Makita 18V LXT LithiumIon Brushless Cordless 41/2" / 5" XLOCK Angle Grinde

Technology: The Active Feedback-sensing Technology (AFT) turns the motor off if the wheel's rotation is suddenly forced to stop. The Automatic Speed Change technology adjusts speed and torque during operation for optimum performance
Features: The soft start suppresses start-up reactions for smooth start-ups and longer gear life. It offers anti-restart protection to prevent motor start-up when the battery is inserted with the switch locked on
Design: It is compact and ergonomic, only 14-3/4 inch long, and weighs only 6.6 lb with a battery (battery not included) for reduced operator fatigue. The soft rubberized grip provides increased comfort on the job
Efficient-Controlled: The electronically-controlled B.L. Brushless Motor efficiently uses energy to match torque and R.P.M. to the changing demands of the application. It is equipped with Star Protection Computer Controls to protect against overloading, over-discharging, and overheating
Rapid Optimum Charger: The charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage, and temperature (battery and charger are sold separately)
