Innovative brushless motor technology offers higher performance, more compact dimensions, longer runtime per battery charge, and an extended lifespan. The ultra-flat gearbox head allows for work at angles of up to 40 degrees. Epoxy-coated windings protect the motor from abrasive dust particles. An optimized ventilation system effectively cools the angle grinder and the electronics during use, increasing its lifespan. The electronic brake reliably stops the disc in under two seconds. The electronic clutch automatically shuts off the tool when it gets blocked, protecting both the user and the machine. The combination of the electronic clutch and brake minimizes the risks of kickback even more effectively. The overload protection safeguards both the user and the machine. The restart protection prevents the accidental starting of the angle grinder during battery changes. Protective grids for the cooling vents shield the motor from coarse dust particles. The tool-free guard allows for quick adjustments. This standard model is optimally suited for existing 18-volt XR or 54-volt XR FLEXVOLT batteries of all amp-hour classes.
