Using this Lenox hole cutter kit is quite straightforward. First, select the appropriate hole cutter size for your project from the included sizes. Attach the selected cutter to the arbor that fits it. Then, use the 1/4' split point pilot drill bit to start the hole. Make sure to secure the material you're working on firmly. When drilling, apply steady pressure but don't force it too much. The carbide teeth will do the work efficiently. As for the over - drill stopper, it will stop the tool from going too deep automatically. For maintenance, after each use, clean the hole cutters and the drill bit with a brush to remove any debris. Keep the kit in a dry place to prevent rust. If the carbide teeth start to dull, it might be time to replace the cutter. Also, always wear safety goggles when using this kit to protect your eyes from flying debris.
