The combination includes a router tool and a vertically adjustable tool holder for holding and carrying the router tool with the router cutter axis parallel to the upper surface of the tool table attached to the body. The tool holder is formed substantially in the shape of a sector of a circle and is attached to the body by a pivotal attachment substantially at the center of the arc of the sector. The tool holder includes a circular arc shaped gear rack at the arcuate edge thereof, and a pinion gear is rotatably attached to the body and in engagement with the gear rack or vertical adjustment of the tool holder.
