The Grinder has up to 54% more power when paired with a Flexvolt battery. The brushless motor delivers 1550 max watts out and up to 9000 rpm. Kickback Brake engages with maximum force to quickly stop the wheel and shut off the grinder when a bind-up occurs. E-Clutch shuts down the motor in under a tenth of a second when a pinch/stall is detected. E-Switch Protection requires the trigger switch to be cycled turned off on in the event of a power outage or other unexpected shutdown to restart.
