ABSTRACT:
The vacuum attachment for a router table removes wood chips, dust, and debris during operation of the router. The attachment includes a hollow annular housing adapted for mounting about the router. The annular housing has an upper edge, a lower edge and at least one sidewall, with the upper and lower edges being adapted for sealing engagement with an external surface of the router. At least one vent hole is formed through the annular housing and a vacuum port is formed therethrough, so that a vacuum source connected to the vacuum port is in fluid communication with an interior of the annular housing. When the annular housing is mounted about the router and aligned with an opening in the base of the router, the vacuum source draws debris away from the router and the router table, with environmental air entering the interior through the vent holes.
