Makita delivers corded grinding performance without the cord with the 18-Volt LXT Lithium-Ion Brushless 4-1/2 in./5 in. Cut-Off/Angle Grinder (tool only， battery and charger sold separately). It's powered by a Makita brushless motor for longer run time， increased power and speed and longer tool life. For the most demanding applications， Makita's exclusive Automatic Speed Change Technology automatically adjusts speed and torque during operation for optimal performance. The XAG04Z is ideal for grinding， cutting and sanding a wide range of materials including tile， concrete， pipe， conduit and more. Its 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.
