Abstract
A power table tool having an outlet port positioned relative to the cutting member of the tool so that the dust and other debris generated by the cutting member can be removed from the interior of the tool assembly through an exhaust system. A guard member is provided for the outlet port to prevent insertion of extraneous matter into the interior of the tool as well as to protect the outlet from clogging as a result of the removal of the sawdust and other debris from the interior. The guard member is structured in a manner such that the area of the openings presented in the guard member is greater than about 100% of the area of the outlet port itself. The port is specifically aligned relative to the cutting member in order to enhance the removal of the sawdust and debris from the interior of the tool.
