Abstract: A power tool attachment for table saws comprises a platform to extend the saw table work surface. The power tool attachment has openings to receive bolts extending from an edge of the table of the table saw, so that the power tool attachment may be easily connected and detached from conventional table saws, with the surface of the table and platform coplanar, and with the platform between guide bars of the table saw. A router or other tool is attached to the bottom of the platform so that the tool cutting element extends through a hole in the platform, to engage work placed on the platform surface. A cover is provided for the platform hole when the router or other tool is not in use. The table saw and power tool attachment may be used simultaneously or independently. Flanges project perpendicularly from the periphery of the platform on the power tool attachment to provide greater strength to the platform while reducing its weight.
