Makita, a pioneer in brushless motor technology and battery innovation, combines both in the 18V X2 LXT® (36V) Lithium-Ion Brushless 9” Paddle Switch Cut-Off/Angle Grinder with Electric Brake. It's powered by two 18V Lithium-Ion batteries (sold separately) for 36V power and performance, and has an electronically-controlled BL™ Brushless motor that matches torque and RPM to the application. Makita 18V X2 means freedom from the cord, even for demanding applications like grinding and cut-off applications that often call for a corded grinder. Best of all, users can remain in one battery platform, using the same fast-charging 18V batteries on the XAG13 as they use across the Makita 18V LXT® cordless tool system. The XAG13 is equipped with efficiency features for maximum performance. The electric brake stops the grinding or cut-off wheel in 4.5 seconds or less for maximum productivity, and the Electronic Torque Control turns the motor off if rotation speed suddenly slows or the wheel is forced to a stop. For consistent performance, Automatic Speed Change™ technology adjust speed and torque during operation. For added comfort, the vibration absorbing back handle is isolated from the motor housing for reduced vibration, and the soft start feature suppresses start-up reaction for smoother start-ups and longer gear life. It has a no lock-on rear paddle trigger switch, and the anti-restart protection is engineered to prevent motor start-up when the battery is inserted with the switch locked on. It’s part of Makita’s expanding 18V Lithium-Ion system, the world’s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. 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.
