Using the Lenox 3004141L hole saw is easy. First, make sure your workpiece is properly secured. Then, attach the hole saw to your drill. When starting the cut, apply gentle pressure and let the advanced tooth geometry do its job. As you cut, the SPEED SLOT design will clear sawdust and chips on its own. If a plug gets stuck, use a screwdriver at the leverage points to remove it. When cutting through metal, expect a longer - lasting performance compared to other hole saws. For maintenance, after each use, clean the hole saw with a brush to remove any debris. Store it in a dry place to prevent rust. Always wear safety goggles when using this tool to protect your eyes from flying chips.
