Grinders with electronic kickback protection

Electronic shock protection

— a system that monitors the operation of the motor and instantly reduces the speed or cuts off power in the event of a sudden jamming of the plate or disc. Unlike simple mechanics, the electronics analyze the current and rotational speed, recognize an "abnormal" jerk, and prevent the tool from being wrenched from the user's hands when the abrasive catches on a protrusion, edge of a part, or a screw in wood. This protection is especially useful when working at heights, on a ladder, or when sanding doors, railings, or car body parts: the risk of injury and damage to the workpiece is significantly lower, and the grinder with electronic kickback protection lasts longer because the motor and gearbox suffer less from impact loads.
