The DEWALT DCG405 XR Brushless Grinder has a powerful fan cooled motor with a mesh cover that provides additional motor protection by preventing dust being sucked through the motor. Its electronic clutch reduces the kick back reaction in the event of a pinch or stall. The two position side handle provides greater control, whilst the rubber overmould provides enhanced grip and comfort. For added safety, the electronic brake stops the wheel quickly when the trigger is released. Specification No Load Speed 9,000/min. Disc Diameter 125mm, M14 Spindle. Weight 1.75kg.
