5.0 lbs. (with battery, sold separately) with a more compact design at only 12-1/2” long. The ergonomic shape fits like a glove with even pressure and even control and the built-in L.E.D. light illuminates the work surface for more efficient work. Versatile Design for a Range of Applications The XAG01Z will grind, cut, and sand through a range of materials including tile, concrete, all-thread, Unistrut®, pipe, channel iron, copper pipe, tubing, and more. It is ideal for tile setters, masons, welders, electricians, pipe fitters, sprinkler installers, HVAC, plumbers and any general contractor seeking a best-in-class engineered cordless cut-off/angle grinder.
