Step 1: Position the Fence

Insert the non-piloted woodcutting bit into the spiral-cutting tool (Image 1). Remove the fence from the tool (Image 2). Attach the fence to a circle-cutting guide, then reattach the fence and the guide to the spiral-cutting tool (Image 3).

Step 2: Drill a Hole and Make the Cut

Use the spiral-cutting tool to drill a pilot hole where you want the center of the circle on the wood (Image 1). Insert the center point of the guide into the pilot hole. Tilt the spiral cutter at a 45-degree angle before plunging into the wood to make the cut (Image 2). Use the guide to pivot the tool 360 degrees to cut a perfect circle (Image 3).
