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. 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. Bl brushless motor eliminates carbon brushes, enabling the bl motor to run cooler and more efficiently for longer life; delivers 6,000 rpm. (2) 18-Volt lxt lithium-ion batteries deliver corded power without leaving the 18-Volt lxt battery platform (batteries not included). Electric brake stops the grinding or cut-off wheel in 4.5 seconds or less for maximum productivity. Active Feedback-sensing Technology (AFT) turns the motor off if rotation of the wheel is suddenly forced to stop. Automatic speed change technology adjusts speed and torque during operation for optimum performance. Vibration absorbing back handle is isolated from the motor housing effectively reducing vibration to the operator’s hands. Rear handle paddle switch with no lock-on feature. Efficient bl brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge. Electronically-controlled bl brushless motor efficiently uses energy to match torque and rpm to the changing demands of the application. Anti-restart protection engineered to prevent motor start up when battery is inserted with switch locked on. Weighs only 13.01 lbs. With battery (battery not included) for reduced operator fatigue. LED battery charge indicator alerts user of drained power for each of the 2-batteries (batteries not included). Large spindle lock button for easier wheel changes while wearing gloves. Wire mesh intake covers are engineered to prevent debris from entering motor. Tool-less wheel guard for quick and easy adjustments. UPC Code # 088381851473.
