A dust collection system for use in connection with a portable power tool is provided. The dust collection system generally includes a dust collection port having an intake that is interconnected to an air impeller by an intake duct. The impeller is driven by a motor, to create a vacuum at the intake port of the dust collection port. The outlet of the air impeller is in communication with a dust collection volume. In operation, the dust collection system is fixed to a portable power tool. Dust created during sawing or other operations is collected by the dust collection port, and is drawn away from the location at which the dust is created by a vacuum established by the air impeller at the intake port. The dust thus collected is deposited in the dust collection volume, which may include a filter bag. The present invention provides for the efficient collection of potentially harmful particulates created during sawing or other operations, without adversely affecting the portability of the portable tool to which the system is affixed.
