A spiral-cutting tool is a great addition to any toolbox. It can cut through dry wall, tile, hardwood, softwood and more. Before cutting through dry wall with a spiral-cutting tool, make sure there are no live electrical wires or pipes directly behind the surface. Plunge the tool straight into the dry wall at a 90-degree angle (figure A). When cutting outlet openings on dry wall, plunge into the outlet box, using a guide-point bit. Guide the tool until you feel the edge of the outlet box. Gently lift the tool over the edge of the outlet box, and follow the outside contour of the box in a clockwise direction (figure B). To cut through tile, use a carbide-tipped bit with the spiral-cutting tool (figure C). Wear safety glasses for protection from flying debris. Plunge the spiral-cutting tool straight into the tile at a 90-degree angle, and slowly direct it through the area you want to cut (figure D). Creating a Circle-Cutting Jig To cut circles through wood or any other material, use a special circle-cutting jig attached to a spiral-cutting tool. Materials:
Spiral-cutting tool
Non-piloted woodcutting bit with sharp point
Circle-cutting guide
Wood
- Insert the non-piloted woodcutting bit into the spiral-cutting tool (figure E).
- Remove the fence from the tool (figure F). Attach the fence to a circle-cutting guide, then reattach the fence and the guide to the spiral-cutting tool (figure G).
- Use the spiral-cutting tool to drill a pilot hole where you want the center of the circle on the wood (figure H).
- 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 (figure I).
- Use the guide to pivot the tool 360 degrees to cut a perfect circle (figure J).
