The Dewalt DCG200NT wall chaser uses 2 diamond discs to cut a channel into block, brick or concrete walls and floors. Using a hammer the material in-between the two cuts is removed leaving a channel. This channel can then be used to lay pipes or wires below the surface of the wall or floor. This motel features an extremely powerful 54V brushless motor which provides exceptional performance in the most demanding tasks. It is extremely user-friendly thanks to its electronic clutch and break which increase safety upon use.
