ABSTRACT:
An improved dust collector for a power tool is employed. The dust collector includes a body portion, a neck portion and a head portion, wherein the body portion is disposable on the power tool so that during the cutting operation the body portion will receive and direct the air, dust, and debris to the head portion via the neck portion to either be exhausted out or to be collected in a dust collection volume. Preferably, the body portion has a series of openings to allow the user to view the cutting wheel during the cutting operation. The body portion may also have an internal directional member for efficiently directing the flow of air, dust, and debris. The head portion is preferably rotatably connected to the neck portion to allow the user to rotate the head portion to a desired position.
